preparation example Construction

[0044] Correspondingly, the embodiment of the present invention also provides a preparation method of the above pesticide dry suspension concentrate. The preparation method of the pesticide dry suspension of the embodiment of the present invention comprises the following steps:

[0045] Step 1: Weigh each component raw material respectively according to the components contained in the pesticide dry suspension concentrate of the embodiment of the present invention;

[0046] Step 2: Mix the raw materials of each component weighed in step 1 with water at a weight ratio of 3:7-1:1, stir evenly, and perform sand milling to obtain a suspension with a particle size of D50<2μm liquid;

[0047] Step 3: The suspension described in step 2 is spray-dried using a spray dryer under the condition that the inlet hot air temperature is 120-150°C and the outlet hot air temperature is 60-90°C to prepare the pesticide dry suspension .

[0048] The weight ratio of each component raw material an...

Abstract

The invention relates to a pesticide dry suspension agent suitable for flight control and a preparation method and an application thereof. The pesticide dry suspension agent comprises, by mass percent, 10-80% of pesticide active ingredients, 1-5% of a wetting agent, 2-8% of a dispersing agent, 1-10% of fatty acid ester ethoxylate, 0-1% of a defoamer, and 0-80% of a carrier. The pesticide dry suspension agent provided by the invention has the advantages of small average particle size, good dispersion stability and high suspension rate. In particular, the fatty acid ester ethoxylate used in theformula can greatly reduce the volatility and drifting performance of pesticide spray droplets, which is very suitable for use in unmanned aerial vehicle spray and improves the accuracy and control effect of spraying. In addition, the preparation process of the pesticide dry suspension agent of the invention can be easily controlled, effectively improves the production efficiency and reduces the production cost.

Description

technical field [0001] The present invention relates to the fields of pesticide formulations and plant protection, in particular to a pesticide dry suspension, its preparation method and its use in drone spraying. Background technique [0002] At present, pesticides have become an important means of controlling crop diseases, insect pests and weeds. In recent years, the level of scientific and safe use of pesticides has been continuously improved, especially in terms of improving pesticide application equipment, organizational methods, and use techniques to scientifically promote precision pesticide application, improve the utilization rate of pesticides, and achieve the goal of efficient damage control. The traditional pesticide plant protection operation adopts artificial large-capacity spraying method, which is time-consuming, laborious, large water consumption, low operating efficiency and low pesticide utilization rate. This mode is gradually replaced by small plant pr...
