Problems solved by technology

[0005] At present, chemical control is still the main method for the control of agricultural pest mites. The long-term use of single-dose products has gradually increased the resistance of pest mites to the active ingredients, and the speed of resistance development has accelerated. The main way to deal with this phenomenon is to develop and integrate with existing New active ingredients with no cross-resistance or reasonable compounding of existing pesticide varieties. Due to the high cost and long cycle of the former method, reasonable compounding of existing pesticide varieties is the best choice

[0024] Experimental Example 2 Indoor Toxicity Determination to Apple Panonychus

[0025] The original drugs of doramectin, pymetrozine and etoxazole were compounded according to the weight ratios shown in Examples 1-6, respectively, and diluted to gradient concentrations of 20ppm, 40ppm, 80ppm, 160ppm, 320ppm, and treated with clean water As a control, the tested insect was Panonychus apple, the bioassay method was the leaf soaking method, the number of dead insects were investigated at 36 hours, and the co-toxicity coefficient of the mixture was calculated by Sun Yunpei's method. The test results are shown in Table 1, CTC≥120 It means synergistic effect, 80<CTC< means additive effect, CTC≤80 means antagonistic effect, and the measurement results are shown in Table 3.

Abstract

The invention discloses an acaricidal composition. Effective components of the acaricidal composition comprise doramectin, pymetrozine and etoxazole. The acaricide has the advantages that the prevention and treatment effect is superior to single component, the consumption of the acaricide is reduced, the cost is low, and the production of pest resistance is delayed; the acaricidal composition has good effects of preventing and treating common agricultural mites such as tetranychus cinnabarinus and panonychus ulmi and the like and has a good application prospect of being developed into a new pesticide mixture.

Description

Technical field [0001] The invention belongs to the field of pesticide acaricides, and specifically relates to an acaricide composition using doramectin, pymetrozine and etoxazole as active ingredients and its use in preventing and controlling agricultural pest mites. Background technique [0002] Doramectin, a third-generation derivative of the new macrolide antibiotic abamectin, is obtained by fermentation of a new strain of Streptomyces arermitilis that is genetically recombined. It is a new type of Broad-spectrum insecticide, especially for mites, has a good control effect. [0003] Pymetrozine (pymetrozine) is a pyridine or triazinone insecticide developed by Novartis of Switzerland in 1988. Its insecticidal mechanism is to act on the amine [5-hydroxytryptamine (vasoconstrictor) in the blood of the insect ) Serotonin] signal transmission pathway, which leads to a response similar to neurotoxicity. The nerve center of pest feeding behavior is inhibited. It interferes with nor...
