Solution Control of nematode with special reference to pointed gourd
Country India
Last update: 25/12/2010
Summary Vegetable crops are frequently attacked by the nematodes causing huge economic loss to farmers and also inviting attack from other forms of pathogens. It is generally soil borne and hence can be avoided by following carefully chosen cultural practices. These include suitable cropping sequence, good nursery bed management, neem cake application as nutrient source, raising nematode traps like merry gold, colocasia, puin saak etc. However, if infestation is in the main field and in severe form then application of Carbofuran 3G at prescribed rate can be helpful.

Challenge/Issue Nematode attack to vegetables has become a common feature in many parts of West Bengal. It is mostly observed in the nursery beds and/or uplands where water does not stand generally. This is the situation where most of the vegetables are grown in this state. Many nematodes of vegetable crops attack the plant root, gall is formed in it, growth of plants retarded, leaves become chlorotic, flower and fruit form lately production is significantly reduced. It also increases the chance of fungal/bacterial/viral attack. In developing countries 14.6% crop loss has been recorded due to nematode infestation. In India, this figure stands 12% for vegetable crops.
Method 1. Follow crop rotation. Do not go for similar crops in single piece of land (potato, brinjal, tomato, chilli; pumpkin, pointed gourd, bitter gourd; cabbage, cauliflower etc. are generally considered to be of similar nature).
2. Do not continue pointed gourd for more than 2 years on the same land.
3. Try 1-2 ploughing during the summer.
4. Cover the nursery bed with polythene sheet for 6-8 weeks before sowing/planting.
5. Apply Carbofuran 3G in the nursery bed @ 10g/m2.
6. Treat the vine/root with systemic nematicide.
7. Apply neem cake in the main field @ 15-20 kg/bigha*.
8. Apply Carofuran 3g @ 4 kg/bigha in the main field. Try to apply 1 teaspoon of Carbofuran near the base of the plant.
* 7.5 bigha = 1 hectare
Lessons learned 1. Growing vegetables in the same land allows continuation of the nematode generations. Keeping pointed gourd for more than two years, hence, enhance the chance of nematode attack. At least once paddy can be grown in that land to break this continuation of nematode generations.
2. Cultural practices are more important in nematode control than chemical control alone. It should strictly be started from the nursery bed itself.
3. Chemical should be applied near the base of the plant followed by irrigation/application of water. It will help in dissolving the chemical.
