Peanut Diseases and Pest Integrated Control Technology

1. Prevent winter plowing and deep plowing before sowing to reduce pests and diseases. The implementation of crop rotation, selection of disease-resistant varieties, treatment of remaining peanuts, reduce pathogens and other measures. Combining early spring farming, treating soil with fumigants, and controlling root knot pests. To ensure the safety of people, livestock and crops, it must be applied one month before sowing.
Second, sowing prevention
1, control underground pests. Combining groundnut seeding, prevention and control of the underground pests caused by overwintering damage, such as gold tortoiseshell turtles and golden worms, 2.5 kg of phoxim granules per mu, or 0.1 to 0.15 kg of phlophosin EC or 40% water-containing phosphorothioate EC, 30 kilograms of fine soil or 2 kg with wheat bran; sprinkled in the sowing ditch. Prevention of peanut root knot nematodes, feeding turtle shells and leaves of the gold tortoiseshell, and pests and other underground pests and aphids and other pests on the ground, available 10% grams of phosphorous 3 kg, or 10% phosphoric powder 0.5 kg, optionally a particle Cover species, or sprinkle with seeding trenches. Use 3% seed coating No. 4 emulsion to coat 2% of the seed amount, or use 50% phoxim emulsion 50 ml water 5 kg seed dressing 50 kg to control underground pests such as earthworm, golden tortoise shell, and golden needle grasshopper And locusts and other pests on the ground.
2, control peanut wilt. Can be used 50% carbendazim WP according to the seed amount of 0.3% seed dressing, germination of the seed buds exposed when appropriate. Or use 50% carbendazim WP to soak seeds in 0.5% of seeds for 24 hours. After the seeds are soaked, the seeds will be sowed. The main prevention measures include peanut stalk rot, black mold, blight, and blight.
3, prevention of peanut root knot nematode disease. It can be used to increase 1500 times the efficiency of Arroz microemulsion 1500 times, or avermectin 1000 times the liquid, 100 ml per pour, sow and sow every time. Or use 2 kilograms of physical protective agent nontoxic high fat film or 2.5 kilograms of farmer No. 1 marine biological products per acre.
4, prevention and treatment of peanut virus disease. The prevention and control method is mainly to establish a seed breeding base for the production of non-toxic seeds, or to choose to reduce the seed poisoning rate, and pay attention to the prevention and control of aphids to prevent transmission during the growth period. The sowing period is postponed as appropriate to reduce the hazards of cold temperatures and avoid disease conditions.
Third, seedling control
1, control locusts. The prevention and control at the seedling stage was focused on the fact that the peanuts were not applied with the systemic absorption agent or the effect was poor after the planting. The prevention and control methods are as follows: When it is found that pests such as aphids, leafhoppers, thrips, and chafers are harmful, they can be sprayed with imidacloprid wettable powder 4000 times solution and 20% Guangkewei EC 1000 times.
Protect and use natural enemies. There are 37 species in the world of peanut aphids, such as ladybugs, grasshoppers, food flies, and bees, which can control aphid damage when the number of dams is about 4 heads and the scoop and turn ratio is 1:100-120.
2, control of adult worms. The best method of prevention and control: that is, in mid-June, when the soil is moist before rain or after rain, use 10% phosphoric acid powder 1kg or 5% methylisotriphos granules 2kg per acre, etc. Multi-agent, directly or even with 5 kg of fine soil mix, concentrated and evenly applied to the soil on the main root of peanuts, you can completely control the tortoiseshell and the endangering pods, and at the same time, treat the golden threadworm and mesh. A variety of underground pests.
In order to protect the use of earthworms in the natural dino-pitting land bumble bee, honey plants such as kidney beans can be planted around the peanut field. Peanut fields are planted with ramie traps.
IV. Prevention and treatment in the middle and later stages
1, prevention and control of phlegm. In early July and mid-July, the time of hatching and the young larvae were controlled in time. Apply 10% imidacloprid WP 25 g or 14% chlorpyrifos granules 1.5 kg per acre, add 15 kg of sandy soil and mix well and apply in Kaigou. Watering in time after application is better. Can also be used 50% chlorpyrifos EC or 10% imidacloprid wettable powder 1000 times irrigation pier.
2, control leaf spot. It is an essential production increase measure for peanuts. Before the onset of disease, spraying 1:1:200-fold Bordeaux mixture, or 200-fold solution of Bordeaux liquid plant protection agent (powder), or 70% mancozeb.
After onset, use 50% carbendazim 800 times, or 50% thiophanate-methyl 1000 times, spray 75 kg per acre, spray once every 10-15 days, spray 2-3 times in total, and spray uniformly .
Use Antibiotics for agricultural resistance 120 and physical protective agents for non-toxic high-fat lipid membranes each 150g/mu, or use mesogenic bacteria 20ml/mu, or Jinggangmycin 100g/mu, or use sulfur suspending agent 15~20g/ Mu, watered 60~75 kg/mu, foliar spraying, not only can prevent leaf spot disease, but also can cure other fungal diseases.
3, control of cotton bollworm. H. armigera damages peanuts in the second and third generations, and it is the third-generation hazard. When Baidun Peanut has 30 young instars or 30 insects, spray 20% Guangkewei Emulsion 1000 times, or 2.5% dichlorvos 1500 times, or 50% phoxim EC 800 times, or 50% boll Conservative oil 800 times and other prevention and treatment, while simultaneously treatment of big moths, bridges and aphids.
In the middle and late stages, insect pests such as Helicoverpa armigera, bridge-building moths, big moths, and Spodoptera litura, were sprayed with “BT” (Bacillus thuringiensis) before the third instar.
4, prevention of flower rust disease. Rust is an explosive epidemic in Shandong. It began to happen in mid-August. Can spray 90% of the enemy rust sodium or 70% of chlorothalonil 600 times, spray once every 7-10 days, and even spray 2-3 times. Each spraying liquid 75 kg/mu, can effectively prevent the development of the disease.
Fifth, harvest control. Combine peanut harvesting and re-harvest, pick up cockroaches or gold tortoise shells, reduce pest density, and reduce hazards in the following year. During the process of peanut harvesting, drying, and storage, ventilation and drying must be maintained to prevent moldy pods. Mildew seed is the main cause of peanut wilt disease. Peanut root knot nematode disease occurs in severe plots. It is necessary to deep-root sick roots or winter plowing to kill pathogens by drying. Clears field diseases and reduces the occurrence of various diseases such as leaf spot, stem rot and rust in the following year.
