Embodiment 1

[0018] Embodiment 1: prepare the oil suspension concentrate (methylsulfuron-methyl: bensulfuron-methyl=1: 4) of compound herbicide of the present invention

[0019] 4% Mesulfuron-methyl-bensulfuron-methyl oil suspension concentrate, 4% refers to the percentage of the two active components of Mesulfuron-methyl and Bensulfuron-methyl in the total weight. Take 0.8kg methylsulfuron-methyl, 3.2kg bensulfuron-methyl, 8kg Pluronic125, 5kg propylene glycol, 0.5kg xanthan gum, and methylated vegetable oil to make up to 100kg. The oil suspension is obtained through full mixing and preparation, ball milling, adjustment and packaging.

Embodiment 2

[0020] Embodiment 2: prepare the wettable powder of compound herbicide of the present invention (methylsulfuron-methyl: bensulfuron-methyl=1:5)

[0021] 30% Mesulfuron-methyl-bensulfuron-methyl wettable powder, 30% refers to the percentage of the two active components of Mesulfuron-methyl and Bensulfuron-methyl in the total weight. Take 5kg methylsulfuron-methyl, 25kg bensulfuron-methyl, 4kg dispersant NNO, 3kg wetting agent K12, 4kg white carbon black, and light calcium carbonate to make up to 100kg. Wettable powder is obtained through thorough mixing, jet milling and mixing.

Embodiment 3

[0022] Embodiment 3: prepare the water dispersible granule of compound herbicide of the present invention (methylsulfuron-methyl: bensulfuron-methyl=1:6)

[0023] 70% mesosulfuron-bensulfuron-methyl water-dispersible granule, 70% refers to the percentage of the two active components mesosulfuron-methyl and bensulfuron-methyl to the total weight. Take 10kg of methylsulfuron-methyl, 60kg of bensulfuron-methyl, 7kg of D-425, 5kg of EFW, 5kg of ammonium sulfate, 2kg of polyethylene glycol, and kaolin to make up 100%. After fully mixing, jet milling, mixing, granulation, and drying and sieve to obtain water-dispersible granules.

Abstract

The invention relates to the technical field of agricultural chemicals and discloses a wheat post-emergence compound herbicide. The wheat post-emergence compound herbicide comprises two active ingredients including mesosulfuron-methyl and bensulfuron-methyl; the weight ratio of mesosulfuron-methyl and bensulfuron-methyl 1:4-10; preferably, the mass percent of mesosulfuron-methyl and bensulfuron-methyl in the compound herbicide is 3% to 85%. The post-emergence compound herbicide provided by the invention can prevent and eliminate not only annual grass family weeds but also broadleaf weeds, and the weeding effect is remarkable; besides, the post-emergence compound herbicide has remarkable synergism, has no influence on succeeding crops and is an ideal herbicide.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a post-emergence compound herbicide for wheat. Background technique [0002] Wheat is one of the main food crops in northern my country, and it is also an important feed crop. The annual planting area in my country is more than 30 million hectares, second only to the rice planting area. The area of ​​wheat field weed damage accounts for more than 30% of the total planting area, of which more than 8% are severely damaged, and the yield is generally reduced by more than 15%, and in severe cases, the harvest may be completely eliminated. Therefore, the proportion of herbicides used in domestic wheat fields is almost 100%, and the dosage is very large. At present, the main herbicides for post-emergence control of weeds in domestic wheat fields are: pyroxaprop-ethyl, methylsulfuron-methyl, flucarbasulfuron-methyl, tribenuron-methyl, fluroxypyr, dicamba, metsulfuron-methyl , thias...
