Embodiment 1

[0042]Weigh 15% bromofluben, 30% chlorfenapyr, 8% alkylphenol polyoxyethylene ether, 6% pull-off powder BX, 5% ammonium sulfate, 3% sodium carboxymethyl cellulose, white carbon Black makes up the margin. Mix the above raw materials evenly, pulverize and mix evenly with an ultra-fine airflow mill, add water to knead and granulate, dry and sieve in a boiling dryer, and after testing and analysis, you can make 35% bromflubfluben. Chlorfenapyr water dispersible granules.

Embodiment 3

[0044] Weigh 10% chlorfenapyr, 5% chlorfenapyr, 10% sodium lignosulfonate, 5% sodium dodecylbenzenesulfonate, 1.5% ethylene glycol, 0.6% xanthan gum, 0.4% Hexanol, 3% trisiloxane, 0.8% sodium benzoate, and deionized water make up the balance. Mix deionized water and other additives evenly through a high-speed shearing homogenizer, then add the active ingredients bromflubendi and chlorfenapyr, and perform sand grinding in a sand mill to make the particle size D90 of the suspension agent at 5 μm The following can be made into 15% bromflubendichlorfenapyr suspension concentrate.

[0045] 4. Embodiment 4

Abstract

The invention relates to the technical field of pesticide compounding, in particular to an insect-killing composition containing broflanilide and chlorfenapyr. A weight ratio of broflanilide to chlorfenapyr is from 1:50 to 50:1. The insect-killing composition has the advantages that the advantages of the two effective components can be complemented, so as to really achieve the synergistic and spectrum-expanding effects; after the two active components are mixed according to a certain ratio, the obvious synergistic effect is realized, the usage amount of each single reagent can be reduced, andthe preventing and control effect is improved; the applying amount and use frequency of broflanilide can be reduced, and the pesticide residue can be relieved.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing chlorfenapyr and chlorfenapyr. Background technique [0002] Plutella xylostella, Lepidoptera Xylostella, Plutella xylostella (Linnaeus); Another name: small caterpillar, two pointed. It is a worldwide migratory pest and mainly damages Brassicaceae plants such as cabbage, purple cabbage, broccoli, mustard greens, cauliflower, cabbage, rape, and radish. Damage characteristics: the first instar larvae only eat the mesophyll, leaving the epidermis, forming transparent spots on the vegetable leaves, "opening the skylight", the 3rd to 4th instar leaves eat holes and nicks, and in severe cases, the whole leaf is eaten into a net . In the seedling stage, the center leaves are often damaged, affecting the heart of the package. On seed-retaining plants, the young stems, young pods and grains are harmed. [0003] Cutworms belong to t...
