Peanut diseases mainly include stalk rot, root rot, blight, leaf spot, and blight. The pests mainly include insect pests such as blind borers, locusts, borerworms, leafminers, cotton bollworms, etc., and underground pests such as cockroaches, cockroaches, and wireworms. Peanut weeds mainly include Matang (common name known as Caotang), Amaranthus vulgare (also known as leeks, wild leeks), Tian Xuanhua, Purslane, Setaria viridis, Cyperus sphenanthera, Amaranthus (also called grayish grey) and other grasses. Weeds and broadleaf weeds.

Before spring sowing, 50 kg of mineral fertilizer, 30 kg of ternary compound fertilizer, 30 kg of large-sized ammonium bicarbonate, 50 kg of mineral fertilizer, 20 kg of ternary compound fertilizer, and 12 kg of urea are sown per acre before sowing. In areas without mineral fertilizers, 30 kg of gypsum powder (sweetened peanuts, calcium) and 3 kg of phoxim granules can be added. Use 100ml of trifluralin or chlorpromazine (also known as Lesch, Indigenin) per acre with 150ml of water, 30kg of water, and after spraying, turn ploughing or slanting 2 times and then flush every 2 meters. Ditch to facilitate later drainage and irrigation. Heavy hayfield combined with fertilizer spraying should spray EM500~750 ml per acre.

Spring peanuts should use peanut varieties with high yield, large fruit size and high oil content, such as Beijing No. 2, Green Oil No. 2, and Luhua 16 etc. 10 kg of seeds per acre (13 kg for machine sowing), 5000~6500 holes per acre, 2 seeds per hole, 4 hours before sowing, EM 150 ml, chlorpyrifos 20 ml, 2 kg water per acre seed Seed dressing. After mixing, it is stuffy and stuffy. After the peanuts are stretched, they can be sowed.

After the broadcast, the ground shall be leveled and covered with a plastic film. Fields without mulching film conditions can be used instead of mulching film after the peanuts have been raised with a 45-kilogram nazionate 1000-fold fluid. Peanut seedling mu spraying 15 kilograms that Qi Qi 1000 times, plus Japan EM50 ml; Peanut initial flowering period, spraying 30 kilograms per acre Na Qi Qi 1000 times, plus Japan EM 70 ml, add chlorpyrifos 50 ml, After 5 o'clock, stems and leaves are sprayed; Peanut full flower to the next cone period, spray once every 10 days 30 kg Na Qi Qi 500 times, plus Japan EM 100 ml, plus chlorpyrifos 60 ml or 30 kg love over 500 times , Kill 60 ml of scorpion. When controlling underground pests, such as larger populations of insects and more soil-fertilizer, 500 microliters of Phoxim Microparticle Suspension can be used in the 2 to 4 leaf stage of peanuts, and 90 kg of drops of water can be added to the ground. The sprayer can be used to spray nozzles. Drops, this method can effectively prevent peanuts underground pests, peanuts almost no harm from underground pests throughout the season, increase production by 20% to 60%.

PGA is a water soluble, biodegradable, non-toxic biopolymer produced by microbial fermentation. PGA is a sticky material first found in "natto", a fermented soybean. PGA is an unusual anionic, naturally occurring homo polyamide that is made of D & L glutamic acid units connected by amide linkages between alpha amino & gamma carboxylic acid groups.
Gamma-poly-glutamic acid (gamma-PGA) is a natural occurring, multi-functional, and biodegradable biopolymer.

It is produced through fermentation by Bacillus subtilis using glutamic acid. PGA is consists of glutamic acid monomers crosslinked between α-amino and γ-carboxyl groups, and the molecular weight of PGA is usually between 100~1000 kDa. It is water-soluble, edible and non-toxictowards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.
