Problems solved by technology

[0002] At present, imidacloprid is the first choice for controlling rice planthoppers. Imidacloprid pesticide preparations include wettable powder, emulsifiable concentrate, water, water dispersible granules and effervescent tablets. It cannot be sprayed. Like wettable powder, emulsifiable concentrate, and water, it can only be used for spraying, but the effect of spraying on rice planthoppers that inhabits at the base of rice stems is poor; effervescent tablets, because of their large size, can be

Embodiment Construction

[0009] specific implementation plan

[0010] In an embodiment, a granule made of imidacloprid is composed of 2 g of imidacloprid, 1000 g of sand grains and polyvinyl alcohol. The preparation method is as follows: using screened sand grains or similar materials as a carrier, adding an appropriate amount of imidacloprid liquid medicine and dichlorvos liquid medicine to adsorb on strong adsorbent, and then use polyvinyl alcohol as a coating agent to wrap the outer layer of sand or similar materials and dry them.

[0011] Application method of imidacloprid granules: due to the low toxicity of the agent, it can be spread directly by hand without any equipment. It is usually applied from the booting stage to the milk ripening stage of rice, and the application rate is about every 667m 2 Spray imidacloprid granules 2~3kg; frequency of application: 30 days after each application, depending on the occurrence of rice planthoppers, apply the second application as appropriate.

Abstract

A granular imidacloprid with high effect and solubility is prepared from imidacloprid, dichlorvos, carrier (sand) and strong adsorbent through adsorbing imidacloprid and dichlorvos by strong adsorbent, coating by PVC or paraffin wax, and baking.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to a granule made of imidacloprid and a preparation method thereof. Background technique [0002] At present, imidacloprid is the first choice for controlling rice planthoppers. Imidacloprid pesticide preparations include wettable powder, emulsifiable concentrate, water, water dispersible granules and effervescent tablets. It cannot be sprayed. Like wettable powder, emulsifiable concentrate, and water, it can only be used for spraying, but the effect of spraying on rice planthoppers that inhabits at the base of rice stems is poor; effervescent tablets, because of their large size, can be used Throwing, but because the field coverage is small and the distribution is uneven, the control effect is not good, especially in the case of insufficient water level in the paddy field, the drug cannot be dissolved and diffused, which affects the control effect. The app...
