Embodiment 1

[0015] Example 1: Indoor toxicity determination of butachlor, clomazone and bensulfuron-methyl on crabgrass and goosegrass

[0016] Weeds tested: crabgrass, goosegrass.

[0017] Drugs to be tested: atrazine original drug, mesotrione original drug, bialaphos original drug; commercially available.

[0018] Test method: the indoor pot test method is adopted. The test soil is the special test soil collected from plots without medication. Use pots to fill the soil to 3 / 4 height, make a number of holes with a diameter of 0.3-0.5 cm at the bottom, and put the pots into plastic pots filled with shallow water layers. After the soil is completely moist, sprinkle the weed seeds after soaking and germination evenly into the pots (20 per pot), cover with 0.5-1.0 cm thick mixed sand and fine soil, and replenish water regularly to keep the soil moist. Dingmiao when the weeds emerge neatly.

[0019] Treatment and investigation methods: When the weeds grow to the 2-3 leaf stage, use a singl...

[0028] Preparation 1: 20% atrazine·mesotrione·bialaphos suspension concentrate

[0029] Atrazine 10%, Mesotrione 8%, Bialaphos 2%, Alkyl Naphthalene Sulfonate Formaldehyde Polycondensate 8%, Sodium Lauryl Sulfate 6%, Xanthan Gum 4%, Ethylene Glycol 3%, bentonite 2%, silicone 3%, water to make up to 100%.

[0030] Preparation 2: 36% atrazine·mesotrione·bialaphos suspension concentrate

[0031] Atrazine 15%, Mesotrione 6%, Bialaphos 15%, Sodium Lignosulfonate 5%, Dioctyl Sodium Succinate 7%, Magnesium Aluminum Silicate 3%, Ethylene Glycol 4 %, white carbon black 4%, organic silicon 3%, water to make up to 100%.

[0032] Preparation 3: 28% atrazine·mesotrione·bialaphos suspension concentrate

[0033] Atrazine 10%, Mesotrione 8%, Bialaphos 10%, Sodium Lignosulfonate 3%, Sodium Lauryl Sulfate 6%, Xanthan Gum 3%, Glycerin 2%, Bentonite 3%, silicone 3%, water to make up to 100%

Embodiment 3

[0034] Embodiment 3 field control effect test

[0035] Experimental area: sugarcane field base in Fusui County, Chongzuo City, Guangxi. The variety of sugarcane is Xintaitang No. 22. Weeds in the field are crabgrass, goosegrass, sorrel, split-leaf morning glory, fish yellow grass, and syringa.

[0036] Test method: set 3 chemical treatments, 1 blank control, repeat 4 times; each plot area is 50m 2 , arranged randomly. Weeds are sprayed at the 2-3 leaf stage. The fresh weight control effect of weeds was investigated 14 days after spraying, and the phytotoxicity of each treatment on sugarcane was visually observed at 7 and 14 days after spraying.

Abstract

The invention provides a weeding composition containing atrazine, mesotrione and bialaphos. The active ingredients of the weeding composition comprise atrazine, mesotrione and bialaphos, and the mass ratio of atrazine to mesotrione to bialaphos is (1-10): (1-5): (0.1-5). The weeding composition disclosed by the invention has a remarkable synergistic effect and can be used for preventing and controlling weeds in a sugarcane field by an unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the field of pesticide herbicides, in particular to a herbicidal composition containing atrazine, mesotrione and bialaphos and its application. Background technique [0002] Atrazine is a triazine compound, it is a systemic selective pre-emergence soil treatment agent, and it can also be sprayed on stems and leaves after emergence. It is mainly absorbed through the roots of plants and conducted upwards, inhibiting the photosynthesis of plants, causing them to die and kill The grass spectrum is wide, and it can control a variety of annual grasses and broad-leaved weeds. [0003] Mesotrione, a triketone compound, is a broad-spectrum pre-emergence and post-emergence herbicide that can inhibit hydroxyphenylpyruvate dioxygenase. It has contact action and persistent effect, and can effectively control the main broad-leaved Grasses and some grasses. [0004] Bialaphos is a tripeptide natural product isolated and purified from Strept...
