Problems solved by technology

The traditional methods for removing pesticides on the surface of agricultural products include: washing with water, washing with alkaline water, washing with detergent, cleaning and peeling, etc. The disadvantages of these methods are: long processing time, serious waste of water resources, and long-term processing does not remove the clean surface of fruits and vegetables. pesticides, the removal efficiency of pesticides is low, and the nutrients of fruits and vegetables will be lost, and even cause secondary pollution

preparation example Construction

[0031] The preparation method of the composition for degrading pesticide residues of the present invention is conventional mixing in the field, weighing each component by weight, and mixing.

[0032] The present invention also provides the application of the composition for degrading pesticide residues of the present invention in reducing pesticide residues in crop products.

[0033] The composition for degrading pesticide residues of the present invention can reduce pesticide residues in crops before harvest, especially for fruit crops, can reduce pesticide residues by more than 30%, has a stable effect, and can not only degrade pesticide residues on the surface of crops, but also reduce The amount of pesticide residues contained in crops. Among them, preferably the crops are peppers, cucumbers, tomatoes, eggplants or bitter melons. The composition for degrading pesticide residues of the invention can reduce common pesticide residues in the field, especially the pesticide re...

Embodiment 1

[0037] Take 10kg of seaweed polysaccharide, 1kg of rare earth nitrate, 1kg of gibberellic acid, add 1kg of sodium lignosulfonate and 1kg of sodium lauryl sulfate, mix well, make up to 100kg with anhydrous sodium sulfate, and make a soluble powder.

[0038] When used, it is diluted with water to an active ingredient concentration of 21 ppm. After 72 hours of pesticide application, it is sprayed on the foliage and fruit organs of the pepper, and the sprayed water is used as a blank control. After the capsicum was matured, its yield was measured, and it was found that compared with the clear water control, the capsicum yield had no obvious change, indicating that the composition would not affect the efficacy of the pesticide. Using liquid chromatography and its combination method to measure the pesticide residues in capsicum fruit, it is found that compared with the application of clear water, the pesticide residues are reduced by 40.28%, indicating that the composition of the inv...

Embodiment 2

[0040] Take 1 kg of seaweed polysaccharide, 1 kg of rare earth nitrate, 1 kg of gibberellic acid, add 1 kg of sodium lignosulfonate and 1 kg of sodium lauryl sulfate, mix well, make up to 100 kg with potassium nitrate, and make a soluble powder.

[0041] When used, it is diluted with water to an active ingredient concentration of 40 ppm. After 72 hours of pesticide application, the cucumber foliage and fruit organs are sprayed, and the sprayed clear water is used as a blank control. After the cucumber is ripe, its yield is measured, and it is found that compared with the clear water control, the cucumber yield has no obvious change, indicating that the composition will not affect the efficacy of the pesticide. The pesticide residues in cucumber fruits are measured by liquid chromatography and its combined method, and it is found that the pesticide residues are reduced by 37.6% compared with the application of clear water, indicating that the composition can stably reduce the pe...

Abstract

The invention relates to a composition capable of degrading pesticide residue and an application of the composition capable of degrading pesticide residue, and belongs to the technical field of crop cultivation. The composition capable of degrading pesticide residue provided by the invention comprises the following active components in parts by weight: 1 part of algal polysaccharides, 0.05-20 parts of rare earth, and 0.05-20 parts of gibberellic acid. According to the composition capable of degrading pesticide residue, under the premise that the pesticide effect is not influenced, the pesticide residue quantity in the crop products before harvest can be stably and greatly reduced, the pesticide residues on the surface of agricultural products can be removed, the pesticide residue quantity of agricultural products can be reduced, and the food security of the crop product in the market is guaranteed; the composition capable of degrading pesticide residue is prepared by using the conventional raw materials, and the preparation method is simple and low in cost.

Description

technical field [0001] The invention relates to a composition for degrading pesticide residues and an application thereof, belonging to the technical field of crop cultivation. Background technique [0002] The use of chemical pesticides has greatly promoted the development of modern agriculture, restored a large number of losses caused by diseases and insect pests for agricultural production, and greatly improved the labor efficiency and mechanization degree of agricultural production, playing a role in the modernization of agricultural production. immeasurable effect. But at the same time, pesticides are also one of the important factors affecting the quality and safety of agricultural products. The pesticides used in the production of agricultural products are mainly organophosphorus pesticides, organochlorine pesticides, carbamate pesticides, pyrethroid pesticides, etc. Consumption of products with excessive pesticide residues can lead to acute poisoning, especially or...
