Orchards using glyphosate should pay attention to several issues

Glyphosate is a highly efficient, low toxicity, broad-spectrum herbicide pollution. In recent years, with 10% glyphosate controlling weeds in orchards, and achieved good results. Started one week after using glyphosate markedly ,10-15 parts dry death on earth, a month or so underground brown rot, weed effect of 100%, a drug can reach extermination purposes. But orchards using glyphosate herbicide, should pay attention to the following questions:
1, pay attention to the quality of spraying. Herbicide Glyphosate is the contact green organizations that exert cytotoxicity. Therefore, the requirements of spray nozzles when spraying down weed liquid sprayer evenly thoughtful as close as possible to prevent spray mist drift on fruit tree branches to avoid injury. In particular, sensitive to glyphosate apricot, prone to injury, therefore, apricot using glyphosate more must be cautious.
2, note that according to weed species to determine the amount of glyphosate. Weeds to glyphosate due to various different sensitivities, so different dosage. On annual weeds such as crabgrass, pigweed, barnyardgrass, goosegrass, foxtail, etc., the amount per acre with 10% glyphosate 500-700 ml; against plantain, small canadensis, Commelina per acre you need to 800-1000 ml; against perennial weeds such as Imperata, reeds, thorns vegetables, alkali grass, etc., required to 750-1000 ml per acre. According to the above dosage, dosage watered 20-30 kg per acre for grass targeted spray can. If spraying detergent added 50 grams, 150 grams of diesel, mixed evenly sprayed herbicide force can be increased 1-3 times.
3, note that according to the different periods of medication. Suitable period of use of glyphosate in weed seed growing period prior to flowering period of time, spraying premature, because weed leaves smaller, less affected by the dose, the less weed root tissues damaged affect the herbicidal effects; spraying too late, ie reducing the herbicidal effect and the need to increase the dose and increase costs.
4, glyphosate corrosive to metal, should be kept in the storage and use of the use of plastic containers. After plastic sprayer spraying glyphosate, the sprayer must be repeatedly washed several times with alkaline water, then rinse with water, otherwise the ban to other fruit or other crops sprayed with pesticides.

Scientific control of soybean aphids

Soybean aphid pest commonly known as tired , honey worms. Mostly concentrated in soybeans growing point , parietal , young surface of leaf , sucking sap hazards. Cause leaf curl, dwarf plants , reducing yields , but also spread the virus disease, resulting in cuts and reduced quality . This insect six months late emergence in soybean fields , high temperature and drought when serious harm.

Soybean aphid reproductive capacity is large, a female can reproduce 50-60 , in conditions suitable cases, a small aphid after about 4-5 days to calving, year on soybean can multiply 15 generations .

Soybean aphids have four times annual migration diffusion peak ; 1st in soybean seedling stage , the second is to appear in early June , the 3rd appeared in mid-July, 4th in early September . Should generally be in early July to prevent and treat the most appropriate.

Control methods: chemical control -based, with 40% Dimethoate EC 800 times , or 40% omethoate EC 1000 times .agricultural sprayers 10% permethrin EC bromofluoroacetate 15-20 ml per 667 square meters , 50% pirimicarb WP 10 grams per 667 square meters , watered 40-50 kg spray.

Soybean pod borer prevention

Soy bean borer is a small bite bloodworms . Larvae bore into the pods , bite the tender bean pods can be eaten half granule , reducing yield and quality . This worm one generation to the old larvae overwinter in cocoons ground beans . 2nd year in late July into a pupa and moth flew pods spawning more than 7- August rainfall , soil moisture , is conducive to happen.

Control methods:

( A ) agricultural control . Selection of insect-resistant varieties, crop rotation, timely harvest , timely back yard .

( 2 ) chemical control. With 5% phorate granules 750-1000 grams mixed with soil 10 kg , 10 August , sprinkle in the field , every four ridge sprinkle a ridge , or 80% dichlorvos ,bottle sprayer  667 square meters with 100 ml each , the Baptist dipped 20 cm long sorghum or corn stalk stalk 50 every five ridges inserted a ridge , every 7-8 insert a step .

Purchase of transport and storage of pesticides

A pesticide by the use of units designated person certificate purchase. Care must be taken when buying pesticides pesticide packaging to prevent leaking. Note pesticide product name, active ingredient, date of manufacture, use, etc., failure to identify clear and quality use of pesticides inaccuracies.

2, the transport of pesticides, agricultural sprayers should first check whether the packaging is intact and found a leak, rupture, the application of the provisions of the repackaged material transport, and timely and properly handle the quilt contaminated ground transportation of packaging materials. When handling pesticides gently.

3, pesticides must not food, vegetables, fruits, food, daily necessities and other hybrid or blended.

4, pesticides should be concentrated on the production team, set up job group or professional team dedicated libraries, bottle sprayer special cabinets and special custody, not household saving. Doors and windows should be strong, better ventilation, doors, cabinets to be locked.

5, pesticide registration procedures should be established and out of the warehouse, not allowed to freely access.

Proper use of insect virus pesticides

Insect virus pesticides on specific insect virus artificially propagated, collection, purification, processing, and are environmentally friendly pesticides. When used to note the following:

1, available manual sprayers, mist machines and other used equipment for spraying spraying.

2, insect larvae 1-3 instar is the best medication, parasites larger effective longer.

3, select cloudy or spraying after the sun goes down, avoid direct sunlight at noon affect the efficacy, and can not be mixed with alkaline pesticides.

4, the water dispersible granules mu less, to ensure the efficacy, dispensing time by way of secondary dilution, the first mother liquor is made, together with sufficient water to prepare a hand held sprayer spraying liquid.

5, the user in order to improve the overall control effect and to rid of other pests, and crop control object can be added according to chemical pesticides.

Promotion of new agricultural technologies to boost agricultural production

A "change" to see farming: In conventional mining, or cattle farming labor day, but 0.3-1 acres, while also spending a lot of labor to complete raking, and other follow-up work due to broken; Today, effort, labor, money micro-farming Machine gradually became the protagonist of autumn plowing, plowing harrow a successful, very convenient. Since 2005, Sichuan Tongjiang County Area recruit new types of marketing Tiller 98, the annual plowing an area of ​​7200 acres.

Two "change" Look field management: the past, the main use of manual weeding or hand sprayer plant protection, time-consuming; recent recruit Tongjiang County, Sichuan Province Area of ​​motorized sprayer has a significant increase in the amount of the agreement mechanical plant protection area of ​​3260 mu / years.

Three "change" look harvesting threshing: In the past, either rice or wheat harvest are cut ear and then resort to the use of artificial field awkward, very few farmers with tractors Tractors grind field; vigorously promoted in recent years, the entire chip area motorized thresher, motorized threshing machine has basically reached households Ping units, semi-mechanized harvesting rice and wheat threshing rate of about 70%.

Four "change" look crop stubble treatment: the past,sprayer even after wheat and rice harvest artificial mowing, and dried before ignition burned, time-consuming and polluting the environment; Now, after harvesting crops or directly Tiller chopped straw shredder will also field buried, neither pollute the environment and increased soil organic matter, and fertilize the soil fertility.

Five "to" look on the utilization of fallow fields: In recent years, as national agricultural support policies in place to help farmers, but also farm help, the majority of farmers enthusiasm greatly improved. Now, rice uncollected before, we put on the early dry paddy field, to be harvested after the busy planting canola, spot wheat, vegetables. If in the past, many farmers harvest rice on the land would be reluctant to busy, or direct water to make winter paddy field, or simply turn a blind eye abandoned.

Six "change" to see the rural industrial structure adjustment: promotion of new farm machinery to promote a large number of Tongjiang County, Sichuan Province recruit Area agriculture, pressure sprayer forestry, animal husbandry, and the healthy development of industries and the transfer of rural surplus labor force of new outing more than 1,200 workers, large agricultural machinery, grain, vegetables, large, pig large number of relatively large increase.

Spraying pesticides job the right way

Significantly increased over recent years, crop pests, pesticide use increased, many farmers in field operations has formed a fixed manner. But from a scientific point of view, farm sprayer pesticides, there are still some errors:

First, the front of the body, "the" word swinging spray. Disadvantage is that the front spraying, people in the drug environment sprayed forward, likely to cause pesticide poisoning. Further, when spraying herbicide closed, easy uniform spray, artificial membrane damage after treading to reduce the control effect. Sprayer should be changed right in front of "the" word of swing sideways "s" word swing. Motorized spraying and spraying herbicides should be taken parallel advance spray.

Second, the large droplet spray. Make spray uneven, particularly those affecting tag insecticide control effect. Large liquid droplet spray is also easy to cause the loss of plants low, the waste is more serious, you should try to use a good spray atomization performance, the use of spray holes tablets, a small droplet spray evenly.

Third, the jet "target" crops. Direct spray sprayer can be used generally, and motorized sprayer to mist type, direct spray will greatly reduce the work efficiency, can not be fully motorized weed killer sprayer good atomization characteristics of high efficiency. Sprayer job the right way should be 20 cm above the crop, spray drift downwind implementation.

Fourth, the liquid sprayed from dripping on the extent of the blade. According to scientific determination of liquid drops on the leaves, the liquid precipitation was only 50% of the maximum amount of precipitation can not maximize the efficacy and caused a lot of pesticide waste. It should be evenly sprayed, try not to have liquid dripping.
