A kind of insecticidal composition containing malathion and pyriproxyfen and its application

Abstract

The invention belongs to the technical field of agricultural pest control and particularly relates to insecticidal composition containing malathion and pyriproxyfen and an application of the insecticidal composition. Effective active components of the insecticidal composition are malathion and pyriproxyfen in a mass ratio being (1-24):1, and the better ratio of malathion to pyriproxyfen as the effective components is 6:1; preferably, the two effective active components including malathion and pyriproxyfen account for 20%-40% of the composition in percentage by mass. The composition is mainly applied to control for rice pests such as rice planthopper, rice thrips, rice leafhopper and the like and has the advantages as follows: compatible use of malathion and pyriproxyfen has an obvious synergistic effect, the field control effect is good, not only can production and development of drug resistance of the rice pests be overcome or delayed, but also the use quantity of field pesticides can be effectively reduced, pollution to the ecological environment of a paddy field due to chemical pesticides is reduced, production cost is reduced, and economic benefit of rice production is increased.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of agricultural diseases and insect pests, and in particular relates to an insecticidal composition containing malathion and pyriproxyfen and an application thereof. Background technique [0002] Rice is one of the three major food crops in the world and the most important food crop in my country. The rice planting area in China accounts for more than 30% of the country's food crop planting area, and my country's rice production accounts for 50% of the country's total food production. Therefore, rice is the most important food in my country. The status and role of social development are enormous. Rice thrips and rice planthoppers are the main pests in rice production in my country. When serious damage occurs, it will cause huge loss of rice yield. The rampant occurrence of rice thrips and rice planthoppers and other major pests has become one of the main reasons for restricting rice ...

Problems solved by technology

However, putting a large amount of pesticides into rice fields will inevitably kill a large number of natural enemies, thereby causing damage to the rice field ecosystem, causing further rampant pests to cause damage, and excessive reliance on chemical pesticides to control the occurrence of pests, resulting in a vicious circle of continuous destruction of the ecosystem
