Abstract

The invention relates to an agricultural insecticidal composition, in particular to an insecticidal sterilizing composition containing lufenuron and difenoconazole, which is characterized in that organic silicon is used as a synergistic agent to be added into the insecticidal sterilizing composition. The cream of the lufenuron and difenoconazole comprises following raw materials by weight percent: 5 percent of lufenuron, 10 percent of difenoconazole, 3 percent of organic silicon, 8 percent of fatty alcohol-polyoxyethylene ether, 6 percent of agricultural emulsifier No.500 and balance of solvent naphtha, and the raw materials are placed into a mixing kettle to be mixed to produce the cream with 5 percent of lufenuron and 10 percent of difenoconazole according to a conventional method for preparing cream; and the organic silicon refers to an organic silicon surface active agent containing trisiloxanes or a modified trisiloxanes structure. The insecticidal sterilizing composition of the lufenuron and difenoconazole belongs to a novel farm chemical with low toxicity, high efficiency and low residue. By compounding the lufenuron and the difenoconazole, an action on improving the toxicity of crops and controlling both diseases and insect pests can be realized. Not only can the control range be enlarged, but also the application times of the farm chemical can be reduced, and the labor efficiency can be improved.

Description

[0001] This patent application is a branch of an invention patent application (application number: 200810163724.2, filing date: 2008-12-31, invention and creation name: insecticidal and fungicidal composition containing lufenuron, difenoconazole and silicone synergist). case application. technical field [0002] The invention relates to an agricultural insecticidal composition, in particular to an insecticidal and fungicidal composition composed of lufenuron and difenoconazole, and organic silicon is added as a synergist. Background technique [0003] At present, human beings attach great importance to environmental problems, and then put forward higher requirements for the toxicity of pesticides and their impact on the environment. Highly toxic organophosphorus pesticides are gradually eliminated due to toxicity and environmental problems. In recent decades, many new high-efficiency and low-toxic agents have been researched and developed to replace highly toxic organophosph...
