Embodiment 1

[0017] Weigh 5g of clothianidin, 60g of tetraprole, 3g of allicin, 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 · Ibuprole water dispersible granules.

Embodiment 2

[0019] Weigh 60g clothianidin, 5g tetraprole, 5g NNO, 1g sodium lauryl sulfate, 3g allicin, 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. Form the wettable powder of tetraprole and clothianidin whose main active ingredient is 65% by weight.

Embodiment 3

[0021] Weigh 30g of clothianidin, 35g of tetraprole, 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, mix at high speed, then add to the sand mill, sand mill for 2 hours, and the D90 is less than 5 microns. A clothianidin·bufenapyr suspension concentrate with a main active ingredient weight percentage of 65% was formed.

Abstract

The invention relates to an insecticidal composition for efficiently preventing and controlling Chinese chive maggots. The insecticidal composition is prepared from clothianidin, flufiprole and an attractant in a mass ratio of 1 to (0.0125 to 80) to (0.0125 to 1), wherein the attractant is prepared from sulfides having special odors such as allicin, quercetin and a Chinese chive element, or sulfides having smell similar to allium liliaceous vegetables. The insecticidal composition can penetrate into vegetable bodies; the attractant is provided, so that the insecticidal composition has an efficient pest killing effect on the Chinese chive maggots as soil pests in a seedling stage of the allium liliaceous vegetables.

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 ...
