Embodiment 1

[0016] Biological Assay Example 1: Indoor Toxicity Test of Pinoxaden and Monosulfuron-methyl on Weeds in Wheat Field

[0017] Test objects: pig scorpion, shepherd's purse, wild oats, soda

[0018] Greenhouse pot method was used to measure the activity of pinoxaden and monosulfuron-methyl on weeds. At the same time, it was compared with pinoxaden and monosulfuron-methyl. The active components were treated with 0.1% Tween-80 aqueous solution. Use a plastic nutrient bowl with a diameter of 9 cm, which contains air-dried top soil collected from the farmland, and keep the soil moist by supplying water from the bottom, sow weed seeds with full and uniform grains, and cover the soil with 0.5 cm. There were 15 weeds in the pots, and 5 pots of each weed were treated. When the weeds are suitable for the test, spray in the PWT-510 spray tower (the accurate spray area is 0.02m 2 , spray liquid 10ml, contrast spray 0.1% Tween-80 aqueous solution. Eighteen days after the treatment, the f...

Embodiment 2

[0030] Example 2: 20.4% pinoxaden monosulfuron suspension concentrate

[0031]

[0032] Active ingredients, dispersants, wetting agents, thickeners, antifreeze agents, preservatives and water are mixed evenly according to the ratio of the formula, and 20.4% pinoxaden is obtained after grinding and / or high-speed shearing. Monosulfuron-methyl suspension concentrate.

[0033] This embodiment is applied to the control of weeds in wheat fields. Dilute and spray 20.4% pinoxaden monosulfuron-methyl suspension concentrate (the concentration of pinoxaden-ethyl active ingredient is 40 μg / ml, the concentration of monosulfuron-methyl active ingredient is 0.8 μg / ml) with water, 7 days and The 20-day control effects were 97.5% and 96.9%, respectively. The contrast agent 5% pinoxaden EC (active ingredient concentration is 50 μg / ml) and 10% monosulfuron-methyl suspension concentrate (active ingredient concentration is 50 μg / ml) are used in the same way, after 7 days and 20 days after the...

Embodiment 3

[0034] Example 3: 11% pinoxaden monosulfuron suspension concentrate

[0035]

[0036]

[0037] Mix active ingredient, dispersant, wetting agent, thickener, antifreeze, preservative and water according to the proportion of the formula, and grind and / or high-speed shear to obtain 11% pinoxaden. Monosulfuron-methyl suspension concentrate.

[0038]This embodiment is applied to the control of weeds in wheat fields. Dilute the 11% pinoxaden monosulfuron suspension concentrate (the concentration of pinoxaden active ingredient is 40 μg / ml, the concentration of monosulfuron-methyl active ingredient is 4 μg / ml) and add water to dilute the seedling spraying, 7 days after the medicine and 20-day control effects were 95.8% and 96.8%, respectively. The contrast agent 5% pinoxaden EC (active ingredient concentration is 50 μg / ml) and 10% monosulfuron-methyl suspension concentrate (active ingredient concentration is 50 μg / ml) are used in the same way, after 7 days and 20 days after the...

Abstract

The invention discloses a weeding composition, which comprises active ingredients of pinoxaden and monosulfuron according to a mass ratio of 50:1 to 1:50. The composition provided by the invention has an obvious synergism effect, and can be used for wheat land weed prevention and control.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition containing pinoxaden and its application for controlling weeds in wheat fields, belonging to the technical field of pesticides. Background technique [0002] Wheat and barley are important food crops, and wheat is the most important. Wheat is a general term for Triticum plants, a gramineous plant widely planted around the world, rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin and vitamin A, etc. , is the second largest food crop in the world. In my country, wheat is one of the three major food crops, occupies an important position in all food crops, and is the foundation of my country's agriculture. However, most of the wheat fields in my country have suffered from weed damage to varying degrees. These weeds are of many types, widely distributed, vigorous in growth, and cover a large area per plant. Weakness directly affect...
