A kind of functional auxiliary agent for hot fog machine and its preparation and use method

Abstract

The invention discloses a functional auxiliary agent for a hot fog machine and its preparation and use method. The mass percentage of paraffin oil in the auxiliary agent is 75-94.5%, the mass percentage of a surfactant is 5-20%, and a hot fog density regulating substance The mass percentage is 0.5‑5%. The preparation method is as follows: adding surfactant into paraffin oil, stirring evenly, adding heat fog density regulating substance to prepare oil suspending agent, filtering to remove residue to obtain finished product. The method of use is: add 30-50 mL / 667mL of functional additive 2 Fully mix with fungicides or insecticides and pesticides in formulations such as emulsifiable concentrate, water emulsion, suspoemulsion, suspension, etc., press 300‑500mL / 667m 2 Supplement the amount of water to prepare emulsion, and use a hot fog machine for hot fog spraying to prevent and control crop diseases and insect pests.

Description

technical field [0001] The invention relates to the technical field of high-efficiency application of pesticides, in particular to a functional auxiliary for a hot fog machine and a preparation and use method thereof. Background technique [0002] In recent years, with the adjustment of planting structure and the change of climatic conditions, crop diseases and insect pests have become more and more serious, often showing the characteristics of sudden, explosive and widespread occurrence. The occurrence of pests and diseases is becoming more and more serious, not only causing significant yield loss, but also seriously affecting the quality of agricultural products. At the same time, with the acceleration of urbanization, rural labor resources are increasingly lacking. The traditional spraying control method is labor-intensive, time-consuming, and labor-intensive. Area control. When ordinary sprayers spray pesticides, only about 1 / 3 of the amount applied reaches the leaves ...

AI Technical Summary

Problems solved by technology

The traditional hot mist spraying technology is mostly used for the prevention and control of forest diseases and insect pests. The fuming agents used are mostly petroleum products such as diesel oil. Without special treatment, the hot fog sprayed by the hot fog machine during the spraying process has a low density. , easy to diffuse into the upper layer into the atmosphere, and easy to escape with the wind, resulting in a decrease in the utilization rate of pesticides, unstable control effects, and drift pollution of pesticides. At the same time, diesel and other petroleum products contain more aromatic rings. There are also certain risks to the environment in the process
