Embodiment 1

[0057] Example 1: 24.4% Chlorfluazuron Pyriproxyfen Suspension Concentrate (1:60)

[0058] Chlorfluazuron 0.4%, pyriproxyfen 24%, Nongru 400 # 5%, sodium lauryl sulfate 2%, sodium lignosulfonate 5%, silicone oil 1%, polyethylene glycol 2%, sodium carboxymethylcellulose 5%, deionized water to make up 100%. The above raw materials were mixed according to the conventional method for preparing a suspending agent to prepare a 24.4% chlorfluazuron · pyriproxyfen suspending agent.

Embodiment 2

[0061] Example 2: 22% Chlorfluazuron Pyriproxyfen Water Dispersible Granules (1:43)

[0062] Chlorfluazuron 0.5%, pyriproxyfen 21.5%, wetting and penetrating agent (F) 5%, sodium lignosulfonate 4%, bentonite 2%, kaolin supplement 100%. The above raw materials were mixed according to the conventional method for preparing water-dispersible granules to prepare 22% chlorfluazuron·pyridroxyfen water-dispersible granules.

Embodiment 3

[0065] Example 3: 15.5% chlorfluazuron · pyriproxyfen wettable powder (1:30)

[0066] Chlorfluazuron 0.5%, pyriproxyfen 15%, sodium lauryl sulfate 10%, sodium lignosulfonate 8%, kaolin supplement 100%. The above raw materials were mixed according to the conventional method for preparing wettable powder to prepare 15.5% chlorfluazuron · pyriproxyfen wettable powder.

Abstract

The invention discloses an insecticidal composition and application thereof and relates to the technical field of pesticide compounding. The insecticidal composition disclosed by the invention contains an effective ingredient A and an effective ingredient B. The effective ingredient A is chlorfluazuron, and the effective ingredient B is one or both of pyriproxyfen and cyromazine. The weight ratio of the effective ingredient A to the effective ingredient B is (1: 60) to (70: 1). The compounded agent is reasonable in proportioning ratio, has a remarkable synergistic effect and particularly has an excellent effect on Diptera pests such as Bradysia odoriphaga, Liriomyza sativae and nymphs thereof, and the like, the amount of application of each single agent can be effectively reduced, and the aims of retarding drug resistance and reducing cost are achieved, so that the compounded agent has an obvious application and popularization value.

Description

technical field [0001] The present invention relates to an insecticidal composition and its application, in particular to an insecticidal composition with any one of chlorfluazuron, pyriproxyfen, and cyromazine as active ingredients and its application, which belongs to the pesticide compounding technology field. Background technique [0002] In the actual process of agricultural production, chemical control is still the most effective means of controlling pests, but due to the continuous and large-scale use of chemical insecticides, the problem of pest resistance has become increasingly prominent. Moreover, the pests that are prone to resistance to pesticides are usually those with large reproduction numbers and obvious overlapping generations. Such as planthoppers, aphids, spider mites, diamondback moths, etc. [0003] The tardy-eyed fungus belongs to the order Diptera and belongs to the family Mycidae. It mainly harms leeks, green onions, onions, shallots, garlic and o...
