Problems solved by technology

Since the 1990s, foreign pesticide companies have developed several new insecticides that have special effects on diamondback moths, such as abamectin, fipronil, AC303630, and detox, but these insecticides are expensive and have greatly increased The cost of prevention and control is out of reach for the vast majority of vegetable farmers in China
And the single use of these pesticides will also lead to the development of resistance to these pesticides
[0003] In order to reduce the control cost of vegetable pests, delay the development of pest resistance to existing excellent insecticides, and avoid the resistance caused by single use of insecticides, it is urgent to develop chemical compounds with high efficiency, low toxicity and low price for diamondback moth. preparation

Embodiment 1

[0016] The preparation of the 36% maa emulsifiable oil of embodiment 1

[0017] formula:

[0018] Malathion 35.88%

[0019] Abamectin 0.12%

[0020] Farm Milk 0201 10%

[0021] Xylene make up to 100%

[0022] Preparation method: Weigh avermectin and dissolve it in an appropriate amount of xylene, stir evenly, add malathion, then add Nongru 0201, and stir until the original drug is completely dissolved.

Embodiment 2

[0023] Example 2 36% Ma. A EC Indoor Bioassay Report

[0024] 1. Research purpose

[0025] The toxicity of two insecticides, malathion and avermectin, to Plutella xylostella was determined in different proportions, and the optimal proportion of Ma. A EC for controlling Plutella xylostella was determined.

[0026] 2. Materials and methods

[0027] 1. Drugs to be tested

[0028] 45% malathion emulsifiable concentrate: product of Shandong Dezhou Pesticide Factory.

[0029] 86% malathion crude oil: product of Shandong Dezhou Pesticide Factory.

[0030] 1.8% Abamectin EC: a product of the Experimental Pharmaceutical Factory of Beijing Agricultural University.

[0031] 2. Test insects

[0032] In August 1996, pupae of Plutella xylostella collected from a vegetable field in the suburbs of Shanghai emerged indoors and laid eggs on fresh potted radish seedlings. The larvae ate radish seedlings until they pupated. The test insects were not exposed to any insecticides after being ha...

Abstract

A composite agricultural chemical in the form of emulsified oil or suspension for preventing and elimianting plutella xylostella contains abamectin and malathion in the ratio of 1:(100-1000). Its advantages are high effect and low poison.

Description

Technical field: [0001] The invention relates to a malathion-abamectin pesticide composition. Background technique: [0002] Diamondback moth is a major pest of cruciferous vegetables worldwide. For a long time, the control of diamondback moth has mainly relied on chemical pesticides. Due to the irrational use of a large number of insecticides, the diamondback moth has developed high resistance to almost all insecticides developed before the 1990s. Since the 1990s, foreign pesticide companies have developed several new insecticides that have special effects on diamondback moths, such as abamectin, fipronil, AC303630, and detox, but these insecticides are expensive and have greatly increased The cost of prevention and control is out of reach for the vast majority of vegetable farmers in China. And the single use of these pesticides will also lead to the development of resistance to these pesticides. [0003] In order to reduce the control cost of vegetable pests, delay th...
