TRIFONOVA, Z. and A. ATANASOV, 2011. Control of potato cyst nematode Globodera rostochiensis with some plant extracts and neem products. Bulg. J. Agric. Sci., 17: 623-627
An experiment was conducted under glass-house conditions to test the effects of five plants products in the form of drenches on the growth of potato and population density of potato cyst nematode Globodera rostochiensis. All the tested formulations improved plant growth, yield and suppressed the nematode multiplication. Neem oil+extract of Nicotiana tabacum 0.5% or Veratrum album 1.0% were the most effective in reducing the disease incidence (77.7 – 77.8%), followed by neem Azal 0.3% (66.6%) and neem oil 0.3% (50.0%). None of the formu-lations was phytotoxic even at the tested concentration.
