1. The success story of Nematode management in poly house

Poly house-grown vegetables (cucumber) in the Thanniyam area of the Anthikad block of Thrissur district, Kerala was heavily infected with  Meloidogyne incognita. The poly house in these areas was dominated by soil having a high proportion of sand. The farmers were recommended to make furrows measuring 60cm breadth and 30cm depth and filling it with red soil exported from nematode free area. Beds were made and the beds are covered with polythene mulches of 30-40-µ thickness. The seeds are sown as in these beds. Application of 20g of Trichoderma enriched F Y M @20g was also recommended per plant. The plants established well with less than 10 galls per plant and there was also a reduction in population to a tune of 20 J2/200cc soil in the root zone area. There was a huge increase in the yield of crops like cucumber. The same technology was transferred to other farmers of the area growing Amaranth and chillies and they also succeeded in reducing the nematode damage in their poly houses also.

2. Salad cucumber grown in Polyhouse at Kattachalkuzhy was severely affected by root-knot nematode. The crop was completely failed due to root-knot nematode fungal disease complex.  The nematode population in soil was  650-720 M. incognita juveniles per 200cc soil. Recommended soil solarization and application of partially decomposed farmyard manure enriched with Paecilomyces lilacinus . In the next crop, the population was reduced to 180 nematodes per 200cc soil. The longevity of the crop also extended. Vellayani 2016-17 2016 8

Management of Rice root-knot nematode meloidegyne graminicola in South and South Western Haryana Rice root-knot nematode, Meloidogyne graminicola, which is a serious pest of rice and can also sustain on the wheat crop during the rabi season, has been spreading in non-traditional rice-growing areas of the state. These areas include the south and southwestern Haryana. Although the farmers are being made aware through different extension activities e.g. Farm Darshan, KisanMela, DhanMela, GianDiwas, Radio & TV talks, Field Days, Agricultural Technology Information Centre (ATIC), etc. yet the nematode is being recorded even in newer areas. In this regard farmers, who had been facing the problem of this nematode for the last 5-6 years, were selected at four different locations, for the study.  Paddy yields reduced drastically year after year due to the invasion of the nematode, despite the fact that they applied almost all the recommended agronomic practices.

After ascertaining that the sudden decline in the paddy yield was due to nematode attack, they tried to fight the menace by applying chemicals/nematicide (carbofuran @ 1.5-2 kg a.i./ha) for three consecutive years. They got partial success and were able to make up the yield losses only to some extent. However, the soils being very light in texture were heaven for the growth and multiplication of the nematode. Repeated persuasion and convincing for rotating the rice with non-host or poor host crops, two farmers replaced paddy with cotton in village Badopal (Fatehabad) and third replaced paddy with sorghum in village Badesara (Bhiwani). Two of the farmers harvested 26 and 30 quintal seed cotton (Kapas) each per hectare area and the third farmer harvested very good yield of sorghum as fodder. The fourth farmer did not replace paddy with any such crop and yields of paddy went on declining due to attack of the nematode. Even the farmers of surrounding areas are undoubtedly convinced with the replacement idea of the crop and endorsed the crop rotation formula adopted by the affected farmers to tackle the problem of rice root-knot nematode in paddy.

4. Soil solarization, a non-chemical method to raise root-knot nematode free seedlings of various transplanted crops in the nursery is developed by the center. This technology is adopted by the farmers to raise seedlings of tobacco, tomato, chili, and brinjal. AAU, Anand 2001 1995 Nursery growing farmers

Root-knot nematode (Meloidogyne indica) infecting acid lime (Kagzi) cultivation in Gujarat:

Complains were received from the citrus growers of Deesa and Kherva villages of Banaskantha and Mehsana districts respectively that 5-7 years old citrus orchards are drying slowly and within a few years, whole orchard is totally vanished. Then scientists from AICRP on Nematodes and Department of Nematology visited such orchards and found severe root galling due to root-knot nematode infection. Later on, Meloidogyne indica, a species of Meloidogyne that is not found in Gujarat was identified. To restrict further spread in other areas and to create awareness among framers about this nematode problem, we organized farmer’s day at KVK, Ganpat University, Kherva. More than 600 farmers and nursery men attended this meeting. In this gathering, scientists gave information on various aspects to raise nematode free citrus seedlings, nursery and field management.
