Embodiment 1

[0031] Embodiment 1: (35% oil suspension concentrate)

[0032] Formula: tribenuron-methyl, 30%; florasulam, 5%; emulsifiers are selected from alkylphenol polyoxyethylene ether phosphate and nonylphenol polyoxyethylene ether, the dosage is 2% and 3% respectively; thickening Xanthan gum and bentonite were selected as the agent, and the dosages were 0.2% and 4% respectively; antifreeze ethylene glycol, 4%; soybean oil as filler, the balance.

[0033] 2. Wettable powder

[0034] Preparation method: According to the ratio of the formula in the example, add cyclobucilone and penoxsulam to the carrier, add surfactant and other additives, mix, jet mill and then mix to obtain wettable powder. The main equipment is a mixer and a jet mill.

Embodiment 2

[0035] Embodiment 2: (40% wettable powder)

[0036] Formula: tribenuron-methyl, 36%; florasulam, 4%; wetting agent sodium lauryl sulfate, 2%; Sodium dibutyl naphthalene sulfonate formaldehyde condensate, the dosages are 3.5%, 2% and 2% respectively; the carrier is white carbon black, 8%, kaolin, the balance.

[0037] 3. Water dispersible granules

[0038] Preparation method: Add tribenuron-methyl and florasulam into the carrier according to the ratio of the formula in the example, and add surfactant and other auxiliary agents therein, mix, air-jet pulverize, and then add 10-20% of water, Water-dispersible granules are obtained by kneading, granulating, drying, and sieving; or the pulverized powder is sprayed with water in a boiling granulator, granulated, dried, and then sieved to obtain the product. The main equipments are mixer, jet mill, kneader, extrusion granulator, drying room or fluidized bed drying, or boiling granulator, screening machine.

Abstract

The invention belongs to the field of agricultural herbicides, and in particular relates to a rice paddy herbicide containing a tribenuron-methyl and florasulam compounded composition. The invention aims to provide a compounded composition containing tribenuron-methyl and florasulam serving as active ingredients. By compounding, the prevention and control range is widened, the prevention and control effect is improved, and the pesticide consumption and agricultural cost are reduced. The technical scheme of the invention is that: in the compounded composition containing the tribenuron-methyl and the florasulam, the weight ratio of the tribenuron-methyl to the florasulam is 40:1-1:20; and the tribenuron-methyl and the florasulam account for 1 to 80 percent of the total weight of the compounded composition. The compounded composition has the advantages that: the synergism is achieved and the herbicide effect time is prolonged by compounding.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, in particular to a paddy field herbicide containing a compound composition of tribenuron-methyl and florasulam.
