Symptoms of gray mold:
Gray mold is an important disease in greenhouse cultivation. It can occur on petioles, leaves, buds, flowers, fruit stalks, and fruits. The most serious disease is on fruits. When the disease occurs on the leaves, brown water-soaked lesions appear. When the humidity is high, white downy hyphae appear on the back of the leaves. The petioles and fruit stalks turn brown after being infected, and the lesions often surround the petioles and fruit stalks, and finally wilt and dry up. When the fruit becomes infected, small oil-stained light brown spots appear, and then the spots expand, the whole fruit becomes soft, and gray mold grows on it.
The incidence of gray mold:
The pathogenic fungus of gray mold mainly overwinters or oversummers in diseased leaf dead plants as mycelium, and is spread through wind, rain, agricultural operations, etc. Suitable temperature and high humidity are necessary conditions for the disease, especially high humidity, which is the main factor for the occurrence and development of the disease. Botrytis gray mold is prone to occur under environmental conditions of -℃ and high humidity. If the protected area encounters continuous rainy weather and is not ventilated in time, the disease will seriously occur when the humidity increases. In addition, excessive plant density, dense foliage and poor management can promote the occurrence and development of diseases.
Botrytis biological control technology
Micro-composite Trichoderma
There are different ways of using it according to different crop types and crop periods. The main thing is to make Trichoderma evenly distributed on the roots and surface of the plants. In the soil, it can be used once for short-term crops and three times a year for perennial crops such as fruit trees and flowers. The more times Trichoderma is used, the more obvious the effect. Long-term use can effectively reduce the occurrence of soil-borne diseases. Multiple uses are beneficial and harmless. When using Trichoderma, rice bran or soybean meal is often added to increase the energy of Trichoderma proliferation in the field and facilitate the dispersion of Trichoderma in the field. The amount used is about twice that of Trichoderma.
[Scope of application]
Effectively targets soil-borne diseases such as root rot, damping-off, damping-off, and fusarium wilt of crop plants, flowers, and fruit trees, Botrytis cinerea, Pythium, Rhizoctonia, Anthrax, Fusarium, Sclerotinia.
[Product Overview]
Micro-Trichoderma Compound
is a new type of biological pesticide. By producing antibiotics, nutrient competition, microparasitism, cell wall decomposing enzymes, and inducing plant resistance, it has antagonistic effects on a variety of plant pathogenic bacteria. Trichoderma compound has dual protective and therapeutic effects and can effectively prevent and control soil-borne fungal diseases. , using Trichoderma agent in the seedbed can improve the survival rate of seedlings and transplants, and maintain the healthy growth of the seedlings. It can also be used to prevent and control gray mold. It has a long effective period, multiple action sites, does not produce resistance to antibiotics, breaks through the limitations of conventional fungicides, and is not afraid of high humidity. The greater the humidity, the better the control effect. It has a broad bactericidal spectrum, no residual toxicity, and no adverse effects on crops.

[Mechanism of action]
Antagonism:
Trichoderma produces small molecule antibiotics and large molecule antibacterial proteins or cell wall degradation Enzymes inhibit the growth, reproduction and infection of pathogenic bacteria. In its antibiotic and bacterial parasitism, Trichoderma can produce chitinase, b,
glucanase, cellulase and protease to decompose the cell wall of plant pathogenic fungi or secrete extracellular enzymes such as glucosidase to degrade it. Antibiotic toxins produced by pathogenic bacteria. At the same time, Trichoderma also secretes antibacterial proteins or lytic enzymes to inhibit the infection of plant pathogenic fungi.
Competitive effect:
Trichoderma can seize water and nutrients, occupy space, consume oxygen, etc. through rapid growth and reproduction, and even weaken and eliminate gray mold pathogens in the same habitat.
Reparasitism:
Research has found that Trichoderma will form Pythium in a specific environment and has a reparasitism effect on Botrytis cinerea. It forms a large number of branches and sexual structures after entering the host hyphae. Therefore, it can inhibit the appearance of grape gray mold symptoms.
Induced resistance:
Trichoderma can induce host plants to produce defense responses, which not only directly inhibits the growth and reproduction of Botrytis cinerea, but also induces crops to produce self-defense systems to acquire disease resistance.
Growth-promoting effect:
Research has shown that during use, Trichoderma can not only control the occurrence of gray mold, but also increase the germination rate of seeds, the length of roots and seedlings, and the vitality of plants. .
[Product Efficacy]
Prevention and Control of Soil-borne Diseases:
Trichoderma strains screened for soil-borne diseases are fermented and produced with natural substrates. It destroys and decomposes pathogenic bacteria in a super-parasitic and anti-biotic manner, while promoting plant root growth. It is suitable to be mixed with organic fertilizer and used after multiplication. It can also be used from the seedling stage, and the effect is more significant.
Wide range of use:
Trichoderma has antagonistic effects on a variety of plant pathogenic fungi and has a wide range of control. It has strong saprophytic properties and can be used as a multi-purpose medicine to reduce the cost of prevention and control. It can produce various antibiotics and lytic enzymes while being parasitic, reducing the resistance of pathogens and enhancing the antibacterial strength. The chitinase gene of Trichoderma can be used in bacteria, fungi and plants. Expression can prevent and cure plant fungal diseases and promote crop growth.
