[0046] Synergistic test of 6% lufenuron·abamectin microemulsion

[0047] This test adopts the leaf soaking method, and sets the concentration gradient of each pesticide series according to the results of the preliminary test. Each treatment is about 30 beet armyworm larvae, and it is repeated three times. Soak fresh and pollution-free cabbage leaves in a certain concentration of medicinal solution for a few seconds, and after drying, connect healthy and uniform 2-3 instar larvae of beet armyworm, put them in a glass dish, and raise them under the same conditions. After 48 hours Check the death of the test insects. Judgment of mortality, toxicity regression equation and its LC50. As a result of the test, its CTC value was greater than or equal to 120, indicating that it had a synergistic effect (see Table 2).

Abstract

The invention relates to a pesticide composite, which has a component A and a component B, wherein the component A is lufenuron and the component B is one of abamectin and emamectin-benzoate. A formulation screening test result shows that a microemulsion, an aqueous agent, a suspending agent or a water dispersible granule is prepared by combining the lufenuron and the abamectin, or the lufenuron and the emamectin-benzoate according to a certain proportion and the preparation obtained has obvious synergic effect and lasting effect after the combination; furthermore, the pesticide composite acquires multiple functions on diamond back moths, asparagus caterpillars and other pests of vegetables, fruit trees and cotton, such as wide spectrum, high efficiency, low toxicity, low pollution and low residual, remarkably reduces the using amount and using frequencies of the medicines, reduces cost and defers the drug resistance of the pests.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a pesticide composition. Background technique [0002] Lufenuron (English name Lufenuron), chemical name: N-[[[2,5-dichloro-4-(1,1,2,3,3,3-hexafluoropropoxy)phenyl]amino]carboxyl ]-2,6-Difluorobenzamide is a benzoylurea acaricide and insecticide, an insect growth regulator, and a chitin synthesis inhibitor. It is mainly used to control beet armyworm, Spodoptera litura, cabbage armyworm, diamondback moth, cotton bollworm, rust mite, citrus leafminer, planthopper, etc. Has stomach poisoning and contact killing effects, unique insecticidal mechanism: inhibits insect peeling, insecticidal and egg killing effects, pests stop eating crops sprayed with lufenuron for 2 hours, and enter the peak of dead insects in 2-3 days . Its characteristics are ① low toxicity, suitable for the production of pollution-free agricultural products. ② Kill insects and kill eggs, kill large and small larvae, a...
