Methods of use of biopesticides for growing a good fruit crop

Methods of management of nematodes in the main field

Step 1: Soil application.

Land should be thoroughly ploughed, and soil should be brought to a fine tilth. Add recommended doses of fertilizers. Also add carbofuran or phorate @ 20 – 25 kg + 200g neem/ pongamia/ mahua cake per acre. Maintain optimum moisture in the beds for proper decomposition of neem/ pongamia/ mahua cake.
For organic farming, apply two tons of FYM or 500 kg of neem cake / pongamia cake or one ton of vermi-compost enriched with Pseudomonas fluorescens + Trichoderma harzianum + Paecilomyces lilacinus during the land preparation.

Process of Enrichment of FYM

  •  One ton of well decomposed FYM has to be enriched by mixing with 2 kg each of Pseudomonas fluorescens + Trichoderma harzianum + Paecilomyces lilacinus formulation under shade. It has to be covered with mulch, and optimum moisture of 25 – 30% has to be maintained for 15 days.
  • Once in a week thoroughly mix the FYM for maximum multiplication of and homogenous spread of the microorganisms in the entire lot of FYM.

Process of Enrichment of Neem cake

  •  1 ton of neem cake has to be enriched by mixing with 2 kg each of Pseudomonas fluorescens + Trichoderma harzianum + Paecilomyces lilacinus. It has to be covered with mulch, and optimum moisture of 25 – 30% has to be maintained for 15 days.
  • Once in a week thoroughly mix the neem cake for maximum multiplication & homogenous spread of the microorganisms in an entire lot of neem cake.

Process of Enrichment of vermicompost

  •  1 ton of vermicompost has to be enriched by mixing with 2 kg each of Pseudomonas fluorescens + Trichoderma harzianum + Paecilomyces lilacinus. It has to be covered with mulch, and optimum moisture of 25 – 30% has to be maintained for 15 days.
  • Once in a week thoroughly mix the vermicompost for maximum multiplication and homogenous spread of the microorganisms in an entire lot of vermicompost.

 

Step 2: Application of biopesticides at the time of planting:

Apply bio-pesticide enriched FYM@ three kg or enriched neem cake @ 250g or enriched vermicompost @500g/plant at planting and an interval of six months.

 

Step 3: Spraying:

The IIHR patented organic formulation containing Pseudomonas fluorescens & Trichoderma harzianum has to be sprayed on the plants at regular intervals of 30 days at a dosage of 5g/ lit or 5ml/ lit.

 

Step 4: Drenching or application through drip irrigation system:

The IIHR patented organic formulation has to be given through drip/ by drenching @ 5g/ lit or 5ml/ lit. At the regular interval of 30 days.

  •  By following all these methods, farmers can get 15 – 20% increase in the yield of the crops.
