Know Root-Knot Nematodes in Vegetables- Farmkey

Nematodes – especially root-knot nematodes – cause great damage in vegetable fields, greenhouses and vegetable crops in home gardens. Root-knot nematodes are a subtle roundworm that can break the roots of some plant species and can lay their eggs inside the roots.

Many spring-bearing vegetables such as beet, carrots, peas, potatoes, radish, and other vegetables are susceptible to root-knot nematodes. Nematodes are almost inactive at low temperatures and with increasing temperatures, their activity increases. If the temperature is above 30 ° C then it is suitable for nematodes.  Vegetables can be widespread damaged after planting in late spring and summer, other common vegetables grown during the mid-late summer, such as tomatoes, black pepper, cucumber, squash and eggplant.

Plants growing in nematode-infected soils are usually indistinguishable, rustic, yellowish, and are bile and decay. Plants with infected roots are more sensitive to other diseases due to fungal and bacteria and stop early production. Root-knot nematode problems can be detected by checking the roots of rooted knots and vegetables, through harvesting or soil assay.

The crop loss due to these nematodes can be greatly reduced by using the control method.

Crop Rotation

Crop cycle is one of the oldest and most economical methods of controlling nematodes

Resistant varieties

Many vegetable seeds and varieties are resistant to root-knot nematodes and will also produce a good crop in the presence of nematodes. Effectiveness increases when the crop cycle is resistant.

Biological Control-

Nematofree- Nematofree is a fungus which penetrates the body of the Nematodes and starts taking nutrition from the body of Nematodes. Apart from that this fungus also secrete few enzymes which are poisonous for the eggs of Nematode

Chemical Control

Bayer Velum prime – Bayer Velum prime has the active ingredient Fluopyram (Pyridinylethylbenzamide)  500 g/l. it effectively controls the Root Knot Nematodes, Lesion nematode and Spiral nematode. Its recommended does is 250 ml/Acre.  It has to be applied in soil using drenching method
