[0029] Correspondingly, the embodiment of the present invention also provides a preparation method of the above pesticide dry suspension concentrate. In one embodiment, the preparation method of the pesticide dry suspension concentrate of the embodiment of the present invention comprises the following steps:

[0030] Step S01: measure the raw materials of each component according to the components contained in the pesticide dry suspension concentrate of the embodiment of the present invention;

[0031] Step S02: Mixing and grinding the raw materials and solvents of each of the above components to obtain a suspension;

[0032] Step S03: drying the suspension to prepare a dry suspension.

[0033] Specifically, the above steps are specifically, the type and content of each component raw material measured in the above step S01 are the same as the type and content of each component described above in the embodiment of the pesticide dry suspension concentrate. In order to save spac...

Embodiment 1

[0042] This example provides a 25% thiamethoxam dry suspension and its preparation method. Among them, 25% thiamethoxam dry suspension contains 12.8 grams of 98% thiamethoxam technical, 1 gram of sodium lauryl sulfate wetting agent, 7.5 grams of lignin dispersion aid, 7.5 grams of disintegrant urea , 1 gram of polyvinyl alcohol, a special additive for flight prevention, 20.2 grams of light calcium, and 0.25 grams of silicone defoamer.

Abstract

The invention provides a pesticide dry suspending agent and preparation and application thereof. The pesticide dry suspending agent is prepared from, by mass, 5-70% of pesticide active ingredients, 1-5% of wetting agent, 1-40% of dispersing agent, 0-20% of disintegrating agent, 2.5-10% of an auxiliary special for preventing flying, 0-0.5% of defoaming agent and 0-30% of filler. The pesticide dry suspending agent is small in average grain diameter, good in dispersing stability and high in suspension rate, and has the advantages of resisting volatilization, resisting drifting and more uniform in fogdrop size. In addition, the preparation process of the pesticide dry suspending agent is easy to control, it is effectively ensured that the prepared pesticide dry suspending agent is stable in performance, production efficiency is effectively improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the fields of pesticide preparations and plant protection, and in particular relates to a pesticide dry suspension and its preparation and application. Background technique [0002] China is a large agricultural country with 1.8 billion mu of basic farmland. Most of the farmland plant protection operations adopt the traditional manual large-capacity spraying method, which is time-consuming, laborious, water-consuming, and has low operating efficiency, pesticide utilization rate and safety. Small plant protection drones are used to spray pesticides for plant protection. Compared with the traditional manual spraying method, the water consumption is less, the spray droplets are small, the penetration of the plant canopy is good, and the spraying is more uniform, which saves time, effort, and Efficient, safe and other advantages. [0003] At present, small aircrafts for plant protection flying and defense mainly include oil-powere...
