Simple pressure sprayer how to do
Utilization of waste Straw and beverage bottle, a kind of simple pressure sprayer. It is pressure sprayer and easy to do, give flowers and water spray is also very suitable. Plastic Straw first two diameter of about 3mm, a Straw with candle flame heating, bent into a 90 degree curved pipe. Find a plastic bottles, unscrew the cap, two holes drilled in the bottle, the two Straw insert cap hole. Two pipe edge required to contact or leave backpack pressure sprayers space to make the nozzle, the cover on the beverage bottle, pressure sprayer is complete. When in use, the bottle cap with Straw unscrew. With the right amount of water (not limited to submerged jet pipe), lid tightly. Hand holding a drink a continuous pressure for a song, can spray water mist. In the process of using, the bottle of water portable power sprayer reduced, if the bottle Straw out of the water, not water, this can be pressure sprayer upside down, so that the Straw as jet pipe, water contact curved pipe as the water spraying pipe, still can continue to.

What would cause injury vegetables
Dilution water used in pesticide
Dilution water used in pesticide different effects on different physical and chemical properties of pesticides, can sometimes improve injury. If hard water is used to dilute EC pesticides could easily lead to injury.
Residual injury
Since long-term continuous use of a single strong pesticide residues, accumulated year after year be sensitive vegetable produce injury.
Drift injury
When the use of pesticides or mist drifting particles diffuse fly around sensitive crops would produce injury. Onion Field garden pressure sprayer spraying of herbicides such as cowpea easy to produce injury.
Not thoroughly cleaned sprayer
Spraying herbicide sprayer, if not thoroughly cleaned and then used for vegetable spray pesticides, herbicides residues in vegetables easy to produce injury.
Resistance factor
Different vegetables, different species, different growth stages of pesticide resistance are different. Brassicaceae, Solanaceae, Gramineae vegetables resistant strong, weak resistant leguminous vegetables, melons and vegetables Resistance of the weakest. Cabbage on copper fungicide sensitivity for carbaryl sensitive melons, melons, beans can not touch the 2,4-D herbicide. In addition, vegetables or plants at different growth stages of drug resistance in different parts of victims of different capacities, such as tender young vegetables and vegetable section, flowering resistant weak, prone to injury. Waxy or hairy leaves more vegetables is not easy to produce injury.
Environmental Factors
Hot spraying easy to produce injury, it is not easy spraying temperature, especially in hot weather do not knapsack power sprayer spraying when the temperature is high noon. Some pharmaceutical use in rainy weather prone to injury, such as rain, humid conditions using Bordeaux mixture prone to injury. Strong sunlight prone to injury. Less sandy soil and organic vegetables grown in soils prone to injury, followed by loam, clay soil organic matter and more difficult to cause injury.
