The Pseudomonas fluorescens preparation is an environmentally friendly microbial preparation that is highly efficient, non-toxic, pollution-free, and non-polluting. It uses Pseudomonas fluorescens with broad-spectrum antibacterial activity, and is processed into a microbial low-toxic fungicide by advanced fermentation process. It has good root growth effect and can prevent and inhibit tomato, eggplant, pepper and tobacco. The occurrence of soil-borne diseases such as bacterial wilt and ginger blast in solanaceous crops can be used for various crops such as vegetables, cotton, wheat, rice, and tobacco.

Functional characteristics According to the principle of plant virus biological control, the microbial live pesticides protect the plants from pathogenic bacteria by inhibiting the bacterial competition and site occupation by the active ingredient Pseudomonas fluorescens, and effectively inhibit the pathogens. Growth, to achieve the purpose of disease prevention and treatment. In addition, Pseudomonas fluorescens can also produce auxin substances, promote the growth of crop roots, and solve the problem of rotten roots. It can effectively control the rotten seeds, dead seedlings and dry plants and white spikes caused by diseases in wheat, and has better control effect on wheat total etch disease, and cure root rot and sheath blight. It can also be used to control the bacterial wilt of plants such as tomatoes and tobacco, and can promote the germination of seedlings and promote the growth of plants with the dual functions of disease prevention and bacterial fertilizer. It also has certain effects on the control of cotton blight, cotton mites, tobacco black shank and rice sheath rot.
Method 1 is used to control wheat whole-waste seed dressing: firstly wetting the seeds, and then mixing the pesticide with 100 kg of seeds at a dose of 1.0 to 1.5 kg of 500-g/g wettable powder. Irrigation root: use 100~150g/500g/g wettable powder per acre, add 100~150kg of clear water, stir well, and irrigate the roots.
2 Prevention and control of tobacco bacterial wilt using 300 billion pieces per gram of powder 512.5~662.5 grams of soaking + pouring + root filling.
Precautions Avoid direct sunlight during the seed dressing process. When filling the roots, make the liquid as far as possible into the root zone, and mix with pesticides and fungicides. Store in a dark, dry place. The product should be sealed and packaged.
3 Control tomato bacterial wilt and roots with 100~100 times liquid of 100 million/ml water. China's pesticide network recommends 300 billion per gram of Pseudomonas fluorescens powder 437.5~550g soaking + pouring + root filling.
