Peanut stalk rot, commonly known as rotten neck disease, is distributed throughout the country's flower production areas. It usually occurs in the middle and late stages. It quickly wilts after the illness and is later known as susceptible. Fruit pods are often rot or dissatisfaction with species, causing serious losses. The incidence of fields is generally 20% to 30%, and severe cases reach 60% to 70%, even without crops.
First, the symptoms of bacteria from the cotyledon or larvae invade the plant, resulting in yellow-brown water spots in the root and neck lesions, after dark brown, causing root tissue decay. When in wet conditions, the diseased part produces conidiospore (ie, black small projections), the epidermis of the diseased part is easily peeled off, and the fibrous tissue is exposed. When the environment is dry, the epidermis of the diseased area is sunken and closely adheres to the stem. After the adult stage is affected, the whole plant withers in about 10 to 30 days. The diseased part is often attached to the ground at the base of the stem, and sometimes the main stem and collateral branch appear dead in stages. .
Second, the incidence of pathogenic bacteria mainly in the seeds and soil in the sick plants overwintering, become the source of disease next year. If the diseased strain is used as a beverage, or if the manure is used to feed the animal's stool, as well as mixed fertilizers produced by mixed diseased plants can also spread. Spreading in the fields is mainly due to rainwater runoff in the fields, followed by strong winds, but the carrying of germs can also spread during agricultural operations. In rainy and wet years, especially during the harvest season, the harvest rate of seeds is high. Therefore, it is not only the main culprit of the disease, but it can also be transmitted through long distances through introduction.
Third, control methods
1. Prevent seed from mould and ensure seed quality.
(1) Harvest at a proper time to avoid moisture and mold
(2) Dried seeds to ensure that the moisture content does not exceed 10%;
(3) Safe storage, pay attention to ventilation and moisture protection;
(4) Must not use mold seed, spoilage seed sowing;
(5) Peanuts with peanuts sown in early time had a lighter incidence;
(6) Selection of disease-resistant varieties.
2. Rational rotation, preferably with wheat, sorghum, corn and other crop rotations;
3. Apply rotting fertilizer and strengthen field management.
4. Chemical control: Use 25% or 50% carbendazim wettable powder, according to the seed weight of 0.3% to 0.5% seed dressing or according to the seed amount of 0.5% to 1% of the pharmaceutical solution mixed with water soaking, to be able to submerge Seeds prevail, soak for 24 hours and sow.
All water based products have plenty of nutrients and water to support microbe growth under favorable conditions. Microbes invade water based products from multi-point sources, such as contaminated raw materials, poor plant hygiene, untreated water, and not properly preserved recycling materials. While adding in-can preservatives into the products should not excuse a factory from Good Manufacturing Hygiene Practices (GMHP), proper use of in-can preservatives coupled with GMHP can dramatically minimize the chance of microbial tolerance development, and assure unspoiled products to customers.
Biocides formulators often use several types of in-can preservatives as active ingredients in their biocidal products for various industrial water based products. One of these active ingredients is benzisothiazolone (BIT). It has several distinct performance advantages, including good stability at high pH, good stability in the presence of reducing agents, and broad spectrum of activities against many microbes.Sunshine Biotech supplies to all industrial biocides formulators with high quality BIT technical ingredients. Besides of BIT, we also provide its derivative, like BBIT, MBIT etc.
