Embodiment 3
[0055] Example 3 : 15% Thiacloprid Spirofen Emulsion in Water
[0056]
[0057] The preparation method of the water-emulsion described in the above-mentioned embodiment 1-3 is: after fully dissolving the active ingredients thiacloprid and spirodiclofen with a solvent and a cosolvent, drop into an emulsifier, a dispersant, a wetting agent and fully stir to form an oil phase; add antifreeze to water to dissolve to form a water phase; slowly add the water phase to the oil phase, and use a high-speed shear to shear to obtain a water emulsion.

The invention belongs to the technical field of pesticide application and particularly relates to acaricidal composition containing thiacloprid and spirodiclofen. The acaricidal composition is prepared by compounding thiacloprid and spirodiclofen as effective components at a mass ratio ranging from 1:50 to (50:1). The composition has remarkable prevention and control effects on panonychus citri, panonychus ulmi and tetranychus cinnabarinus. The composition has the advantages of capabilities of remarkably improving an effect, reducing pesticide consumption, reducing prevention and control costs, delaying resistance and alleviating environmental pollution.
Description
technical field [0001] The invention belongs to the technical field of pesticide application and relates to a pesticide composition, in particular to an acaricidal composition containing thiacloprid and spirodiclofen. Background technique [0002] Thiacloprid is a new type of chloronicotinoid insecticide, which was jointly developed by Bayer Agrochemical Company of Germany and Bayer Agrochemical Company of Japan in the 1990s. It has special effects on piercing-sucking and chewing mouthparts pests. The mechanism of action is different from other traditional insecticides. It mainly acts on the post-junction membrane of insect nerves. By binding to nicotinic acetylcholine receptors, it interferes with the normal conduction of the insect nervous system, causing blockage of nerve channels, resulting in a large accumulation of acetylcholine. As a result, the insect is extremely excited, and the whole body convulses, paralyzes and dies. It has strong contact, stomach poisoning an...
