Description

Technical Field

[0001] The present invention relates to the technical field of thrips control compositions, and more specifically, to a medicament composition for controlling lotus thrips and its application. Background Art

[0002] Lotus root is an important aquatic economic crop in China. However, during its planting and growth process, it is often invaded by thrips (Thrips palmi). Thrips suck the sap of lotus root leaves, petioles and new buds through their mouthparts, resulting in silver-white spots, curling and deformity on the leaves. Seriously, it affects photosynthesis and the swelling of lotus roots, and significantly reduces the yield of lotus roots. Moreover, thrips may also transmit viruses (such as Tomato spotted wilt virus TSWV), exacerbating the occurrence of lotus root diseases. Therefore, in the process of lotus root planting, the control of thrips is of great significance.

[0003] Currently, in the prior art, the control means mainly rely on chemical agents. However, long-term use of single-component agents is likely to lead to enhanced drug resistance, and some agents pose potential risks to the aquatic ecological environment. After retrieval, the Chinese patent with the publication number CN101356923A in the prior art discloses an insecticide containing pymetrozine and imidacloprid, which is used for controlling rice planthoppers, and aphids, thrips and other piercing-sucking mouthpart pests such as whiteflies, aphids and thrips on fruit trees, vegetables, wheat, tea trees, etc. This insecticide contains pymetrozine and imidacloprid, and its active ingredients are pymetrozine and imidacloprid. The weight ratio of pymetrozine to imidacloprid is 1:5 - 5:1. Although this existing patent makes up for the deficiencies of single-agent pesticides and overcomes the drug resistance of pests to a certain extent, the synergistic effect of its components is not good. After multiple applications, drug resistance is still likely to occur. Moreover, its effective period is short, it has a high dependence on temperature (the drug effect is positively correlated with temperature, the effect is stable at low temperatures, but the activity decreases at high temperatures), the cost is high, and it has a high toxicity to aquatic organisms.

[0004] Therefore, the present application aims to provide a medicament composition for controlling lotus thrips and its application to solve the above problems. Summary of the Invention
