Pre-treat the suckers with 40 g carbofuran 3G for the control of root-knot, burrowing and lesion nematodes. If pre-treatment is not done, apply 40 g carbofuran around each plant one month after planting or pare and dip the corm into 0.75% Monocrotophos solution; shade dry and plant. Grow sunhemp after 45th day and incorporate one month later. Apply press mud @ 15 t per ha and neem cake 1.5 t per ha one month after planting.
Apply 60 g carbofuran 3G or 20 g phorate 10G per vine a week before pruning and irrigate the plots profusely for the control of root-knot nematode. The soil should not be disturbed for at least 15 days. Thereafter normal manuring may be done. Application of neem cake @ 200 g/vine also controls nematodes. Alternatively, apply Pseudomonas fluorescens @ 100 g per vine in talc formulation (15 x 108 cfu/g), 30 cm away from base of the vine at least 15 cm depth at the time of pruning.
Apply carbofuran 3G @ 1 g/polythene bag after germination at nursery stage for the control of root-knot nematode.
Apply carbofuran 3G at 10 g/m2 at sowing and 1 kg a.i./ha in the main field one week after transplanting. Treat the seeds with Trichoderma viride at 4 g/kg seed along with press mud at 5kg/m2 for nematode disease complex.
Apply neem cake @ 1 ton/ha at planting to control root knot nematode, Meloidogyne hapla.
- Avoid growing potato year after year in the same field. Follow rotation of crop with vegetables (radish, garlic, cruciferous crops) and green manuring with lupin. Apply carbofuran 3G (1 kg a.i.) 33 kg/ha in furrows while seeding. For cyst nematode, grow resistant variety Kufri Swarna, using half the dose of the above nematicide.
- Seed treatment with Pseudomonas fluorescens @ 20 g/kg seed and its soil application @ 2.5 kg/ha for managing potato cyst nematode.
- Soil application of Pseudomonas fluorescens or Trichoderma viride @ 2.5 kg/ha at the time of sowing for managing cyst nematode, Heterodera cajani.
- Seed treatment with Pseudomonas fluorescens and Trichoderma viride @ 5+5 g/kg seed for the management of cyst nematode in pigeonpea.
Seed treatment with Pseudomonas fluorescens @ 20 g/kg and its soil application @ 2.5 kg/ha for managing reniform nematode.
Seed treatment with Pseudomonas fluorescens @ 20 g/kg followed by its soil application @2.5kg/ha for managing reniform nematode.
Application of carbofuran 3G @ 1 kg a.i./ha both in nursery and in main field at 45 days after planting for managing rice root-knot nematode, Meloidogyne graminicola.
Apply Purpureocillium lilacinum (cfu 2 x 106/g) as seed treatment @ 10 g/kg seed followed by its soil application @ 50 g/m2 for the management of root-knot nematode, M. incognita.
