Product Description

Pseudomonas fluorscens introduction

Brief introduction:
Pseudomonas fluorescens is a type of Gram negative rod-shaped bacteria that can generally produce water-soluble fluorescent pigments in KingsB culture medium. Fluorescent Pseudomonas aeruginosa has a broad-spectrum antibacterial effect. The fluorescent Pseudomonas aeruginosa agent processed through advanced fermentation technology has good root growth promoting effects, can prevent and suppress the occurrence of soil borne diseases such as ginger blast and bacterial wilt in eggplants, tomatoes, chili peppers, and tobacco, and has the characteristics of promoting seed germination, improving germination potential, and seedling emergence rate. It is an efficient and non-toxic agent Environmentally friendly microbial formulations that are pollution-free and pollution-free.

Character: Earth yellow to yellowish brown powder, insoluble in water
Main type of formulation:
100 billion cfu/g WP, 300 billion cfu/g WP, 600 billion cfu/g TC
Mechanism of action:
1.Nutritional parasitism
Pseudomonas fluorescens can reduce the incidence of mushroom brown spot disease from 100% to 76% -11.1%, which Nair and Fahy believe is related to nutritional competition; On the plate, fluorescent bacteria have no inhibitory effect on pathogenic bacteria, only competition for nutrients; Later research results suggested that the growth of pathogens was mainly influenced by competition for iron ions.
2.Site competition
As a biocontrol bacterium, Pseudomonas fluorescens can first colonize the rhizosphere or root surface of plants, and then act on the produced iron or antibiotics, which has been confirmed by many research works. The colonization of bacteria at the root protects the infection sites of pathogenic bacteria, reduces infection opportunities, and is a key factor in disease prevention.
3.Bacteriostatic effect
There are two types of oxidized phenylpyrrole antibiotics produced by Pseudomonas fluorescens: one is Pyroluteorin, which can prevent cotton seedling rot fungus from collapsing, but has no effect on Fusarium wilt; Another type is Pyrrolnitin, which is only effective against Rhizoctonia, but not against Pythium wilt disease.

1. Bacteriolysis

There are few reports and insufficient evidence, but the possibility cannot be denied.

Methond of application:
 

Pseudomonas fluorscens 100 billion cfu/g WP use dosage
Crop/Site	Controlled	Dosage(formulation/ha.)	Application method
Rice	Rice blast	750-1050g/ha.	Spraying
Cucumber	Gray mold disease	1050-1200g/ha.	Spraying
Cucumber	Target leaf spot	1050-1200g/ha.	Spraying
Totacco	bacterial wilt	8400-9900g/ha.(300billion cfu/g)	Irrigation root

Technical requirements for use:

1. Cucumber gray mold and target spot disease are suitable for the first application before or at the initial stage of the disease, with an interval of 7 days, a total of 2-3 times of application, and the whole plant spray; The control of rice blast shall be conducted before the break of rice, before the onset of rice blast or at the initial stage of rice blast, with an interval of 7-10 days. The whole plant shall be spray twice.
2. The frequency of spraying can be increased or decreased according to the local disease occurrence pattern, and the use can be reduced by half when preventing diseases.

3. The application of pesticides should be carried out in the morning and evening when the temperature is low and the wind speed is low. It is not suitable to apply pesticides during high temperature periods and before and after rainfall.

Matters needing attention:
1. Avoid mixing with strong alkalis and acidic substances, and can be mixed with the vast majority of pesticides. Before mixing, it is recommended to conduct small-scale experiments first, and the pesticide should be applied as soon as possible after mixing with water; 2. It is recommended to rotate the use of fungicides with different mechanisms of action to delay the development of resistance; 3. When using this product, one should wear a mask, protective clothing, glasses, and gloves to avoid inhaling medication; 4. During the application period, food and water should not be consumed, and the entire body should be cleaned in a timely manner after application; 5. Keep away from aquaculture areas for pesticide application, and it is prohibited to clean the pesticide application equipment in rivers, ponds, and other water bodies to avoid contamination of water sources by the pesticide solution; 6. Used containers should be properly disposed of and should not be used for other purposes or discarded at will; 7. Avoid contact with pregnant and lactating women.

First aid measures for poisoning:
If accidentally touching the skin or splashing into the eyes, rinse with plenty of water for at least 15 minutes. If you still feel unwell or accidentally take it, immediately bring this label to the hospital for symptomatic treatment

Storage and transportation methods:
This product should be stored in a dry, cool, ventilated, and rainproof place, avoiding sunlight and rain, and away from ignition or heat sources. Keep out of reach of children, unrelated personnel, and animals, and lock them. Do not store or transport with other commodities such as food, beverages, grains, feed, etc.

Shelf life:2 years


Pseudomonas fluorescens is a type of Gram negative rod-shaped bacteria that can generally produce water-soluble fluorescent pigments in KingsB culture medium. Since the 1970s, a large number of Pseudomonas fluorescens have been isolated to resist plant disease. Widely distributed around the world, it can produce a variety of antibiotics, which have antagonism effect on important plant disease such as wheat full bell disease and cotton lodging disease, and play a role in natural biological control. Both pot and field experiments have shown that soaking seeds or spraying leaves with these bacteria can protect crops from disease invasion.

There are 8 species of Pseudomonas fluorescens, among which Pseudomonas chrysanthemum and Pseudomonas yellow-green are plant pathogenic bacteria, Pseudomonas aeruginosa is opportunistic human pathogenic bacteria, occasionally causing chrysanthemum decay, and the other 4 species are saprophytic, namely Pseudomonas fluorescens, Pseudomonas aeruginosa, Pseudomonas auruginosa, and Pseudomonas fetida. These species can produce diffuse fluorescent pigments, but the main ones related to disease prevention and control are Pseudomonas fluorescens and Pseudomonas putida.
