Product Description

2 Billion CFU/G Paecilomyces Lilacinus

Paecilomyces lilacinus, also known as Purpura lilacinus, belongs to the endoparasitic fungi, Sordariomycetes, hypocreales, serpentaceae (Ophiocordycipitaceae), purpureocillium. It is an important natural enemy of many plant parasitic nematodes. Mainly parasitic on eggs, it can also infect larvae and females, which can significantly alleviate the harm of nematodes such as root knot nematodes, cystic nematodes and stem nematodes of various crops. It has a certain control effect on insects such as bugs, termites, rice planthoppers, etc., and can also be used to prevent root rot, blight, etc., in addition, there is a certain role in promoting growth and degrading pesticide residues, which can be used as biological fertilizers, biological pesticides, biocontrol preparations and functional bacteria of bio-organic fertilizers.

I  Mechanism of action of Paecilomyces lilacinus:
Paecilomyces lilacinus kills nematodes by fungal phagocytosis and insecticidal active substances. On the one hand, after contact between the spores or mycelium of the nematode and the sporangia or eggs of the nematodes, the spores germinate, the apex of the hyphae thickens, the formation of infection nails and secretion of chitinase and protease, the decomposition of chitina and proteins in the egg shell or nematode body wall, and then, under the mechanical pressure of the infection nail, the infection nail invades the nematode egg shell or body wall. After the hyphae enter or the body of the nematode egg, the nematode or egg is used as a source of nutrition, thus killing the nematode. On the other hand, the hyphae secrete an acetic acid that is toxic to nematodes, directly killing the nematodes.
The insecticidal mechanism of Paecilomyces lilacinus has not been reported and should be much the same as that of nematode. The antagonistic activity against other plant pathogens comes from peptide derivatives, which can play a role similar to antibiotics.

II  Function characteristics of Paecilomyces lilacinus

1. Highly invasive

The infection rate of Paecilomyces lilacinus on nematodes such as root knot nematodes and sporangia nematodes can reach more than 90%, and the infection rate of larvae and adults is about 75%.

1. Egg killing and larvae are more effective

Paecilomyces lilacinus has a better effect on the eggs and larvae of the target nematodes than adults, and better on females than male adults, but has a lower rate of infection on egg cysts that have been conceived and formed.

1. The action time is long, and the effect is slow

After the application of Paecilomyces lilacinus into the soil, the infection rate reached the highest after 14 days, and the contrast effect was significant after 3 months.

1. No resistance is generated

Paecilomyces lilacinus is the natural enemy fungus of target nematodes, and the infection rate of eggs and females with eggs in the body is high, which can accelerate the hatching of nematode eggs, infect and kill larvae, and block the inheritance of dominant genes. Therefore, resistance is not easy to develop.

1. Continuous use works better

Paecilomyces lilacinus can be colonized in the rhizosphere or root of crops, generally within the first week of sterilization, the types of root microorganisms are significantly reduced, fungi, bacteria and actinomycetes are reduced by 16%, 27% and 37% respectively, and after 4 weeks, Paecilomyces lilacinus tends to be balanced in the original fungi in the soil. Therefore, it can be applied every other month, maintaining the dominance of the bacterium.

1. Green and safe

This product is a fungal biocanidal nematicide, which has no oral toxicity to humans and animals.

III Objects of prevention and control
Paecilomyces lilacinus is effective against a variety of nematodes such as root-knot nematodes, cystic nematodes, golden nematodes, heterodermal nematodes, perforated nematodes, stem nematodes, and even roundworms in humans and animals. Can be widely used in tomatoes, melons, cucumbers, strawberries, ginger, tobacco, bananas, grapes, dragon fruit, chrysanthemums, sanchi, luo han guo, melon, a variety of vegetables, melon fruits, flowers, Chinese herbal medicine root knot nematode control.
Paecilomyces lilacinus can parasitize lychee bugs of the order Hemiptera, rice black bugs; Homoptera, leafhoppers, brown planthoppers; Isoptera termites; Coleoptera sweet potato weevil worms and lepidoptera tea silkworms, lamp moths, etc.
Paecilomyces lilacinus has obvious antagonistic effects on maize small spot disease, wheat gibberellosis, cucumber anthrax fungus, cotton wilt, curly leaf virus disease, rice evil seedling disease, striated blight, sunflower and natto root cancer.
Paecilomyces lilacinus has a certain function of degrading pesticide residues, and can also promote the transformation of insoluble phosphorus in soil. However, due to the high production cost of this bacterium, it is mainly used for nematode control.

IV The application method of 2 billion cfu/g Paecilomyces lilacinus SP

1. Seed dressing method: before sowing, mix the bacteria with the seeds, pile them up for 2 to 3 hours, and sow seeds after the shade is dried.
2. Seedbed treatment: before re-seedlings, spread the bacteria evenly on the seedbed; Or after sowing, the fungus is made into a turbid liquid and evenly watered the seedbed.
3. Sprinkling method: Before rotary tillage and land preparation, mix this product with organic fertilizer or chemical fertilizer and other bottom fertilizers, and evenly spread and then apply to the ground.
4. Hole casting: Before colonization, mix the bacteria proportionally with fine soil or rotten organic fertilizer and evenly sprinkle them in the colonization hole or cultivation ditch.
5. Root irrigation method: for the water solvent type, it can be made into a suspension, which is applied for the first time when watering the slow seedling water after colonization, and the dosage is half of the amount used for the whole stubble; After that, it is used every other month or so, and the application is stopped 30 to 45 days before the seedling pulling, and the dosage is half of the amount used in the whole stubble divided by the number of follow-up applications.
6. Soil burial method: The diseased strain can be plucked from the soil layer around the root neck, and the bacteria are mixed with fine soil to be buried around the opened root neck. Then water it through.
7. Mixing substrate: The bacterium can be mixed evenly with the seedling substrate or cultivation substrate, and directly sown or cultivated.
8. Comprehensive application: ditch application or cave application before colonization, the dosage is half of the amount of stubble; After colonization, it can be applied or irrigated, applied for the first time 45 days after colonization, and then used every other month, and stopped applying 45 days before pulling seedlings, and the amount used is half of the amount of stubble divided by the number of follow-up applications.
9. The specific amount of use is determined according to the number of active live bacteria of the selected product.

V. Precautions

1. Take care to use safely
Paecilomyces lilacinusenters the eye, easy to cause keratitis, if accidentally into the eye, please rinse immediately with a large amount of water.
 

1. Use when appropriate

For plots where the anterior stubble is present, it is important to use the fungus before stubble colonization. For plots where nematode damage has occurred after colonization, the root should be irrigated with the fungus in time.
 

1. Environmental conditions

The PH value of Paecilomyces lilacinus can be grown from 2 to 12, and the optimal pH value for the growth of the fungus is 5 to 6, and the growth is slow on the alkaline medium. This bacterium can grow normally at 8 °C ~ 38 °C, the fastest growth under the condition of 25 °C ~ 30 °C, and the largest spore production; Humidity is crucial for spore germination, with spores starting to germinate at 85% of the RH, 98% RH, and the highest rate of spore germination at 25°C. Therefore, after the application of bacteria, it is necessary to maintain soil moisture, which can effectively improve the effect.
 

1. Mixture of fungi

Paecilomyces lilacinus and actinomycetes can be mixed to double synergistics. It can also be mixed with bacterial preparations such as Bacillus subtilis to learn from each other's strengths and expand the scope of insect treatment, but do not mix with fungi with strong antagonistic fungal ability (such as Trichoderma harzibosus) to reduce the effect.
 

1. Mix fungal fertilizer

The soil is rich in organic matter, which is conducive to the growth and reproduction of fungi agents, so it can be mixed with Paecilomyces lilacinus and organic fertilizer; Nitrogen fertilizer has a synergistic effect on the bacterium; At the same time as the application of the fungus, some sucrose was applied, and the effect was significantly better. Copper and magnesium ions have a significant inhibitory effect on the bacteria, and the application of the bacteria should avoid mixing with fertilizers containing copper and magnesium
 

1. Mix of fungi and drugs

The bacterium has a certain pesticide compatibility, according to research, only a few copper preparations have a significant inhibitory effect on the bacteria, and insecticides have basically no effect on the bacteria. Therefore, for the plots with serious root knot nematodes, Paecilomyces lilacinus can be mixed with avermectin and thiazolidinate, which can exert the chemical pesticide insecticidal fast and the biopesticide efficacy for a long time, so as to achieve the effect of complementary advantages.
 

1. Storage

The fungal agent product likes to be cool and afraid of heat, and humidity can easily lead to early germination of spores, so it should be stored in a cool and dry place to avoid moisture failure. During the summer heat, be sure to refrigerate the refrigerator.
