Problems solved by technology

The combination of the two can only be made into low-content emulsifiable concentrates, microemulsions and solid preparations, and the general content is no more than 20%; its disadvantages are: 1) wherein the solvent is an organic solvent, which has a large pollution to the environment; 2) The content of active ingredients is low (generally 5-15% when used), which causes serious waste of packaging and brings a lot of inconvenience to production, storage and transportation

Abstract

The invention discloses a pyriproxyfen and acetamiprid containing a dispersible oil suspension and a preparation method thereof. The oil suspension comprises the following components in percent by weight: 4-20% of pyriproxyfen, 5-30% of acetamiprid, 5-25% of an emulsifier, 1-5% of a dispersant, 1-10% of a penetrant, 1-5% of a stabilizer, 1-5% of a thickener and the balance of a dispersing medium.The oil suspension is strong in osmotic conductivity, good in adhesion, resistant to rain erosion, better in pesticidal effect exertion, high in utilization rate of effective components and environment-friendly in dosage form, is mainly applied to control of pests, such as aleyrodids, planthoppers, aphids, thrips and coccids, on vegetables, cotton, rice, wheat and fruit trees.

Description

technical field [0001] The invention belongs to the field of compound pesticides, in particular to a dispersible oil suspension containing pyriproxyfen and acetamiprid and a preparation method thereof. Background technique [0002] Pyriproxyfen, also known as Mieyoubao, Pyroxyfen, chemical name: 4-phenoxyphenyl-(RS)-[2-(2-pyridyloxy)propyl]ether, is a A new type of phenyl ether insect growth regulator was successfully developed by Japan's Sumitomo Chemical Industry Co., Ltd. It has the characteristics of high efficiency, less dosage, long duration, safety to crops, low toxicity to fish, and little impact on the ecological environment. It can be used to control pests of Homoptera, Thysanoptera, Diptera and Lepidoptera. Its inhibitory effect on insects is affecting the molt and reproduction of insects. For the sanitary pests of mosquitoes and flies, the use of low doses of this product in the late 4th instar larvae will lead to the death of the pupation stage and inhibit th...
