Studies on Effectiveness of Nemahari Against Root Knot Nematode Disease Meloidogyne incognita of Mulberry to Reduction of Cocoon Yield Losses of Bivoltine Silkworm in Pune Region

The Nemahari is an ecofriendly a plant based formulation for management of ischolar_main knot disease and plant extracted products from Azadirachta species and utilize to soil application to prevent the ischolar_main knot nematode severe infection of mulberry and does not harm the beneficial microflora in soil which is more effective to inhibits the multiplication of nematode galls and Root-knot disease of mulberry is caused by the nematode Meloidogyne incognita. It has important economic implications for sericulture. and found its infection with counting more than 50 galls per plant in pune region, of Maharashtra and its noticed caused by 8-10 percentage is losses the foliage production of mulberry which is affects to quality and quantum in cocoon production per unit area. objectives are attempts to prevent the multiplication of nematode and reduction of galls per plant the botanical nematicide or biopesticide was prepared as nemahari even make a study16kg mix with 160 kg farm yard manure to apply this mixture in the trench along ischolar_main zone area of plant in the depth 15 cm and covered with the soil and repeated after 70-80 days, in field of mulberry (Morus sp L.) is effectively. The mulberry infected with Meloidogyne incognita juveniles (J2). Pretreatment (ending 6 days before inoculation) and post-treatment (starting 6 days after inoculation) schedules were tested. The two uninoculated control batches were treated with the same procedure with nemahari Both pre- and post-treatment significantly reduced nematode infection in terms of ischolar_main gall number and nematode population in ischolar_mains of mulberry. All the treated plants showed improved growth in terms of fresh biomass of shoot and ischolar_main, length of shoot and ischolar_main, num of leaves, leaf surface area, ischolar_main and leaf-protein content. is more effective in all respects of nematode control as well as growth of the test plants. Pretreatments show slightly better effects than the post-treatments. It is interesting that inoculated and treated plants not only are less affected by nematodes but also have a better growth than uninoculated, untreated control. This biopesticide is more useful measure in control of nematode infection of mulberry.
