Peanuts are common oil crops in our lives and are the vegetables we eat regularly. Friends who grow peanuts certainly hope that peanuts can increase production and obtain more economic benefits. This article will introduce the use of pesticide controlled slow release technology to increase peanut yield.
To control peanut pests and diseases, it is generally necessary to apply pesticides 2-3 times during the peanut growth cycle. The reporter recently learned from the Anhui Academy of Agricultural Sciences Plant Protection Institute that the phoxim microcapsule suspension agent developed by the institute has overcome the pesticide controlled release technology. It can be applied only once when peanuts are planted, and it can control the damage of various underground pests such as cockroaches during the whole growth period of peanuts, which is 20%-40% higher than that of conventional pesticides.
It is understood that the secret of controlled release of the pesticide is a large number of "plastic pellets" with a diameter of 1-50 microns suspended in the pesticide liquid. The pesticide phoxim is infused into these small balls which are invisible to the naked eye with advanced technology. After adding water and mixing into the soil, it will not be released at 8 degrees Celsius or below, and the release amount below 20 degrees Celsius will be less than 20 degrees Celsius. The speed begins to accelerate, and the release is faster than 30 degrees Celsius. After the peanuts are sown in April and mid-April each year, the soil temperature is low and there are no pests and diseases. At this time, the amount of pesticide released is very small. When the fruit matures in the middle and late July, the soil temperature is high, which is a high incidence of pests and diseases, and the release rate of pesticides is accelerated, which is the effect of killing pests.
The phoxim microcapsule suspension agent not only solves the problem of controlled release of pesticides, but also replaces organic solvents with water, reduces production costs, has low toxicity and is more environmentally friendly. Experts say that after the release of the active ingredient in the phoxim microcapsules in mid-July, it can be degraded into water and carbon dioxide in the soil in just 20 days, and this is about a month away from the peanut harvest. No pollution to soil and peanuts.
