Embodiment 1

[0055] Embodiment 1: The present invention is used for the pesticide A of unmanned aerial vehicle application

[0056] (1) the degree of alcoholysis is 88%, and the polyvinyl alcohol raw material that average molecular weight is 2-4 ten thousand is dissolved in water, and the percentage by weight of polyvinyl alcohol in the obtained glue is 30%;

[0057] (2) The glue was left to stand for defoaming for 5 hours, poured into a mold for molding, and then demolded after drying at 100°C for 4 hours to obtain an open capsule; after testing, the thickness of the polyvinyl alcohol film on the outer layer of the capsule was 1500 μm , the tensile strength is 5MPa;

[0058] (3) 100g of agar was added with water and stirred and dissolved at 50°C, evaporated and concentrated to 60% (w / w) at this temperature, cooled to 35°C, added 286g of abamectin and 23.8g of activated carbon (particle size 200-400μm ) into a gel composition, put the gel composition into the cavity of the capsule, fill i...

Embodiment 2

[0060] Embodiment 2: The present invention is used for the pesticide B of UAV application

[0061] (1) 150g alcoholysis degree is 95%, the average molecular weight is the polyvinyl alcohol raw material of 40,000-60,000, 2.7g butyl benzyl phthalate, 0.7g cross-linked polyvinylpyrrolidone and 7g polyoxyethylene polyoxypropylene Add water to alcohol amine ether until 1000g is dissolved to obtain glue;

[0062] (2) Leave the glue to stand for defoaming for 6 hours, pour it into a mold and mold it, dry it at 50°C for 10 hours, and demould it to obtain an open capsule; after testing, the thickness of the polyvinyl alcohol film on the outer layer of the capsule is 500 μm , the tensile strength is 4MPa;

[0063] (3) 100g of agar was added with water and stirred and dissolved at 50°C, evaporated and concentrated to 50% (w / w) at this temperature, cooled to 30°C, and 213g of trichlorfon (dimethyl-(2,2,2 - Trichloro-1-hydroxyethyl) phosphate) powder and 12.77g starch are mixed to form a...

experiment example

[0068] Use the same type of UAV to load pesticides A-C for pesticide application. The objects of application are three farmlands with similar geographical locations and an area of ​​20 mu. Among them, pesticides A and B are sprayed while irrigating. Track and observe the application process, determine the application time, and observe the efficacy.

[0069] (1) Application process:

[0070] Ⅰ. Pesticide A: Before spraying, divide each acre into four areas equally, and drones only apply pesticides at the center of each area. After the pesticide falls to the ground, the water-soluble film on its outer layer is dissolved and damaged by water, and the gel composition is sprayed out from the damaged part. With the spraying of the composition, the damaged part cracks gradually, and finally cracks completely and sprays the drug around. The spraying distance is 5-10 meters, and the sprayed gel composition is dissolved and diluted with water, and is blocked by crops during the sprayin...

Abstract

The invention belongs to the technical field of pesticides, and relates to a pesticide applied through an unmanned aerial vehicle. The pesticide is prepared from water-soluble film, gas and a gel composition; the water-soluble film forms a sealed capsule body which is filled with the gel composition and the gas, and the internal pressure of the capsule body is greater than the external pressure of the capsule body. The invention further relates to a preparation method of the pesticide. When the pesticide is used, the loading capacity of one-time effective components of the unmanned aerial vehicle is large, and the frequencies of repeated pesticide adding are reduced; pesticide spraying is completed by means of the spray force of the pesticide in the capsule body, the unmanned aerial vehicle does not need to conduct large-area spraying, the effect can be achieved by only putting the pesticide on multiple points, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, relates to a pesticide applied by a drone, and also relates to a preparation method thereof. Background technique [0002] Pesticide spraying is very important to the growth of crops. Traditional pesticide spraying is manual spraying with low work efficiency. Later, a method of using ground machinery to spray pesticides appeared, but this type of machinery often has special requirements for farmland plowing roads. In recent years, small drones have appeared for pesticide spraying operations, which have high spraying efficiency and high utilization value. [0003] At present, the pesticides sprayed by small UAVs are mainly loaded diluted liquid medicines or separated medicine powders and water. Since small UAVs can only load a small amount of effective pesticides at a time, UAVs often need to take off and land repeatedly and load pesticides repeatedly during continuous large-scale spraying op...
