Embodiment 1

[0018] Weigh 5g of clothianidin, 60g of flubenzuron, 5g of sodium naphthalenesulfonate formaldehyde condensate, 3g of powder, and 100g of cornstarch. Put the above raw materials into the mixing kettle and mix them at high speed, then add them to the mixer, add 15% water and mix them into a wet material, extrude, granulate, sand mill, and dry in a fluidized bed to form a main active ingredient with a weight percentage of 65% % Clothianidin·flubenzuron water dispersible granules.

Embodiment 2

[0020] Weigh 60g clothianidin, 5g flubenzuron, 5g NNO, 1g sodium lauryl sulfate, and kaolin to 100g. Put the above raw materials into the pre-mixing tank according to the conventional preparation method and mix them, then carry out jet milling, and the particle size D90 is less than 15 microns. A flubendron·clothianidin wettable powder with a main active ingredient weight percentage of 65% is formed.

Embodiment 3

[0022] Weigh 30g of clothianidin, 35g of flubenzuron, 2g of phenylethylphenol polyoxyethylene ether phosphate, 5g of agricultural milk 33#, 3g of emulsifier 600#, 5g of vegetable oil, and add water to 100g. Put the above raw materials into the mixing tank according to the conventional method of preparing water emulsion and mix them at high speed, then add them to the sand mill, and sand them for 2 hours, D 90 less than 5 microns. Clothianidin·flubenzuron suspension concentrate with a main active ingredient weight percentage of 65% is formed.

Abstract

The invention relates to a clothianidin-containing pesticidal composition for controlling bradysia odoriphaga. The clothianidin-containing pesticidal composition comprises clothianidin and flufenoxuron, wherein the mass ratio of the clothianidin to the flufenoxuron is 1:80 to 80:1, and the active components account for 1-80% of the total content of a preparation. The clothianidin-containing pesticidal composition can be prepared into the conventional pesticidal dosage forms including missible oil, an aqueous emulsion, a microemulsion, a suspending agent, wettable powder, water-dispersible granules or the like. The clothianidin-containing pesticidal composition can have a high-efficiency pesticidal effect on underground pests bradysia odoriphaga in the seedling stages of liliaceous vegetables such as onion and garlic.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an insecticidal composition for efficiently controlling chive maggots. Background technique [0002] Chive maggots belong to the order Diptera and belong to the family Oculomidae. It mainly harms leeks, scallions, onions, shallots, garlic and other lily vegetables, and has obvious tendency to the smell emitted by onion and garlic vegetables. In the past, in the process of using chemical pesticides to control leek maggots, the use of highly organophosphorus pesticides for root irrigation is the most effective method. Since the limited use of organophosphorus pesticides, the most common is the use of pyrethroid poisoning pesticides Spray control was carried out, but the effect was poor. [0003] Leek maggot is one of the main pests of onion and garlic vegetables in northern my country. However, there is no low-toxicity chemical pesticide preparation for effective control of leek maggot ...
