What is the disease of watermelon roots?

There are two possible sources of watermelon seedling root lumps. First, the fertilizer contains chloride ions. If the potassium fertilizer used in the compound fertilizer is potassium chloride, the concentration of chloride ions in the growing environment of the watermelon is too high, and the above symptoms will occur; if the first one is ruled out, In this case, the second may be root-knot nematode disease, root-knot nematode disease commonly known as watermelon cancer, watermelon, melon fibrous roots or lateral roots after the disease produces tumor-like root knots, underground root knots, such as mild symptoms The performance of the aboveground parts was not obvious. The severely ill strains had poor fertility. The leaves wilted at noon, or gradually became dry, and the plants were short, affecting fruitfulness. When the onset was serious, the whole field died. Since nematodes are very difficult to kill in the soil, insecticides cannot penetrate into the soil. Nematodes are animals. They move around and are difficult to eradicate. Watermelon root knot nematode disease mainly has the following methods of prevention and control:
First, give up the use of diseased watermelon seedlings, re-cultivation, otherwise it will spread nematodes, transplanting to the field after the control is even more difficult. The original soil, manure, and seedbed cannot be used when raising the seedlings again;
Second, the diseased melon seedlings do a good job of pest control, when transplanting, acupuncture or irrigation pesticides;
Third, the prevention and treatment of diseased seedlings is to use avermectin, phoxim, trichlorfon, Tiannuo line net, Pudi grams and other pharmaceutical application or irrigation, different concentrations of different pesticides can be prepared according to the instructions.

Biocide Technical Ingredients

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.
