Embodiment 1

[0019] The components and contents of the preparation for accelerating the degradation of pesticides in plants are as follows:

[0020] Each 100ml preparation contains:

[0021] Brassinolide: 5 mg

[0022] Abscisic Acid: 0.1 g

[0023] 95% alcohol by mass: 4 ml

[0024] Tween 60 with a mass concentration of 98%: 2 ml

[0025] The balance is water.

[0026] Preparation method: take each component according to the above ratio, firstly dissolve brassinosteroid and abscisic acid in alcohol, add Tween 60, mix uniformly to form a solution, and then mix the solution with water evenly.

[0027] At the 6-leaf stage of Chinese cabbage (variety: Hangzhou Youdonger), take 10 ml of this preparation, add 10 liters of water, mix well, and then spray evenly on the surface of the leaves 5 days before harvesting until they are wet. See Table 1 for the comparison results of the pesticide degradation effect and the control example.

Embodiment 2

[0031] The components and contents of the preparation for accelerating the degradation of pesticides in plants are as follows:

[0032] Each 100ml preparation contains:

[0033] Brassinolide: 20 mg

[0034] Abscisic Acid: 0.5g

[0035] Alcohol with a mass concentration of 95%: 6 ml

[0036] Tween 60 with a mass concentration of 98%: 8 ml

[0037] The balance is water.

[0038] Preparation method: take each component according to the above ratio, firstly dissolve brassinosteroid and abscisic acid in alcohol, add Tween 60, mix uniformly to form a solution, and then mix the solution with water evenly.

[0039] During the fruiting period of cucumber (variety: Jinchun No. 3), take 10 ml of this preparation, add 10 liters of water, mix well, and spray evenly on the surface of the leaves 3 days before harvesting until moist. See Table 2 for the comparison results of the pesticide degradation effect and the control example.

Abstract

The invention discloses a preparation for accelerating the degradation of pesticides in plants. Each 100ml of preparation comprises 5-20mg of brassinosteroids, 0.1-1.0g of abscisic acid, 3-50ml of alcohol with 95% of mass concentration and 2-10ml of tween 60 with 98% of mass concentration, and the rest is water. The preparation of the invention has the advantages of simple fabrication, convenient use, low cost and no side effects. Furthermore, the preparation can remarkably reduce 30%-70% of residues of pesticide in the plants, and reduces the safe interval period in using pesticides for about 3-5 days, meanwhile, the preparation can also improve the resistibility of the plants remarkably, and reduce the usage amount of pesticides. Thus, the preparation is applicable for crops such as vegetables, fruit trees, flowers, tea leaves and the like, and is suitable for popularization and application in vast rural areas of our country.

Description

technical field [0001] The present invention relates to preparations for accelerating the degradation of pesticides in plants. Background technique [0002] Pesticides play an active role in preventing and controlling pests and diseases, removing weeds, controlling human and animal infectious diseases, and improving the yield and quality of agricultural products. The invention and use of pesticides have undoubtedly greatly improved the yield of crops. The negative effects of pesticide residues in food on human health are increasingly revealed. The abuse of pesticides in vegetables and fruits in my country is quite serious. The results of the national supervision and random inspection of product quality announced by the General Administration of Quality Supervision, Inspection and Quarantine in 2000 showed that the problem of excessive pesticide residues in vegetables is prominent: one is that the organic phosphorus residues exceed the standard; Containing a variety of pestic...
