(1) Acetochlor: Also known as chlorpyrifos. It is 50%, 86% emulsifiable concentrate, mainly for controlling annual weeds, and has certain effects on cockroaches, cockroaches, comfrey, and purslane, and is ineffective for perennial weeds. 50% acetochlor ECG planted in the field of 78 ~ 100 grams per acre, 45 ~ 66 grams of film field, 50 ~ 70 kg water, sprayed evenly on the soil surface. After the peanuts are emerged, they can be mixed with the grass to apply the sprayed ground, which not only inhibits the weeds that have not been unearthed, but also kills the weeds that have been unearthed and improves the control effect. The dosage should be noted to determine the upper and lower limits depending on the soil organic matter content. Soil herbicides with high organic matter content have poor activity, and the dosage is high, and the upper limit is taken. Otherwise, the lower limit is taken.
(2) Purifying grass: 50%, 80% wettable powder. The herbicide is a systemic absorption type, and the medicine can be absorbed from the roots, or can be infiltrated into the body from the stems and leaves, and is transmitted to the green leaves to exert the herbicidal action. It mainly controls annual broadleaf weeds, grass weeds and sedge weeds. It is a pre-emergence herbicide. Before the seeding of peanuts, 50-72 grams per acre, 60-70 kilograms of water, evenly sprayed on the soil surface, and the grass can also be mixed with alachlor, the effect is very good.
(3) Fluorine: Also known as Fluorine. It is 48% emulsifiable concentrate, 2.5%, 5% granules. The herbicide is absorbed by the process of germination and growth of weed seeds through the soil layer, and is a selective pre-emergence soil treatment agent. It is suitable for covering peanut fields. It should be mixed immediately after application in the field to prevent volatilization and photolysis. Mainly to prevent grass weeds, peanuts before sowing, spray the ground with liquid medicine, 48 ~ 72 grams per acre.
(4) Cover grass can be: 12.5%, 24% emulsifiable, post-emergence selective herbicide. It has systemic conductivity, is quickly absorbed by weed blades after stem and leaf treatment, and is transported to the whole plant, inhibits the meristem of stems and roots and causes weeds to die, and controls the annual and perennial grass weeds before heading. It works well and is not effective against broadleaf weeds and sedges. Peanuts in the second to fourth leaf stage, grasses weeds from three to five leaves, 5 to 8 grams per acre, 60 to 70 kilograms of water sprayed on weed stems and leaves, under drought conditions can be appropriate to increase the dose.
(5) Pusat: Also known as oxacilazole. It is a 5% water agent, selective pre-emergence and early post-emergence herbicides. It is suitable for legume crops to control annual, perennial grass weeds and broadleaf weeds. It has a wide spectrum of herbicides and is sprayed on the seedlings before seeding. The surface of the soil can also be treated after the emergence of peanuts. For plots with high content of clay or organic matter, the dosage should be increased; when the content of sandy soil or organic matter is low, the dosage should be less, and the amount of acetochlor per acre should be used. It can be mixed with herbicide or acetochlor to improve the efficacy.
(6) Pai Dan: also known as bentazon. It is a 48% liquid agent and a 25% water agent. It is a contact-emergence herbicide. The agent is mainly absorbed through the stems and leaves, and the conduction effect is small. Therefore, the liquid should evenly cover the weed leaves when spraying. It can prevent sedge and broadleaf weeds and is ineffective against grass weeds. When mixed with liquid nitrogen fertilizer, the herbicide activity is increased by 2 to 4 times. Apply at the time of 2 to 4 compound leaves of peanuts, and apply at most once. The usual amount per acre is 76.5-96 grams. When using high temperature and sunny days, the herbicidal effect is good.
(7) Sodium pentachlorophenol: also known as sodium pentachlorophenolate. It is a 80%, 95% powder, 25% granule, and is a herbicide-type herbicide. Annual weed seeds die when they contact the drug layer during germination. Before the seedlings were planted, the seeds were applied with 56.3 to 83.3 grams per acre, and the ground was sprayed with water. Note that this agent cannot be used in sandy soil to prevent the liquid from infiltrating into the soil and causing harm. It is highly toxic and should not be in contact with the skin during application.
(8) Weed Burning: Also known as Dakker, Breegang. It is a 21.4% aqueous solution and is a selective contact herbicide. It is suitable for controlling broad-leaved weeds such as peanuts, soybeans, etc., such as purslane, yarrow, iron leeks, alfalfa, Xanthium, etc., and is also effective for grass weeds in the post-emergence one to three-leaf stage. During the first to third leaf stage of peanuts, the broadleaf weeds are used in the three to five-leaf stage, and the dosage is 24 to 32 grams per mu. It is mixed into the liquid and evenly sprayed on the stems and leaves of the weeds. Killed and used in succession, weeding thoroughly.
(9) Herbamin: 25%, 50% wettable powder, 20% emulsifiable concentrate, is a selective systemic and contact herbicide. Dry soil in the pre-emergence soil treatment after crop sowing, pre-emergence pre-emergence or early post-emergence (first to third-leaf stage), 180-370 grams per acre, can be used for crop fields such as peanuts, cotton, soybeans, corn, wheat, etc. Gramineous weeds and certain broadleaf weeds, such as valerian, crabgrass, goosegrass, foxtail, plantain, etc.
(10) Take the net: also known as Shouheding, Acacia. It is a 20% emulsifiable concentrate and a 12.5% ​​motor oil emulsifiable concentrate. It is a selective and strong internal-leakage type stem and leaf treatment agent. The agent can be quickly absorbed by grass weeds and transmitted to the apical and internode meristems, causing their cells to be destroyed. The application of the medicament into the soil is quickly decomposed and has a short-lasting effect in the soil, and it is suitable as a stem and leaf treatment agent. It can be applied during the period of 2 to 3 tillers of grass weeds, and the amount of peanut field is 13 to 26 grams per acre.
