An integrated control method for summer corn seedling pests and weeds

A technology for summer corn and seedling stage is applied in the field of integrated pest and weed control in summer corn seedling stage, which can solve the problems of weakening insecticidal effect and weeding effect, wasting manpower, material and financial resources, unable to achieve simultaneous control and the like, and achieves pest control. The weeding effect is remarkable, the yield is increased, and the manpower is saved.

Problems solved by technology

If insecticides and herbicides are used alone, the application time interval is too long, and the effect of simultaneous control cannot be achieved, and multiple application of pesticides wastes manpower, material and financial resources, while traditional organophosphorus insecticides are acidic. When used in combination with weakly alkaline herbicides, a neutralization reaction will occur during the compounding process, which will weaken the insecticidal and herbicidal effects at the same time

Embodiment 1

[0018] After corn sowing and before emergence, the corn field was sprayed with a medicinal solution containing atrazine, nicosulfuron and cypermethrin, which consisted of 48% acetochlor·atrazine suspoemulsion (active ingredient content: acetochlor 24 %, atrazine 24%), 4% nicosulfuron suspending agent and 2.5% cypermethrin emulsifiable concentrate mixed with water, the dosage per mu of each preparation is 48% acetochlor·atrazine suspoemulsion 200-250mL, 4% Nicosulfuron suspending agent 90-100g, 2.5% cypermethrin EC 90-100mL, mixed with water 25kg.

Embodiment 2

[0020] At the 3-5 leaf stage of corn seedlings, spray a medicinal solution containing nicosulfuron-methyl and cypermethrin to the corn field. The medicinal solution is prepared by mixing 4% nicosulfuron-methyl suspension concentrate and 2.5% cypermethrin EC with water. The dosage is 90-100g of 4% nicosulfuron suspension concentrate, 90-100mL of 2.5% cypermethrin emulsifiable concentrate, and 25kg of water.

Embodiment 3

[0022] At the 7-10 leaf stage of corn seedlings, spray a medicinal solution containing nicosulfuron-methyl and cypermethrin to the corn field. The medicinal solution is prepared by mixing 4% nicosulfuron-methyl suspension concentrate and 2.5% cypermethrin emulsifiable concentrate with water. The dosage is 90-100g of 4% nicosulfuron suspension concentrate, 90-100mL of 2.5% cypermethrin emulsifiable concentrate, and 25kg of water.

Abstract

The invention relates to an integrated prevention and control method of pests and weeds in summer corn seedling stage. After the corn is sown and before emergence, the corn field is sprayed with a medicinal solution containing atrazine, nicosulfuron and insecticides; or the corn seedlings are 3 At the ‑5 leaf stage, spray the cornfield with a liquid medicine containing nicosulfuron and insecticides; or at the 7‑10 leaf stage of corn seedlings, spray the cornfield with a liquid medicine containing nicosulfuron and insecticides ; The insecticide is a pyrethroid insecticide or emamectin benzoate. In the present invention, herbicide is weakly alkaline, and the diluent of pyrethroid insecticide or emamectin benzoate is close to neutral, and no reaction occurs after compounding. The combined use of pesticides not only does not weaken the insecticidal effect of insecticides and the weeding effect of herbicides, but also prevents insects and weeds from corn fields in a timely manner, and can also save manpower, material resources and financial resources; the present invention is safe for the growth and development of corn. No harm.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to an integrated prevention and control method for summer corn seedling pests and weeds. Background technique [0002] Corn is one of the important food crops. Due to the fact that summer maize has more wheat straw after no-tillage direct seeding, and the density of insect eggs is high. In addition, the growth period of summer maize is in a high-temperature and rainy season, and diseases, insect pests and weeds are also prone to occur, which will have a certain impact on the growth and development of maize. No harvest. The main insect pests at the seedling stage of corn include thrips, aphids, armyworms, and beet armyworms, which harm the stems and leaves of corn, causing twisted, yellow, and incomplete leaves, hollows at the base of the stems, and death of seedlings. The main weeds in the corn seedling stage are crabgrass, foxtail, Cyperus cyperi, goosegrass, bermudagrass, ...
