Remedy rice herbicide injury

1 , re-inserted ( throwing ) seedlings : seedlings injury diagnosed confirm the severity of etiolated seedlings accounted for 8 percent , to raise seedlings immediately interpolation ( throwing ) . Methods of operation : first row Kiyota of water, light emission Cho once, then plow , then plug ( throwing ) seedlings . In recent years , seeding and plug ( throwing ) seedling season earlier than the traditional season 7-15 days . Found that the injury to the interpolation is usually 5-10 days , seasons contradictions are not prominent.

2, to strengthen management of fertilizer and cultivation : Discovery injury plots first flush has been pressure sprayer spraying the fields of water , poured fresh running water . Yun Tian Zhonggeng followed , the topsoil plunged into deep soil adsorption agents , reducing the role of pesticides on rice roots . Yun Tian Mushi after 2-3 days sleeping four kilograms of fertilizer imports , promote root leaves , accelerate growth .

3 , the application of rooting Category: drainage, Yun Tian and after fertilization , the best Mushi concentration of 200 mg / kg of rooting powder 200 kg , has a good effect on promoting root ,bottle sprayer  root number increased from 25 to 40% , can be accelerated growth rate .

You can choose according to herbicide weed species

Plant Protection Station , Jiangsu Province , according to survey data , the local weed has 15 families and 27 species of heavy damage to wheat are: A.aequalis hard grass , bluegrass ,bottle sprayer wild oats, ryegrass , cleavers , Fan branches, vetch , shepherd's purse, sophia , speedwell , buddha seat, Euphorbia , pure rice chestnut , Cephalanoplos and reed . We can simply put these weeds and broadleaf weeds are divided into two major categories of weeds .

Control weeds can choose: Chlortoluron , isoproturon , acetochlor, fenoxaprop , metsulfuron methyl , etc. . Because different weed populations sensitive to these different responses herbicides , therefore the choice of the medicine should be further refined.

Such as: to see the wheat straw, wild oat -based plots , you can choose fenoxaprop be controlling . Alkyne oxalic acid spectrum herbicide fenoxaprop slightly wider than some , better than weeding Fenoxaprop , 4-6 grams per acre effective content in the case of controlling before winter ryegrass , hard difficult to control grass weeds ; chlorotoluron and isoproturon can effectively control the majority of annual grass weeds and some broadleaf weeds , especially isoproturon wheat variety is still the current controlling weeds preferred pharmacy .

Broadleaf weeds in wheat fields more types of herbicides is also more appropriate , it should be selected according to the specific weed communities .

Currently registered broadleaf weeds in wheat herbicide varieties: tribenuron , thifensulfuron , Bensulfuron , A , chlorsulfuron ( because A , chlorsulfuron in PH> 7 slow decomposition in soil residual injury heavier, dry area north of the Yangtze disabled ) MCPA ,2.4-D butyl ester , fluroxypyr , Fluoroglycofen ethers, ketones azole grass , grass amine sulfonamide double fluoride . Tribenuron which is still headed varieties , knapsack power sprayer in order to expand the spectrum herbicide , improve the speed and weeding weeding effect , often using complex methods . Such as controlling cleavers , speedwell , sophia , shepherd's purse , etc. Optional: tribenuron + Fluoroglycofen ether ; grass tribenuron + yl ketone ; chlorofluorocarbons than Acetic Acid + MCPA and so on.

Control in Noe stork, Mak public , Vetch , chickweed , etc. Optional: fluroxypyr + MCPA ; azole metribuzin + MCPA and so on.

There are three yuan compounding agents such as azole oxadiazon + tribenuron + MCPA can basically controlling broadleaf weeds in wheat fields in all .

Pesticide use aircraft can also help

Aircraft spraying method . Pesticides with aircraft , powders , granules , baits and other withdrawal uniformly applied within the target area of application methods , also known as air spraying method . It is the effect of the highest application methods for contiguous planting crops , orchards, forests, grasslands, locust breeding plots of wasteland and beach etc. agricultural sprayers spraying . For the aircraft spraying pesticide formulations are powders , wettable powders, water dispersible granules , suspensions, dry suspensions, emulsifiable concentrates, liquid, oil , granules and the like . As particles drift severe dusting aircraft , has been rarely used , even in the morning dusting should also be operating under steady flow conditions , aircraft ground powder powder powder for a little thicker than some . Can be dubbed to water suspension formulations for high- volume spray , when mixed with other formulations are required to prevent particles flocculation . May be formulated for water cream emulsion dosage forms and for high capacity and low volume spray , for low- volume spraying may be added in the amount of spray solution of urea , potassium phosphate dioxide to reduce the droplet evaporation. ULV spray oil directly to its flash point not less than 70 ℃.
Aircraft spraying pesticides, available capacity and ULV low ; low volume spray spray volume of 10-50 l / ha ; ultra low volume spray spray volume of l ~ 5 l / ha ; General required droplet coverage density of 20 / cm 2 or more. Aerial spraying of fungicide tag type , generally use high-volume spray , spray volume of 50 liters / ha or more ; spraying fungicides can be low-volume spray , spray volume of 20 to 50 l / ha. Aerial backpack sprayers spraying of herbicides, usually low-volume sprays, spray volume of 10 to 50 l / ha , the use of wettable powder and 40 to 50 l / ha . Aircraft applicator rodenticides, generally in the forest and grassland Shi bait or poison pill .

Aircraft spraying operation time , usually half an hour after sunrise and half an hour before sunset , as the conditions are ripe , but also night operations. Job wind: Dusting is not greater than 3 m / s, spray or spray particulate agent is not greater than 4 m / sec, sprinkle granules of not more than 6 m / s. Flight altitude and effective spray cap varies by model .

Post-disaster animal epidemic prevention is the key

After the flood, to be "no big epidemic after the disaster," the key to a good job is on the death of livestock and poultry harmless treatment. Just attach great importance to science and epidemic prevention, hand pressure sprayer discharge water, cleaning pens, improve the environment, thorough disinfection, can effectively prevent and control disease epidemic.

Good herd immunity

Focus disinfection herd, pig and playgrounds, slaughterhouse (points), sales floor, warehouse, herd transport vehicles, appliances, water disinfectants used bleach, chlorine preparations, farm environmental disinfection can use caustic soda, lime and chlorine preparations; water-related disasters can easily cause a variety of animal infectious diseases, parasitic diseases are endemic, herd immunity to do work on the new Bulan or exceed the immune protection of pigs, to immediately carry out foot and mouth disease, highly pathogenic blue ear disease, swine fever vaccine premium-free; strengthen management, good barn ventilation to keep indoor air fresh, strengthen water management, maintaining relatively dry discounted timely cooling, perfume sprayer in the feed appropriate to add health drugs to improve herd immunity.

Alachlor and acetochlor cause injury case

Alachlor

And Ming Lasuo in acid and alkaline hydrolysis conditions . Allow corn residues

0.05%. The eyes and skin have a strong stimulating effect. Commercially available 43% and 48% EC and 10%, 15 % of the granules. Alachlor is a selective preemergence herbicide use may control annual grass weeds and certain broadleaf weeds. Cornfield after sowing or planting weeds sprout after premedication , 43% EC 175 to 300 grams per acre , watered 50 to 60 kg , evenly backpack garden sprayers spray in topsoil ( arid regions after drug shallow soil mixing 2 to 4 cm ) . If splashed into the eyes and skin , rinse immediately with water and seek medical advice as soon as possible , if swallowed, should be immediately sent to hospital , induce vomiting or gastric lavage with 5% sodium bicarbonate solution .

Acetochlor

Acetochlor and alachlor belong acid herbicides , mild eye and skin irritation . Preparations are 43% and

50% of the EC. Is a selective preemergence herbicide acetochlor dry land , in the soil and lasts eight weeks or more, a pesticide can control the entire growth period without weeds . Can control annual grassy weeds, but perennial weeds invalid. Weeds on the main absorption site is acetochlor coleoptile must therefore be applied in pre-emergence weed . Per acre with 50 % of the EC 50 to 70 g of soil humidity of the southern upland acre with 30 to 60 grams per acre upland Northeast

130 grams , add water, 40 to 60 kg , in after sowing before tree sprayer spraying. Cucumber , rice, spinach , wheat, leek , millet, sorghum and other crops on acetochlor sensitive and should not be used .

Scientific understanding and responding to the injury occurred

Injury due to the performance of crop species , pharmacy characteristics , dose and mode of application -specific, can be divided into the following types:

Growth arrest and die even as Yaojibanzhong or delayed emergence herbicide for soil treatment or lower germination rate ; crop growing season misuse Herbicide back sprayersspraying both leaf or soil treatment plants are causing yellowing , wilt .

Burns leaf tissue . Such as leaf wilt , wilting , coke side , etc. , occurs in young tissues broadleaf plants , the use of emulsions prone . Leaves and fruits on the local cell damage may also cause different color spots , reducing vegetable and fruit quality.

Malformations, including leaf , wrinkled , tufted, clubroot , chicken root , deformed ear ( fruit ) and so on. If booting the use of hormones in wheat herbicide 2,4 - butylate cause ear deformities ; tomato dip flower caused by abnormal fruit and so on.

Chlorotic . If using long , ureas chloroplasts herbicide damage , performance leaves yellowing, whitening , the latter will appear off leaves or fruit , or leaves , young shoots scorch .

Infertility, is not true. Mainly refers to the reproductive stages of a pharmaceutical crop effects, such as rice booting misuse of glyphosate , will increase the empty flat rate .

Observed that all of these symptoms, determine the initial crop hurt, but proved to be caused by the need to do the following pharmaceutical Survey:

View medication time and the time relationship of adverse reactions . Role of direct, acute onset of phytotoxicity after application can occur within hours or days , it is easier to establish contact . Chronic injury symptoms appear slowly , even in the Xiacha only manifested , but after exclusion of other special circumstances you can still find some connection .

Comparative survey medication and without medication, using different agents after crop conditions .

Symptoms of drug mechanism of action and whether the link between features .

For suspected acute injury , optional normal growth of the plots by the previous method and dosage liquid sprayer spraying again to observe whether there is the same symptoms .

If necessary, ask the professional sector to take soil , irrigation and non- normal plants for pesticide residue testing.

Different types of wallpaper cleaning and maintenance methods

1, foam wallpaper

Foam wallpaper with 100 g / m² for the base paper, coated 300 to 400 g / m² PVC paste resin mixed with a foaming agent, foaming after printing. Such wallpaper appear thicker than ordinary wallpaper, soft. Including high resilient foam wallpaper surface was uneven; low foaming wallpaper is printed on the plane in foam patterns, shaped like a relief, wood, tile and other effects.

2, the natural effect wallpaper
It is made of grass, wood, leaves, etc. into the surface layer of wallpaper, style simple and natural, elegant and generous, rich flavor of life, giving the feeling of getting back to basics. If it gets the kind of drink or beer spill liquid into the wallpaper, it is easy and wallpapers chemical reaction, so that wallpaper discoloration and stains very obvious.

Textile wallpaper is splashed with liquids should be dealt with immediately, with the semi-dry white cloth rub a small area, if there is no effect, do not worry, with professional cleaners clean wallpaper, shake spray to stains, cleaning agents were immediately foam, with a scouring pad or cloth to wipe constantly circling, stains suddenly disappeared. If you can not buy a professional wallpaper carpet cleaners can be used instead of scouring agent, with a sprayer will agricultural sprayer spray cleaner dirt area, circling constantly rubbing with a rag, the stain will slowly disappear.
3, pure paper wallpaper
Mainly by grass, bark, etc., and modern high-grade wood pulp processing new natural enhance, color natural, generous, simple, easy to paste technology, not Alice, blistering, no smell, environmentally friendly high-performance, breathable, as European children's rooms earmarked type wallpaper, especially more modern new wallpaper strengthen pulp scrub, anti-static, no dust and other characteristics.

Paper, cloth wallpaper stain can not be washed with water, available eraser. Colored wallpaper on the new oil, can be used to remove the talcum powder, talcum powder on the pad sheets in absorbent paper, then iron the next. If there are bubbles, wallpaper can be broken with the needle surface evolution of gas bubbles, and then needle injection adhesive with a scraper scraping compacted.

The basis for selection of cotton prevention equipment

1. Model Size (prevention productivity size) and regional control scale size.
In general, the effective control of cotton pests once for about three days. An effective amount of equipment service Q:
Q = wt
Where W - machinery service productivity (acres / day);
t - effective prevention and treatment period (days).
Such as manual sprayers Q Hand = 3 × 3 = 9 acres.
Motorized knapsack sprayer duster machine back Q = (80 ~ 100) mu / (day × 3) = 240 ~ 300 acres.
Medium boom sprayer machine in Q = (200 - 300) mu / (day × 3) = 600 ~ 900 acres.
2. Machines spray pattern (including formulation, the amount of spray or mist particles spectrum) and the specific requirements for prevention.
Arid areas can be selected ultra low volume chemical sprayer spray control, such as the selection Knapsack Sprayer Duster with ultra low volume sprinklers or hand-held electric ultra low volume machines. Its spray volume of 100 ml / min or so, you can save a lot of water. Powder can be used in the late cotton, fog alternate Prevention. Choice Knapsack Sprayer Mist Duster with head or dusting parts. Small plots can be hand duster dusting.
3. Cotton plots size, degree of mechanization planning, such as the Jota of roadway, row spacing and other closely related with the choice of models.
Medium and large boom sprayer in cotton fields in the late control, we must consider the roadway cotton, plant height, Jota flatness, low roadway middle interplanting crops, as well as including the entire mechanized planting fertilizer and other agronomic system.
4. Cotton combat different growth models to choose different
Seedling small plots can be manual machines targeted spray, spray using Snap point switch, a small amount of solid cone spray mist nozzle diameter of 0.7 mm and a low volume sprinklers tablets. Large plots available in boom sprayer is equipped with a series of narrow row nozzle slit nozzle as 60. Medium-sized plots available in the late knapsack sprayers Duster, a small boom sprayer operating control more efficient. In the lower part of the plant diseases and insect pests can be directed spraying mist flow to increase penetration. Dorsal pest Knapsack Sprayer Duster can be used to spray swing Pentong way to stir strains airflow leaves; or targeted spray boom sprayer; also manually install the L-shaped duster dusting head, dusting head off the ground about 30 cm for dusting.
5. For more serious insect pest disaster situation with a large outbreak of cotton, in order to quickly control the situation and conditional regions can be sized boom water power sprayer or aerial spray equipment for large area quickly extinguished Prevention.

Spraying pesticides to do preventive measures

1 accurately calculate the dose based on soil and climatic conditions, grass love Nicosulfuron determined amount of medication to the amount of quasi-chemical control area to area medication, accurate dilution, uniform portable sprayers spraying, do not re-spray, spray does not leak, does not arbitrarily increase drug concentration and spraying times.
Two strictly proper spraying of liquid medication scientifically formulated to determine the period, it is necessary to consider the sensitive period of weeds, for good control effect, but also to choose seasonal crops resistant to strong, safe time Xiacha crop spraying . 3-5 leaf stage of corn for resistance Nicosulfuron strongest, safest medication at this time. If because of the weather and other reasons, the 6-leaf stage of corn after the medication, as directed spray, pharmaceutical avoid touching the heart of corn leaves. General 2-leaf stage of corn leaf stage before and 10 after the drug-sensitive, not medication. Meanwhile, the solution should be accurate dilution, mix well before spraying.

3 application techniques to improve the level of strict rules to guide farmers Phytocide poor performance out of the existing old-fashioned manual sprayers, the introduction of good performance, high efficiency, low cost, a new sprayer. Currently there are better performance Shandong Wish Plant Protection Machinery Co., Ltd. produces WS-16P type sprayer and Shandong Huasheng Pesticide Co., Ltd. production Tarzan-18AC backpack sprayers duster machine. As nicosulfuron herbicide is super efficient, re-spray, drip, it is likely to cause local agent concentration is too large to produce injury. In addition, before each medication must ensure that sprayer clean, avoid the other Yaoxie corn injury caused by pesticide residues.

In addition, naphthalic anhydride with corn seed coating can reduce Nicosulfuron with organophosphate insecticides effect caused by the injury.

Hydraulic sprayer working process and composition

Hydraulic able to send the spray atomization and spraying said hydraulic sprayer, whose work is characterized by the liquid pressure, so that the high-speed flow in the spray system, and then the nozzle (atomizer) ejected, suffering from drug liquid internal instability and the frictional resistance between the liquid and the air, then the liquid is atomized, and was sent to the spray target. flower sprayer

Xu are the main tank configuration, filter device, a stirring device, a pump (pump or pump), spray bar, the nozzle, the liquid switch. Liquid storage tank is used, and some also doubles as a storage of compressed air. Filter means for the filter mixed liquid rt, inclusions, to avoid damage pump and spray nozzle orifice clogging. At least three or more motorized sprayer filter device, one tank filler neck, the second is the liquid into the pump before the three before entering the nozzle. The fineness of the filter aperture becomes necessary, as the filter at the aperture of the nozzle orifice diameter not greater than 112, the filter should be sufficient to ensure that the liquid into the liquid supply space. In recent years, the spray volume (L / ha) a reduction in the sprayer Saikawa smaller diameter of the nozzle orifice, the filter aperture becomes smaller accordingly, (changed from 50 to 80 months, or 100 mesh), in order to ensure such a small strainer holes are not clogged liquid in the text, and some sprayer _L A device equipped with self-cleaning unit over, · Use high-pressure liquid from the pump to provide dynamic scour white filter screens, The debris flow by the return line back to the tank directly. Motorized sprayer tank with liquid mixing device to ensure that the concentration of the liquid inside the spraying process has always been consistent. Most pump sprayers equipped with hydraulic mixing method are used, to ensure the stirring effect, m mixed use with the flow amount of liquid (L plus in) should be at least 5% of the tank volume, and should certain Osteoform. To this end, in addition to the main part of the supply pressure of the liquid spray gun, the part of the reflux tank used for mixing.

Pump with rotary pumps and pump two types of living complex. Rotary pump with roller pumps and centrifugal pumps, only use sprayer. Reciprocating pumps piston pumps, piston pumps, diaphragm pumps, etc., in a motor and manual spray jp14, used widely on. With reciprocating pump sprayer is equipped with inlet and drain valves and air chambers, sprayer equipped force on the liquid supply pump [such as reciprocating pumps and roller pumps) and the two devices must be equipped with a safety valve in the spray Shi excess liquid tank when returned. protection spray pressure system. Adjust spring acting on the pressure relief valve on the spray available in different R force. manual sprayer

Hydraulic sprayer spray nozzle is a key component of the liquid. According to different-shaped spray mist, fog nozzles are tapered and scalloped penetration nozzle two kinds.
