Problems solved by technology

However, due to the long-lasting effect of atrazine, it is harmful to sensitive crops such as wheat, soybeans, and rice, etc., and the long-lasting effect lasts for 2-3 months.
[0005] The combination of fenfentrazone and atrazine, if the amount of atrazine is too large, there will be residual phytotoxicity on the next crop

Embodiment 1

[0020] Example 1: 31.5% oxaflumezone·sulfentrazone·atrazine dispersible oil suspension concentrate (oxentrazone: sulfentrazone: atrazine=1.5:15:15)

[0021] Take 1.5kg fentrazone, 15kg sulfentrazone, 15kg atrazine, 8kg dispersant—block polyether nonionic surfactant (Pluronic125), 5kg wetting agent—propylene glycol, 0.5kg disintegrant—yellow Raw gum, 1kg binder-methyl esterified vegetable oil, 54kg of carrier water. The dispersible oil suspension is obtained through full mixing and preparation, ball milling, adjustment and packaging.

Embodiment 2

[0022] Example 2: 42% fenflumezone·sulfentrazone·atrazine suspension concentrate (oxentrazone: sulfentrazone: atrazine=2:15:25)

[0023] Take 2kg fenfentrazone, 15kg sulfentrazone, 25kg atrazine, 8kg sodium lignosulfonate (dispersant), 5kg fatty alcohol polyoxyethylene ether (wetting agent), 1kg xanthan gum (thickener) , 2kg polyoxyethylene polyoxypropanol amine ether (defoamer), 5kg ethylene glycol (antifreeze), carrier water 37kg. The suspending agent is obtained through full mixing and preparation, ball milling, adjustment and packaging.

Embodiment 3

[0024] Example 3: 63% oxentrazone·sulfentrazone·atrazine water dispersible granules (oxentrazone: sulfentrazone: atrazine=3:20:30)

[0025] Take 3kg fentrazone, 20kg sulfentrazone, 40kg atrazine, 7kg dispersant-naphthalenesulfonate formaldehyde condensate (D-425), 5kg wetting agent-alkylnaphthalenesulfonate and anion wetting The mixture (EFW) of agent, 5kg disintegrant-ammonium sulfate, 2kg binder-polyvinyl alcohol (PVA), carrier kaolin 19kg. Water-dispersible granules are obtained through thorough mixing, jet milling, mixing, granulation, drying and sieving.

Abstract

The invention relates to post-emergence herbicide composition containing topramezone, sulfentrazone and atrazine and used for corn. Active ingredients of the herbicide composition comprise topramezone, sulfentrazone and atrazine in the weight ratio being (0.1-70): (0.1-70): (0.1-80). The herbicide composition can control annual gramineous weeds in a corn field, can control broadleaf weeds and nutgrass flatsedge and has a remarkable weed control effect and a prominent synergism effect; besides, the herbicide composition can control weeds in the whole growth period of crops after one-time application, has no influence on succeeding crops and is ideal herbicide.

Description

technical field [0001] The invention relates to the technical field of pesticide herbicides, in particular to a corn post-emergence herbicide composition containing fentrazone, sulfentrazone and atrazine. technical background [0002] Corn is not only an important food crop in my country, but also an important feed crop. In recent years, with the development of industries such as animal husbandry, food processing, wine making and biodiesel, the market demand for corn has continued to increase. In 2012, my country's corn planting area reached 39.949 million hectares, second only to rice, becoming the second largest planting crop, and there is still an increasing trend. Weeds in corn fields are common and of various types. In Huanghuaihai summer corn weeds are serious, and the area of ​​weeds accounts for 82% to 96% of the planting area in this area, and the area of ​​moderate damage is 64 to 66%. Maize seedlings are most seriously damaged by weeds, and weeds have little eff...
