Problems solved by technology

[0005] Although spirodiclofen has many unique advantages, there are still some defects in the process of use: spirodiclofen is slow in killing mites and has poor quick effect, so it should not be used when a large number of agricultural pest mites break out, especially not suitable for use alone use
However, the N-multi-substituted-1,2,3-thiadiazole-5-carboxamidine compound whose general formula is TDCA is not strong enough to the toxicity of some adults, and it needs to be acaricide (such as Avi) with high adult killing activity. Bacterin, spirodiclofen, etc.) for mutual use

Abstract

The invention discloses a synergistic acaricidal composition which comprises acceptable auxiliary components in pesticides and N-(5-tertiary butyl-1,3,4-thiadiazole-2-base)-N'-(2,6-substituted dihydropyridine-4-base)-N,4-dimethyl-1,2,3-thiadiazole-5-formamidine (TDCA for short) and spirodiclofen serving as effective components. The weight ratio of the TDCA-6 to the spirodiclofen ranges from 40:1 to 1:40. Indoor experiments and field effect experiments indicate that antagonism is avoided after the two effective components are combined, and the composition has remarkable synergistic effects and safe to crops.

Description

technical field [0001] The present invention relates to an insecticidal and acaricidal composition, in particular to an insecticidal and acaricidal composition containing spirodiclofen and N-trisubstituted-1,2,3-thiadiazole-5-carboxamidine compounds The composition belongs to the field of pesticide preparations. Background technique [0002] Acarid belongs to Arthropoda, Arachnida, Acarina, and individual is smaller. All stages of mites may be present in a colony, including eggs, nymphs, larvae and adults. Most of them live in dense clusters on the back of leaves of fruit trees, vegetables, cotton, peanuts and other crops and ornamental plants, and their rapid reproduction and high degree of selfing all determine that mites are difficult to control. On the other hand, farmers are accustomed to continuously using a single acaricide with good acaricidal effect, which results in the acaricide developing resistance for a long time and losing its use value. Therefore, the use ...
