Embodiment 1

[0022] Example 1: Toxicity determination of metaflumizone, spinosad and different ratios to beet armyworm

[0023] The beet armyworm collected from Yulu Village, Bao'an, Shenzhen, Guangdong, was reared indoors for three generations, and the third instar larvae with uniform growth were selected as the test insects for this experiment. The test method refers to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and "People's Republic of China Agricultural Industry Standard NY / T1154.14-2006". Using the method of soaking leaves and inoculating insects, the test agent was mixed with acetone and 10% Tuwen-80 to make a certain concentration of mother liquor, and then diluted with clear water to 5 gradient concentrations for use, and clear water was used as a control. Take fresh cabbage leaves and cut them into fragments with a length of about 40 mm and a width of about 20 mm, which are basically the same size. Immerse the cut leaves in the prepared drug solut...

Abstract

The invention relates to a pesticide composition which consists of metaflumizone and spinosyns. The composition has the advantage of synergy and can reduce the pesticide dosage, reduce pollutions to the environment and delay the development of pest resistance. The pesticide composition is applied to prevent and cure pests on crops such as vegetables, fruit trees, cotton, and the like.

Description

technical field [0001] The invention relates to a pesticide composition, specifically a pesticide composition containing metaflumizone, which is used for preventing and controlling pests on vegetables, fruit trees, cotton and other crops. Background technique [0002] Metaflumizone belongs to the group of semicarbazone insecticides. The mechanism of insecticidal action is unique, acting on the sodium ion channel on the axon membrane of pest neurons. Metaflumizone is mainly used to control Lepidoptera pests and some Coleoptera pests. Metaflumizone has good crop safety, is relatively safe to beneficial organisms including pollinators and arthropod insects, and is suitable for integrated pest management and pest resistance management. [0003] Spinosad is a microbial metabolite, a macrolide compound, and a low-toxicity, high-efficiency, broad-spectrum insecticide. The mechanism of insecticidal action is to act on insect acetylcholine nicotinic receptors, and can also affect ...
