A living soil is the basis of organic farming. A live healthy soil with proper cropping patterns, crop residue management and effective crop rotation can sustain optimum productivity over the years without any loss of fertility. Organic farming is the holistic production management system that avoids use of synthetic fertilizers and pesticides, minimizes pollution of air, soil and water and optimizes the health and productivity of independent communities of life, plants and animals and people. It envisages a comprehensive management approach to improve soil health, ecosystem of the region and quality of the produce. Advantages of organic farming: Helps in maintaining environment health by reducing the level of pollution. Reduces human and animals hazards by decreasing the level of residues in the product. Ensures optimum utilization of natural resources for short term benefits and helps in conserving them for future generation. Makes agriculture sustainable. Improves the physical and chemical properties of soil. Helps in conserving natural resources for future generation. Biozin-PTB is a talc based biopesticide containing three aggressive strains of antagonists, viz., Pseudomonas aeruginosa ( 1 x 109 cfu/g), Trichoderma harzianum ( 2 x 109 spore/g) and Bacillus brevis ( 1 x 109 cfu/g) with standard adhesive and osmoticant. It has ability to biologically control rhizome rot and wilt of ginger and turmeric; wilt disease of Tomato, Brinjal, Chilli, Capsicum; Damping off, Foot rot, Root rot and wilt of Peeper, Betelvine, Cabbage, Peeper, French bean, different Gourds etc. The benefits of Biozin-PTB: It is safe to health and environment as there is no residual or environmental hazards; It is being plant-growth-promoting, beneficial to the plant, soil and environment; The delivery system is very easy and does not need sophisticated equipments; It improves soil health as it has the ability to convert unavailable phosphatic nutrients; It enhances the growth and yield abilities of the crop plant, imparts ‘induced systemic resistance’ in crop besides controlling harmful pathogens; It is economic compared to application of commercial chemicals and antibiotics. Application Methods: 1.Ginger/ Turmeric/ Potato : Seed/ rhizome treatment: Treat seeds/ rhizomone in 5 % (5 Kg in 100 lit. of water) . ‘Biozin’ for 1 hr. before sowing. With 100 lit. of aqua-solution 10q seeds/ rhizome can be treated. Soil application: Apply ‘Biozin’ @ 2% to the soil before sowing. Mix 2 Kg ‘Biozin’ with 1q dry cowdung / Vermicompost, incubate for 7 days in cool place, cover with a Hessian cloth and sprinkle water daily if required. For 1 bigha land 2q of such mixture (15q/ha) is required. After 60-90 days of sowing, 100g of this mixture can be further applied at the base of the plant. Spray application: For management of rhizome rot of ginger 3 spray application of ‘Biozin’ @ 5% (5Kg/100 lit) at 60, 90 and 120 days of sowing is further recommended. The soil near the base of the plant should be thoroughly drenched during spraying. 100 lit of ‘Biozin’ sprays suspension is required/ bigha. 2.Tomato, Brinjal, Chilli etc : Seed treatment: Treat the seeds with 10% ‘Biozin’ paste (100g in 1 lit water/ rice gruel/ Revive, for 12 hr. dry under shade before sowing. Seedling / root treatment : Treat the roots of seedlings with 10 % ‘Biozin’ paste, for 1 hr. under shade before transplanting. For 1000 seedlings 1 Kg ‘Biozin’ paste (2.5 Kg/ bigha) is required.
