Problems solved by technology

[0003] The first object of the present invention is to provide a carrier of pesticides, to solve the problem of degradation of pesticides in the prior art after application, or to reduce the control effect due to dilution, and at the same time, it can make the residues of pesticides on the surface of crops more effective. It can be easily removed with little water washing; the second object of the present invention is to provide the method of using this carrier

example 1

[0012] The test area is an energy-saving solar greenhouse, the test crop is cucumber, and the test pesticide is the fungicide chlorothalonil. Pesticide residues were determined by SP3420 gas chromatograph according to GB14878-94 standard.

[0013] The same greenhouse is divided into three equal areas along the length direction, one of which is a blank control area for water spraying, the second is a control area for spraying chlorothalonil according to the prior art, and the third area is for spraying and the second area. The same amount of chlorothalonil in two areas and the test area of ​​the pesticide eliminating agent of the present invention, the particle size of the PAL powder added in the test is 100 mesh to 400 mesh, and the weight ratio of the added PAL material to the chlorothalonil liquid is 7 to 4 : 1. The test results are shown in Table 1, Table 2 and Table 3 respectively.

[0014] It can be seen from Table 1 that after adding PAL powder to the pesticide, the do...

example 2

[0023] The test area is a plastic greenhouse, the test crop is oily cabbage, and the test pesticide is the insecticide omethoate. Pesticide residues were determined by SP3420 gas chromatograph according to GB14878-94 standard.

[0024] Table 4 Determination of insect control effect of rapeseed cabbage

[0025] As can be seen from Table 4, after adding PAL in the pesticide sprayed, the control effect to aphids can reach 93.85% on the 5th day of spraying, which is 6.83 percentage points higher than the control effect of simply spraying dimethoate; The control effect on aphids reached 94.42% on the 10th day afterward. But in the control area of ​​simply spraying dimethoate, its control effect on the 10th day has dropped from 87.2% on the 5th day to 82.47%, indicating that its insecticidal effect has diminished. This test has fully demonstrated that PAL powder can slowly release pesticides and maintain the characteristics of killing pests efficiently for a long time. T...

Abstract

The present invention discloses one kind of pesticide scavenger and its usage. The pesticide scavenger is one kind of pesticide carrier made of PAL material in granularity of 40-400 mesh. The PAL material in certain amount is mixed with pesticide liquid and the mixture is then spread or sprayed onto crops.

Description

technical field [0001] The present invention relates to a pesticide carrier and a method for using the carrier. More precisely, the present invention is a substance that is mixed with pesticides and applied to crops together, which can release the pesticides slowly, improve the insecticidal or bactericidal effect of the pesticides, and make the pesticides easy to clean and remove. The method of use of the substance. Background technique [0002] Utilizing pesticides to prevent and treat crop diseases and insect pests is a commonly used measure in the prior art. But the use of pesticides also brings some side effects. Such as pollution and poisoning of the environment. After the application of pesticides, due to the effect of natural factors, such as light, rain, etc., the pesticides will be degraded or further diluted, resulting in a decrease in the control effect of the pesticides. At this stage, multiple application of pesticides is used to solve this problem, but this ...
