Description

an insecticidal composition

technical field

The invention relates to a pesticide composition, in particular to an insecticidal composition containing phthalamide compounds and emamectin benzoate or abamectin.

Background technique

The cyano-containing phthalamide insecticide compound is an insecticide independently developed by our company. The test code: ZJ4042, the molecular formula: C ₂₂ H ₁₇ ClF ₇ N ₃ O ₂ , the relative molecular mass: 523.83, and the chemical name is : 3-Chloro-N ¹ -(2-methyl-4-heptafluoroisopropylphenyl)-N ² -(1-methyl-1-cyanoethyl)phthalamide.

Has the following structural formula (I)

The insecticidal activity of this compound is basically equivalent to that of the recently developed flubendiamide. Flubendiamide, the common name in English (flubendiamide) was developed by Nippon Norochemical Co., Ltd., and its chemical name is 3-iodo-N-(2-methylsulfonyl-1,1-dimethylethyl-N-{4 - "1,2,2,2-Tetrafluoro-1-(trifluoromethyl)ethyl-o-tolyl}phthalamide, molecular formula: C ₂₃ H ₂₂ F ₇ N ₂ O ₄ , is a new type Phthalamide insecticides activate the intracellular calcium release channels of ryanodine receptors, leading to uncontrolled release of stored calcium ions, and are currently one of the few insecticides that act on ryanodine receptors in insect cells. The compound has broad-spectrum control effect on lepidopteran pests, has no cross-resistance with existing insecticides, and is very suitable for the control of pests resistant to existing insecticides.

Abamectin (Abamectin) is a macrolide disaccharide compound with a molecular formula of C ₄₉ H ₇₄ O ₁₄ and a chemical structural formula as follows (II):

Abamectin is a natural product isolated from soil microorganisms. It has contact and stomach poisoning effects on insects and mites, and has a weak fumigation effect without systemic effect; it has a strong penetration effect on leaves and can kill the epidermis pests, and the residual effect is long. It does not kill eggs. Its mechanism of action is different from general insecticides in that it interferes with neurophysiological activities, stimulates the release of r-aminobutyric acid, and r-aminobutyric acid has an inhibitory effect on the nerve conduction of arthropods, and acarids, nymphs and insects are related to The larvae will appear paralyzed after contact with the drug, do not move or eat, and die after 2 to 4 days. Its lethal effect is slower because it does not cause rapid dehydration of the insects. However, although it has a direct killing effect on predatory and parasitic natural enemies, because there are few residues on the plant surface, the damage to beneficial insects is small, and the effect on root-knot nematodes is obvious.

Emamectin benzoate (Emamectin benzoate), chemical name 4″-epi-methylamino-4″-deoxy avermectin B1 benzoate (at least 90% 4″-epi-methylamino-4″ - deoxyavermectin B1a and up to 10% 4"-epi-methylamino-4"-deoxyavermectin B1b benzoate mixture). Its molecular formula: C ₄₉ H ₇₅ NO ₁₃ , C ₇ H ₆ O ₂ (B1a); C ₄₈ H ₇₃ NO ₁₃ , C ₇ H ₆ O ₂ (B)b. Its chemical structural formula is as follows (III):

Emamectin benzoate is a new type of high-efficiency semi-synthetic antibiotic insecticide synthesized from the fermented product abamectin B1. features. It has extremely high activity against the larvae of Lepidoptera insects and many other pests and mites. It has both stomach poisoning and contact killing effects, and it does little harm to beneficial insects in the process of controlling pests, which is beneficial to the comprehensive control of pests.

In agricultural production, insecticide resistance is an important issue affecting pest control. Since emamectin benzoate has been used in a large area in my country for many years, it has produced different degrees of drug resistance in various places, which has affected the effect of pest control. An effective way to control resistant pests is to compound ingredients from different species.

2. Determination of biological activity

In order to further understand the toxicity of the combination of ZJ4042 and emamectin benzoate or avermectin to pests, a large number of formula screening tests were carried out. The test refers to the Indoor Bioassay Test Guidelines for Insecticides and Pesticides (Agricultural Industry Standard NY/T1154.7-2006) and the SOP for the Evaluation of Bioactivity of Pesticides (Insecticide Volume), using the dipping method.

The combined effect is calculated using the following method:

Theoretical mixed toxicity index (TTI) = Toxicity index of A × A content in mixed use (%)

    Toxicity index of +B × B content in the mixture (%)

If the co-toxicity coefficient is greater than 120, it indicates a synergistic effect; if it is less than 80, it indicates an antagonistic effect; if it is greater than 80 but less than 120, it indicates an additive effect.

The results show that: ZJ4042 emamectin benzoate or abamectin mixture has very high insecticidal activity on the tested targets, ZJ4042 and emamectin benzoate or avermectin All of these compounds showed significant synergistic effects after being mixed, and the activity of the mixture was significantly higher than that of the control single agent.
