Embodiment 1

[0015] A post-emergence compound herbicide for wheat, its dosage form is dispersible oil suspension concentrate, including the following components: 20kg trimethylbenzotrione, 2kg flucarbasulfuron-methyl, 8kg dispersant-block polyether nonionic surfactant (Pluronic125), 1kg methylated vegetable oil, carrier water 69kg. The above components are fully mixed and formulated, ball milled, adjusted and packaged to obtain a product.

Embodiment 2

[0017] A kind of post-emergence compound herbicide for wheat, its dosage form is water-dispersible granule, comprises following components: 27.6kg trimethylbenzotrione, 2.4kg flucarbasulfuron-methyl, 6kg dispersant-naphthalenesulfonate formaldehyde condensate ( D-425), 2kg wetting agent-the mixture (EFW) of alkylnaphthalene sulfonate and anionic wetting agent, 5kg disintegrant-ammonium sulfate, 1kg binder-polyethylene glycol, carrier kaolin 56kg. The above components are fully mixed, jet milled, mixed, granulated, dried and sieved to obtain the product.

Embodiment 3

Abstract

The invention discloses a post-seedling compound herbicide for wheat seedlings. The post-seedling compound herbicide comprises tralkoxydim and flucarbazone, the mass percent content of the tralkoxydim and the flucarbazone accounts for 0.1-85% of the total mass of the post-seedling compound herbicide, wherein the weight ratio of the tralkoxydim to the flucarbazone is (0.1-60) to (0.1-70). In comparison with a single medicament of the tralkoxydim and the flucarbazone, the use amount of the compound herbicide is low, the cost is low, and the prevention effect to monocotyledonous weeds and dicotyledon weeds in a field, the fresh weight prevention effect and the comprehensive fresh weight prevention effect are improved, and the security and the fast-acting property to the field crops are obvious. The weeds in the whole growth season of crops can be prevented and controlled through once pesticide application, the compound herbicide is safe to next-stubble crops, and especially has special effects to the resistance weeds such as aegilops tauschii and bromus japonicus in North China.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a post-emergence compound herbicide for wheat. Background technique [0002] Trimethylbenzotrione, chemical name is 2-[1-(ethoxyimino)propyl]-3-hydroxy-5-(2,4,6-trimethylphenyl)cyclohex-2-enone, molecular formula C 20 h 27 NO 3 , with a molecular weight of 329.43, a highly selective herbicide. It has systemic conduction function and is used for controlling various grass weeds in barley and wheat fields. After foliar application, it is quickly absorbed and transferred to the whole plant, and the weeds turn green and then die. The general spraying amount is 150~350g active ingredient / hm 2 . 200-350g / hm for controlling wild oats 2 , effective from the early growth period to the leaf-segmentation and jointing stages. [0003] Flucarbasulfuron-methyl, 1H-1,2,4-triazole-1-carbamoyl-4,5-2H-3-methoxy-4-methyl-5-O-N-[[2-(trifluoro Methoxy) benzene] sulfonyl] - sodium salt, a sulfonylur...
