Biological Pesticides
The company is at present manufacturing and marketing the following talc based biological pesticides products:
Boom Derma is an eco friendly biological fungicide containing conidial spores and mycelial fragments of the selective strain of antagonistic fungus Trichoderma viride. It controls diseases like damping off, wilt, collar rot, root rot, leaf blights spots in various economically important crops. It also produces toxic metabolites like gliotoxin, viridin and trichodermin which reduce the population of pathogenic fungi.
Composition
| CFU Count | 2 x 106 cells/gm minimum |
| Biomass | 1.50 % |
| Talc powder | 97.00 % |
| Carboxy methyl cellulose | 1.50 % |
Mode of Action
Hyphae of Trichoderma viride grow tropically towards pathogenic fungi, coil around them in a lectin-mediated reaction and degrade the cell walls of the target fungi by producing cell wall-degrading enzymes and bore holes to extract nutrients for their own growth. This process limits the growth and activity of the plant pathogenic fungi.
Method of application and dosage
- Seed Treatment: Mix 5 gm of Boom Derma in 50 ml of water and applied on 1 kg of seed uniformly. Shade dry the seeds for 20 – 30 minutes before sowing.

Biofertilizers
Biofertilizers are defined as preparations containing living and efficient strains of microorganisms that help the plants to uptake the nutrients by their interactions in the rhizosphere when applied through seed or soil. They accelerate certain microbial processes in the soil which augment the extent of availability of nutrients in a form easily assimilated by plants.
Very often microorganisms are not as efficient in natural surroundings as one would expect them to be and therefore artificially multiplied cultures of efficient selected microorganisms play a vital role in accelerating the microbial processes in soil.
Use of Biofertilizers is one of the important components of integrated nutrient management, as they are cost effective and renewable source of plant nutrients to supplement the chemical fertilizers for sustainable agriculture.
Our liquid biofertilizers manufactured by using Tangential Flow Filtration (TFF) Technology, contains unique preservatives that ensures longer shelf life, tolerance to adverse conditions and better survival on seeds/soil.
The company is at present manufacturing and marketing the following liquid formulation of biofertilizer products:
