Embodiment 1

[0058] Example 1: 24.4% Chlorfluazuron Pyriproxyfen Suspension Concentrate (1:60)

[0059] 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

[0062] Example 2: 22% Chlorfluazuron Pyriproxyfen Water Dispersible Granules (1:43)

[0063] 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

[0066] Example 3: 15.5% chlorfluazuron · pyriproxyfen wettable powder (1:30)

[0067] 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 its application, and relates to the technical field of pesticide compounding. The pesticidal composition of the present invention comprises active ingredients A and B. The active ingredient A is chlorfluazuron, and the active ingredient B is any one or more of pyriproxyfen and cyromazine. The weight ratio of active ingredients A to B is 1:60-70:1. The above-mentioned compound has a reasonable ratio and has a significant synergistic effect, especially on Diptera pests such as tardy-eyed fungus, Liriomyza sativae and its nymphs, etc., which can effectively reduce the application amount of each single agent, To achieve the purpose of delaying drug resistance and reducing costs, it has obvious application and promotion 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...
