Problems solved by technology

Potato field weeds have complex grass phases, grass weeds and broad-leaved weeds are mixed with multiple types of weeds. The use of a single type of compound herbicide will show some defects and limitations, and it cannot completely solve the problem of potato field weeds. grass problem
At the same time, the use of herbicide varieties alone can easily lead to weed resistance

Embodiment 1

[0021] Example 1: 60% rimsulfuron-monosulfuron-methyl water-dispersible granule.

[0022] rimsulfuron-methyl 10%, monosulfuron 50%, sodium lauryl sulfate 5%, polycarboxylate 4%, sticky powder 2%, sodium chloride 2%, urea 3%, potassium sorbate 2% , kaolin make up to 100%. The above-mentioned materials are weighed in proportion, put into a mixer and mixed evenly, then pulverized by an ultra-fine jet mill, kneaded, and then added to a fluidized bed granulation dryer for granulation, drying, and screening to obtain 60 % rimsulfuron monosulfuron monosulfuron water dispersible granules.

[0023] This embodiment is used to prevent and treat weeds in potato fields: 60% rimsulfuron-monosulfuron water-dispersible granules are used respectively to spray 100g a.i. / ha on the 5-leaf stage of weeds with watered stems and leaves, and investigate the control effect 20 days after the medicine 98.05%; the control effect of 60% rimsulfuron-methyl water-dispersible granules under the same condit...

Embodiment 2

[0024] Example 2: 48% rimsulfuron-monosulfuron wettable powder.

[0025] rimsulfuron-methyl 8%, monosulfuron 40%, sodium dodecylbenzenesulfonate 6%, sodium lignosulfonate 4%, NNO 5%, talcum powder 2%, white carbon black 2%, attapulgite Soil replenished to 100%. The above-mentioned materials are weighed in proportion, put into a mixer, mixed evenly, and then crushed by airflow, and then 48% rimsulfuron-monosulfuron wettable powder is obtained.

[0026] This embodiment is used to prevent and treat weeds in the potato field: 48% rimsulfuron-monosulfuron wettable powder is used respectively in 100g a.i. / ha to spray watered stems and leaves at the 5 leaf stage of weeds, and the control effect of 20d investigation after the medicine is 96.84%; the control effect of 48% rimsulfuron-methyl wettable powder under the same conditions was 85.27%; the control effect of 48% monosulfuron-methyl wettable powder was 68.07% under the same conditions. It can be seen that the combination of rim...

Embodiment 3

[0027] Example 3: 30% rimsulfuron-monosulfuron suspension concentrate.

[0028] rimsulfuron-methyl 5%, monosulfuron 25%, Nongru 602# 8%, oleamidoanisole sulfonic acid 5%, alkylphenol formaldehyde resin 6%, polyoxyethylene ether sulfate 4%, bentonite 3%, silicone 2%, glycol 4%, deionized water to make up to 100%. The above-mentioned materials are weighed in proportion, put into a mixer and mixed evenly, then put into a sand mill for grinding, and undergo high shearing to prepare 30% rimsulfuron-monosulfuron suspension concentrate.

[0029] This embodiment is used to prevent and treat weeds in potato fields: 30% rimsulfuron-monosulfuron suspension concentrate is used respectively at 100ga.i. / ha to spray watered stems and leaves at the 5-leaf stage of weeds, and the control effect is investigated 20 days after the drug 98.95%; the control effect of 30% rimsulfuron-methyl suspension concentrate under the same conditions was 87.33%; the control effect of 30% monosulfuron-methyl su...

Abstract

The invention relates to a weeding composition containing rimsulfuron and monosulfuron ester. Effective components comprise the rimsulfuron and the monosulfuron ester; the weight part ratio of the rimsulfuron to the monosulfuron ester ranges from (20 to 1) to (1 to 20); the weeding composition is used for preventing and controlling annual weeds of a potato field and has a remarkable synergistic effect; a utilization effect is improved, a prevention and control spectrum is expanded and the utilization dosage is reduced; influences, caused by pesticide, on an ecological environment are reduced;resistance management of the weds is facilitated; the weeding composition has relatively great economic benefits and social benefits.

Description

technical field [0001] The invention relates to a compound pesticide combination and its application technology. The combination of effective components rimsulfuron-methyl and monosulfuron is applied to control weeds in potato fields. Background technique [0002] Rimisulfuron-methyl, a compound inhibitor of sulfonylurea amino acids, is absorbed by roots, stems, and leaves, and is transmitted to meristems. By inhibiting the biosynthesis of essential valine and isoleucine, cell differentiation and plant growth are achieved. stop. [0003] Monosulfurate is a sulfonylurea herbicide independently developed by the National Engineering Research Center of Pesticides (Tianjin) (Nankai University). It is environmentally friendly and has moderate application cost. It can effectively control broad-leaved weeds such as Artemisia sorenzo, shepherd's purse, and quinoa, which are the main weeds in wheat fields, and has high herbicidal activity. [0004] Chemical weeding is one of the mai...
