Embodiment Construction

[0008] 1. Implement crop rotation. Fields with mild diseases are rotated every other year, and fields with severe diseases are rotated for 3 to 5 years. Rotate with gramineous crops such as wheat and corn, and avoid interplanting and interplanting with soybeans and sweet potatoes.

[0009] 2. Collect and manage the seeds well. Peanuts used as seeds should be harvested in time, dried in the sun, and stored in a ventilated and dry place, protected from moisture and mildew.

[0010] 3. Seed treatment before sowing. Select disease-free seeds before sowing, dry the seeds, and carry out seed treatment at the same time. You can use 50% carbendazim wettable powder with 0.3 to 0.5% of the seed weight for seed dressing or use 2.5% Shileshi seed coating agent at a ratio of 1:500 (drug : species) for coating.

[0011] 4. Deep plowing to improve the soil. After the peanuts are harvested, the land shall be plowed deep in time to eliminate some overwintering pathogens, and the ground sh...

Abstract

The invention aims at solving the problems that the root rot and the stem rot of the peanut seriously happen on the continuous cropping land parcels; the peanut is weak in growth, bad in disease resistance and serious in morbidity in the land which is shallow in soil layer, arenaceous and low in fertility; the spring-sown peanut is serious in morbidity of root rot on the early-sown land parcels; and the root rot is serious in the year which is overcast and rainy, and high in humidity during seedling stage, the root disease, the stem disease and the fruit disease of the mulching film peanut commonly happen, wherein the common disease incidence reaches 3%-15%, 80% seriously and the like. According to the technical effect of the invention, the disease propagation spreading paths such as the facts that the soil carries disease germs, the seed carries disease germs and the manure carries disease germs can be solved, the peanut growth vigor can be improved, and the disease resistance can be improved.

Description

technical field [0001] The invention relates to the field of peanut planting, in particular to a peanut disease prevention technology. Background technique [0002] At present, due to the continuous planting of peanuts, soil-borne diseases such as peanut root rot and stem rot have become common diseases, which are very common and serious hazards, especially in heavy-cropping plots, which have increased year by year, seriously affecting the yield and quality of peanuts. Its harmful symptoms are as follows: [0003] 1. Peanut root rot. Commonly known as "rat tail", it can occur in all growth stages. Peanuts are infected after sowing and before emergence, infecting the newly germinated seeds, resulting in rotten seeds without seedlings; if the seedlings are damaged, the main root will turn brown, and the plant will wither; if the adult plant is damaged, there will be sunken long strips of brown lesions on the main root rhizome, and the roots will rot and peel off easily. , n...
