Vegetable Seed Disinfection Suppression Seed Disease

Disinfecting the vegetable seeds before sowing can inhibit the diseases of the species, increase the germination rate and seedling rate of the seeds, and enable the vegetables to obtain higher yield and economic benefits. Sterilization of vegetable seeds often uses the following methods:

Warm water soaking method. The seeds were soaked in warm water at 55[deg.] C. (the lethal temperature of the pathogen was 55[deg.] C.) and the amount of water used was 5-6 times the seed. When soaking seeds, keep stirring the seeds and supply warm water in time to maintain the water temperature of 55°C. After soaking for 10 minutes, add cold water to reduce the water temperature. This method can prevent and cure a variety of diseases, such as blight of eggplant, brown leaf disease, bacterial disease of tomato, spot blotch of celery, spot disease, anthrax of cucumber, and black spot disease.

Hot water hot seed method. Put the dried seeds in a container, first immerse the seeds in cold water, then stir it with hot boiling water, so that the water temperature reaches 70-75°C, keep for 1-2 minutes, and pour cold water to reduce the water temperature to 55°C. Maintain 6-8 minutes. The method can make the mosaic virus passivation, but also has a bactericidal effect.

Dry heat treatment. The seeds are placed under dry heat treatment at 50-60°C for 15-20 minutes. After treatment, tomato seeds can not only kill germs, but also increase the germination rate. The cucumber seeds are treated with dry heat for a short period of time to control keratoses and scabs. Melon seed dry heat treatment, in addition to sterilization, but also increase production.

Drug seed dressing method. The dosage of the medicament is 0.1% to 0.5% of the seed, and the pesticide and the seed should be fully mixed during the seed dressing. Control of cucumber damping-off can be used 0.3% ~ 0.4% concentration of cuprous oxide powder seed dressing; control of tomato and cucumber damping-off can be used 0.3% concentration of 70% of enemy powder dressing; control of bean anthrax available 0.2% concentration of 50 % Carbendazim seed dressing; control of bean leaf burn disease can be seed dressing with 0.3% concentration of 50% thiram WP.

Potion soaking method. Before soaking, the seeds are usually soaked in clean water for 4 to 6 hours and then immersed in the medicine. The medicines and methods for soaking seeds in common medicines are soaked with formalin 100 times for 15 to 20 minutes, then the seeds are removed and fumigated for 2 to 3 hours, and then rinsed with water to reduce early blight of tomato and anthrax on eggplant. Fusarium Wilt and Brown Spot Disease; soaking seeds with 10% trisodium phosphate or 2% sodium hydroxide solution for 15 minutes, removing seeds and washing with water to passivate tomato mosaic virus; soaking with 1% copper sulfate solution After 5 minutes, remove and rinse with water to prevent anthrax and bacterial scab.

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.
