Detailed Description
The invention provides a synergistic composition mainly comprising dicyclopropyl tetramisole and pyridalyl, which has obvious synergistic effect on preventing and treating pests with piercing-sucking mouthparts or rasping-sucking mouthparts.
Compared with a single agent, the composition has obvious synergy on the piercing-sucking pests, and improves the application effect; the field dosage is greatly reduced, the use cost is reduced, and the environmental pollution and the pesticide residue are reduced; the two active ingredients in the composition have completely different action mechanisms, so that the generation of drug resistance of pests is overcome, and the treatment of resistant pests is facilitated.
Compounding the pesticide active ingredients with different structure types is an effective measure for solving the problems of cost, resistance and the like in the use process of a single pesticide. Pesticide active ingredients of different structural types generally exhibit three types of action, namely additive action, synergistic action and antagonistic action, when mixed. However, the specific action cannot be predicted, and can only be concluded through a large number of experiments. The formula with good compound synergism can improve the actual control effect, reduce the dosage of pesticides, is beneficial to delaying the generation of resistance, and is one of important means for resistance treatment.
The compositions according to the invention have a marked synergistic effect on thrips, whitefly, etc., and not only a simple addition of the effects of the two agents, as is evident from the results of the examples below.
In the present invention, it should be noted that:
mortality (%) = dead insects/total number of treated insects 100
Corrected mortality (%) = (treatment group mortality-control group mortality)/(1-control group mortality) × 100, statistical analysis was performed using DPS9.50 statistical analysis software, LC50 of each drug was calculated by correcting mortality for each treatment with different concentration gradients, and co-toxicity coefficient (CTC) was calculated by the sun cloud lung method.
When the CTC is less than or equal to 80, the composition shows antagonism, when the CTC is more than 80 and less than 120, the composition shows additive action, and when the CTC is more than or equal to 120, the composition shows synergism.
Actually measured virulence index (ATI) = (standard medicament LC 50/test medicament LC 50) × 100
Theoretical virulence index (TTI) = a agent virulence index x percent a in the mixture + B agent virulence index x percent B in the mixture.
Co-toxicity coefficient (CTC) = [ measured toxicity index (ATI)/theoretical toxicity index of the mixture (TTI) ] × 100.
In the description of the present invention, the pesticidal composition, which is used for controlling pests on crops, may be provided in the form of a finished preparation, i.e., in the form of a mixture, or the components of the composition may be provided in the form of a single dose, mixed in proportion in a tank or a can directly before use, and then diluted to a desired concentration.
