How to use chemical weeding for peanuts?

How to weed peanuts chemically? please brief us on Peanut is one of the main economic crops. Weeding is the most time-consuming in the cultivation process. The weeds with greater harm on peanut ground include crabgrass, Setaria, Euphorbia, Cyperus rotundus, Echinochloa, etc.; the broad-leaved weeds include Echinacea, Celosia, Echinochloa, Sonchus, Convolvulus, Camelina, Polygonum, Chenopodium, Amaranthus, Bean and Solanum. According to the characteristics of many kinds of weeds and different growth periods in peanut field, different herbicide varieties should be selected according to different weeds in different stages of peanut planting, and proper application treatment in due time can obtain better results. Several common chemical weed control techniques for peanuts are briefly described as follows: 1. Herbicides before emergence after peanut sowing After peanut sowing, different herbicides are selected to spray topsoil according to different weed types before emergence, covering to form a pesticide film layer, and closing the ground surface for weeding. 1. Peanut fields with more monocotyledon weeds For every 667 square meters, evenly spray 72% Dur 100- 150ml with 40kg water, or evenly spray 50% Acetochlor 150- 200ml with 40kg water, or spray 48% Lasso emulsion 100g mixed with 25% Diuron WP 100g with 40kg water. 2. Peanut fields with monocotyledonous and dicotyledonous weeds symbiotic 4g of 50% quick-harvest plus 60ml of 90% Horace were sprayed with 40kg of water per 667 square meters. Or three days before peanut sowing (or three days before sowing to germination), spray 20% Gramoxone 120- 180ml with 30 - 45kg water evenly on weed stems and leaves or ground surface. Saline-alkali land, sandy dry land, sandy loam with low organic matter content, especially dry soil or waterlogged land generally do not use pre-emergence soil treatment for weeding, but should adopt post-emergence stem and leaf treatment. 2. Post-seedling stem and leaf treatment, After peanut sowing, closed weeding on the ground before germination cannot be carried out due to busy agricultural work or climatic factors. After peanut and weed emergence, grass weeds can be sprayed at 2-4 leaf stage and broadleaf weeds at 5 - 10 cm height. 1. Gramineous weeds 6.9% Weiba 40- 50ml, or 10.8% high-effect clover 25- 30ml, or 15% fenvalerate 40- 50ml, or 20% fenvalerate 30ml, water 40kg stem and leaf spraying, can control annual grass weeds. 2. Broadleaf weeds 8-10 ml of 24% Kokuole or 60 ml of 25% Fuwei and 40 kg of water per 667 square meters can effectively control common broadleaf weeds. Peanut field herbicide Kecaoxing (peanut treasure), which is a mixture of gramineous weeds and broad-leaved weeds, can be used before 2~3 compound leaves of peanuts and before sealing ridges. Application method: (1) Peanut 2~3 compound leaves, weed 1~3 leaf stage, 40~50 ml of Kecaoxing mixed with 40 kg of water for each mu shall be sprayed evenly. (2) Peanut 4 compound leaves to before ridge sealing, weed 4~6 leaf stage, mu with 50~ 65ml of Kecaoxing mixed with 40kg of water evenly sprayed. Or choose a mixture of the two herbicides.
