What's fungicide ?

Plant disease is the main enemy of agricultural production. According to the Food and Agriculture Organization of the United Nations (FAO), the average annual loss of production due to plant diseases is 10% to 15%. At present, the main means of controlling plant diseases is chemical fungicides. However, due to potential human health hazards, environmental pollution, non-target organisms, and development of plant pathogen resistance, the development of chemical fungicide has been limited. Biological fungicide are attracting more and more people’s attention and interest. What’s Biofungicides? Bio-sourced fungicides refer to the direct use of biologically active substances produced by biological organisms or biological metabolic processes or substances extracted from organisms as a disease prevention and treatment. The concept of biological pesticides is vague and can be considered equivalent to biologically derived fungicides. According to s...

6 ways to stimulate plants root growth

图片
Root growth is vital for plants growth.It’s responsible for the absorption of nutrients and water, as well as controlling the physiological activities of the aboveground organs. 6 ways to stimulate plants root growth 1.Adjust the soil pH of the plough layer Unreasonable fertilization for many years leads to changes in the pH value of the plough layer, which is the root cause of today’s soil problems. Our recommendation is to use a special soil conditioner according to the actual situation after testing the pH of the plough layer. 2.Adding biological fertilizer(Such as  Trichoderma harzianum ) The application of biological fertilizer can improve the soil condition, they are suitable to be applied on soils problems with salinization,hardening and acidification.Significantly improve these soil condition and promote the growth of root system, and can control harmful bacteria and fungus or other organisms to r...

Bacillus subtilis grows fast.It can produce heat-resistant and stress-resistant spores. It can be made into various dosage forms. It can be mixed with chemical pesticides without inactivation, and the mass production process is simple, the cost is low, and the application is convenient and storage. bacillus subtilis The effects of Bacillus subtilis on plants are mainly reflected in the following aspects: 1.Nutrition and space competition The competitive effects of Bacillus subtilis mainly include nutritional competition and spatial locus competition. It can rapidly and massively multiply and colonize in the rhizosphere, body surface or in the soil and in the soil, effectively reject, prevent and interfere with the colonization and infection of plant pathogenic microorganisms on plants, thereby achieving antibacterial and disease-preventing effects. 2.Produce antibacterial substances Bacillus subtilis can produce a variety of substances with antibacteria...
