Embodiment 1

[0065] Example 1: 26.5% nicosulfuron · oxazone · fluroxypyr isooctyl water dispersible granules

[0066] Nicosulfuron 1.5%, fenflurzone 15%, fluroxypyr isooctyl 10%, sodium lauryl sulfate 5%, p-methoxy fatty amidobenzenesulfonic acid 8%, ammonium sulfate 2 %, kaolin makes up 100%; mix the above-mentioned active ingredients, dispersant, wetting agent, disintegrating agent and solid carrier evenly, pulverize with an ultra-fine jet mill, knead, and then add it to a fluidized bed granulation dryer to make 26.5% nicosulfuron · oxazone · fluroxypyr isooctyl water dispersible granules can be prepared.

Embodiment 2

[0067] Example 2: 29% nicosulfuron · oxazone · fluroxypyr isooctyl wettable powder

[0068] Nicosulfuron 1.5%, fenflurzone 7.5%, fluroxypyr isooctyl 20%, sodium butyl naphthalene sulfonate 6%, fatty acid ester sulfate 8%, and diatomaceous earth make up 100%; The active ingredient, dispersant, wetting agent and solid carrier are mixed above, mechanically pulverized and then pulverized by air flow, and mixed uniformly to obtain 29% nicosulfuron-oxaflumezone-fluroxypyr-isooctyl wettable powder.

Embodiment 3

[0069] Example 3: 38% nicosulfuron · oxazone · fluroxypyr isooctyl oil suspension

[0070] Nicosulfuron 3%, fenflurzone 15%, fluroxypyr isooctyl 20%, polycarboxylate 10%, sodium dodecylbenzene sulfonate 10%, sodium alginate 1.5%, oil Nicotinic acid methyl ester makes up 100%; after the above active ingredients and additives are dispersed by high-speed shearing and sand-milled in a sand mill, a highly dispersed and stable suspension system formed in a non-aqueous medium can be obtained. Long 3%, fenflurzone 15%, fluroxypyr isooctyl 20% oil suspension concentrate.

Abstract

The invention relates to the technical field of pesticide compounding. The invention relates to the technical field of herbicides, in particular to a topramezone-containing corn field herbicide composition and application, wherein the herbicide composition comprises an active component A, an active component B and an active component C, the active component A is nicosulfuron, the active componentB is topramezone, and the active component C is fluroxypyr-mepthyl. The three active ingredients of the herbicide composition have complementary advantages and synergistic effects, are safe to corn and afterreap crops, reduce the use amount of the active ingredients, reduce adverse effects on the environment, have a wide weed control spectrum and can control various weeds in a corn field at a time.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a cornfield herbicide composition containing fenfentrazone and its application. Background technique [0002] The weed community in the corn field is mainly composed of crabgrass, barnyardgrass, quinoa, black nightshade, goosegrass and other weeds. Under the long-term action of chemical herbicides, the community structure has undergone great changes in recent years. The damage degree of weeds such as Commelina, Chickweed, and Aquinas in the spring corn area of ​​Northeast China has been increasing, and they have gradually evolved into the main weeds in the field. However, the dominance of hard-to-control weeds Amaranth and Abutilon in the field in the summer corn area of ​​North China has increased significantly, and the problems of weed resistance, population succession and phytotoxicity in chemical control of farmland weeds are becoming more and more serious.
