Abstract

The invention relates to a composition for controlling cnaphalocrocis medinalis, and the composition has contact killing property, stomach toxicity and ovicidal action, and comprises the following two active ingredients: abamectin and pyriproxyfen, wherein the weight ration of the abamectin to the pyriproxyfen is (1: 3) to (1: 14). Effective dose of the abamectin and the pyriproxyfen, a solid or liquid carrier, auxiliaries and other additives are used, the composition preparation is prepared by the conventional method, the composition preparation is used for treating the cnaphalocrocis medinalis or a habitat thereof, and the weight ratio of the abamectin to the pyriproxyfen in the composition preparation is (1: 3) to (1: 14). The composition can be used for overcoming the defect of short lasting period in the prior art, and shows significant synergy; and the application of the smaller dose of the composition for processing the cnaphalocrocis medinalis can show excellent contact killing property, stomach toxicity and ovicidal effect. The lasting period of the composition is long, and the quick killing activity for the cnaphalocrocis medinalis can be simultaneously enhanced.

Description

technical field [0001] The present invention relates to a composition for controlling rice leaf roller, in particular to a composition for preventing and treating rice leaf roller with contact killing, stomach toxicity and ovicidal effect and its preparation. The composition contains a Two active components, vermectin and pyriproxyfen, belong to the technical field of pesticides. Background technique [0002] The rice leaf roller is the most important migratory pest that harms rice, and a small amount of it overwinters in areas south of 30°N latitude in China. The occurrence algebra in different places in one year is quite different due to the difference in the time of immigration. For example, 2-3 generations in northern Hebei and Shandong; 4-5 generations in Xinyang, Henan, the middle and lower reaches of the Yangtze River such as Hubei, Anhui, Jiangsu, Shanghai and northern Zhejiang; Guangxi has 6-7 generations; Lingshui County in Hainan Province has 10-11 generations. ...
