Control of Tomato Root-Knot Nematodes 

Tomato crops often suffer from root-knot nematodes (Meloidogyne spp.), which damage roots, reduce plant growth, and lead to lower yields. A highly effective, eco-friendly method to manage this problem is using neem or karanja cake enriched with beneficial microbes like Trichoderma harzianum, Pseudomonas fluorescens, and Bacillus subtilis.

What to Apply

• Neem or Karanja Cake: 250–500 kg per acre

• Trichoderma harzianum: 2–3 kg per acre

• Pseudomonas fluorescens: 2–3 kg per acre

• Bacillus subtilis: 2–3 kg per acre

How It Works

• Neem and karanja cake release natural compounds that inhibit nematode eggs and larvae.

• Trichoderma parasitizes nematode eggs and harmful fungi in the soil.

• Pseudomonas fluorescens and Bacillus subtilis produce secondary metabolites that suppress nematodes and promote root health.

Application Method

1. Mix neem or karanja cake with Trichoderma, Pseudomonas, and Bacillus powders.

2. Apply uniformly to soil 10–15 days before transplanting.

3. Maintain adequate soil moisture to activate microbial growth.

Key Benefits

• Significant reduction in root gall formation

• Improved root development and plant vigour

• Enhanced flowering and fruit set

• Long-term improvement in soil microbial health
