Add pesticides to increase efficacy
In the prevention and control of pests and diseases of crops, a small amount of vegetable oil (cotton seed oil, rapeseed oil, soybean oil, etc.) can be used in combination with pesticides to increase the efficacy of the pesticide. But disabled on vegetables. The method is: Mix the vegetable oil with the pesticide in an 8% ratio. Why does the pesticide refueling have miraculous effects? Vegetable oil can not only function as a petroleum-based surfactant, but also as a good anti-volatility agent, which can make the sprayed liquid evenly cover the surface of the plant and ensure that the pesticide has a longer residual period. Among the synthetic pyrethroid pesticides, vegetable oil is also a finest diluent. The use of vegetable oil as an adjuvant can avoid the occurrence of phytotoxicity to some sensitive crops due to the use of mineral oil. Vegetable oils, when mixed with pesticides, can produce good permeability, allowing the drug to kill the bacteria within the tissue or infiltrate the insect body walls, killing pests and pathogens. In addition, after the vegetable oil is mixed with the pesticide, it has a strong exhibition property, which can increase the coverage of the plants and is not easily washed away by rain, and can still maintain good efficacy after rain. After the vegetable oil is mixed with the pesticide, it also has the characteristics of photodecomposition, which can reduce the strong drift during spraying, overcome the water containing minerals, and weaken the active ingredient of the pesticide. The vegetable oil has strong viscosity and is very suitable for low-volume spraying and super Low volume spray. Experiments have shown that the use of vegetable oil as an adjuvant spray can save one-eighth or even more. It should be noted that: vegetable oil can not be mixed too much, so as to avoid blocking the nozzle due to excessive foam.
