Problems solved by technology

Tetranychid mites broke out on crops such as strawberries, eggplants, cucumbers, and beans in Changping, Daxing, and Fangshan in Beijing. Producers used various pesticides to prevent and control them, but with little effect. Those with serious damage caused crops to be pulled early and yields decreased. , or even fail

Embodiment 1

[0015] 30% Bifenazate Humic Acid Suspension Concentrate

[0016] Bifenazate 22%

[0017] Humic acid 8%

[0018] Micro-fertilizer (Zinc EDTA: Iron EDTA: Magnesium Sulfate=2:1:1) 4%

[0019] Nonylphenol polyoxyethylene ether phosphate 8%

[0020] JFC3%

[0021] Ethylene glycol 5%

[0022] Xanthan gum 0.3%

[0023] Make up to 100% with water

[0024] The various components are mixed together, sheared and dispersed first, and then ground in a sand mill until the particle size of the active ingredient is less than 3 μm. The addition of nonylphenol polyoxyethylene ether phosphate, JFC, and xanthan gum not only helps to make the dosage form, but also maintains the stability of the dosage form, helps storage and transportation, and ensures the efficacy of the drug.

[0025] Various auxiliary agents, carriers, etc. added in the present invention are all products sold in the market, and are commonly used auxiliary agents in pesticide production.

Embodiment 2

[0030] In order to clarify the control effects of bifenazate and foliar fertilizers on spider mites and diseases when used alone or in combination, a large number of field experiments were conducted in Beijing in 2014.

[0031] Experiment 1: Field efficacy test of 30% bifenazate·humic acid suspension against Tetranychus urticae and powdery mildew

[0032] Test time: November 3, 2014.

[0033] Test site: Xiaotangshan Strawberry Planting Base, Changping District, Beijing.

Abstract

The invention relates to a compound pesticide composition which is mainly used for preventing and treating pest mites and improving crop growth vigor and adverse resistance. The compound composition comprises bifenazate and foliage fertilizer, wherein the weight ratio of the bifenazate to the foliage fertilizer is (5-50):(1-20), and the bifenazate and the foliage fertilizer account for 10%-70% of the total weight of the composition. The compound composition is a suspending agent. The compound composition is used for preventing and treating various pest mites, enhancing plant adverse resistance, guaranteeing the crop yield and the like.

Description

technical field [0001] The invention relates to a pesticide composition containing bifenazate and foliar fertilizer, which is mainly used for preventing and controlling various pest mites and inducing stress resistance of crops. Background technique [0002] Acarids are one of the main pests that harm crops. In my country, spider mites represented by Tetranychus urticae have gradually become one of the important pests of fruit trees and vegetables. Due to the characteristics of the mite's small size, short generation cycle, and high reproduction rate, and under the influence of special environmental factors in the current greenhouse, many crops are harmed by the spider mite. Tetranychid mites broke out on crops such as strawberries, eggplants, cucumbers, and beans in Changping, Daxing, and Fangshan in Beijing. Producers used various pesticides to prevent and control them, but with little effect. Those with serious damage caused crops to be pulled early and yields decreased. ...
