Most of the microbes use phytotoxic chemicals as carbon and energy source and hence degrade them.
Example:Trichoderma viride controls Rhizoctonia solani causing black scurf disease of potato
Higher dose of inoculum ensure maximum and better association of nitrogen fixing bacteria with rhizosphare leads to more nitrogen fixation.
Answer: To get long term control of insect pest with less cost. It is an integrated approach. Integrated Crop Management (ICM) is a pragmatic approach to crop production. ICM is based on understanding the intricate balance between the environment and agriculture, and is a whole-farm approach in achieving a proper balance. Its basic components are crop management, nutrient management, pest management and ultimately financial management. One of the main objectives of ICM is reduction of external farm inputs, such as inorganic fertilizers, pesticides and fuel by means of farm produced substitutes. ICM assumes a broad palette of available disease and pest control methods, such as biological, cultural and physical controls, host plant resistance, and decision support tools.
Trichoderma viride is a natural bio-fungicide, highly effective in controlling wide range of soil borne crops disease caused by Fusarium, Rhizoctonia, Pythium, Schlerotinia, Verticillium, Alternaria, phytopthora, anjd other fungus.
Bio-products have the potential to provide larger and more sustainable yields and healthier soils. The cost of bio-products is less than chemical products due to use of renewable and low-cost substrate.
The performance of plants is directly related to the degree of the fertility of soil. Plants require 16 essential elements to grow well and to remain healthy. The 16 elements are categorized as Major Nutrients: Nitrogen (N), Phosphorus (P), and Potassium (K) Secondary Nutrients: Calcium (Ca), Magnesium (Mg), and Sulfur (S)
Micronutrients: Boron (B), Chlorine (CI), Copper (Cu), Iron (Fe), Manganese (Mn), Molybdenum (Mo), and Zinc (Zn). The Bio-products like biofertilizer, solubilizing and mobilizing organism provides these all element to plant either by direct fixation or by solubilization and mobilization of soil available elements.
Any person engaged in the business of import or manufacture of any insecticide shall make an application to the Registration Committee within a period of seventeen months from the date of such commencement for the registration of any insecticide which he has been importing or manufacturing before that date.
Answer: Several chemical fertilizers have high acid content. They have the ability to burn the skin. Changes soil fertility. They grow plants but do nothing to sustain the soil.
On the Other hand Bio-products adds natural nutrients to soil, increases soil organic matter, improves soil structure and tilth, improves water holding capacity, reduces soil crusting problems, reduces erosion from wind and water, Slow and consistent release of nutrients, and better control of plant diseases.
Answer: In evening hours when there is sufficient moisture in the soil. Different methods are available for applications of various biofertilizers which are outlined below:
1. As seed inoculant-e.g., Rhizobium. Seed treatment is a most common method adopted for all types of inoculant. The seed treatment is effective and economic.
2. As soil inoculant-e.g., carrier based blue-green algae, Azotobacter.
3. As seed & soil inoculant – VAM fungi.
4. Carrier materials for BGA inoculum are straw, rice bran, polyurethane foam and sugarcane waste.
When Biofertilizers inoculation are use for three to four consecutive cropping seasons, the inoculate microbes establish well and the effect persisted over subsequent crop.
Answer: Yes, as long as the crop variety and biofertilizer strain are optimally matched, and environmental conditions are favorable for the microbe and plant. In crops like most of the vegetable 100% biofertilizer gives result equivalent to chemical fertilizer, but it should be done gradual replacement. In most of the crops it has found that biofertilizer work better if mix with chemical fertilizer because they complement each other.
There is no need to mix T. viride with FYM for seed treatment and seedling treatment, but if applied for soil drenching and horticulture crop then mix with FYM desirable.
Answer: No side effect.
Chemical fertilizers may have a temporary, salutary effect on a crop in terms of yield but they also have a long-term destructive effect on the environment supporting the crop. In addition to soil erosion, chemicals can pollute the watershed. This, in turn, will harm livestock, wildlife and public health. Biofertilizers leave no such legacy. In fact, the opposite is true: they strengthen the soil profile, leave water sources untainted and edify plant growth without detrimental side-effects.
Answer: Disease control very successfully & very fast Insect control process is slow but sure.
Mixing of chemical inputs with bio pesticide can inhibit mycelial growth, colony population and spore germination.
