Online published on 27 November, 2018. Abstract Many nematode species have been reported from black pepper plants but root-knot nematodes (Meloidogyne spp.) are known to cause serious damage to the crop. Hence with the aim of managing this soil borne pathogen two experiments were conducted in farmers field located at Thovalapadi of Idukki district Kerala, for two consecutive years 2014–2015 and 2015–2016. The experiments consisted of six treatments including untreated check viz; T1-carbosulfan 6% G @16.7kg/ha, T2-cartap hydrochloride 4%G @25kg/ha, T3-quinolphos 2ml/l @5l/Plant, T4-thiamethoxam 25% WG @100g/ha, T5-flubendiamide 20% WG @125g/ha, and untreated control. Maximum reduction in nematode population was recorded by plants applied with carbosulfan 6% G @16.7kg/ha. This was followed by the application of cartap hydrochloride 4%G @25kg/ha. Carbosulfan 6% G@16.7kg/ha was the most effective treatment in increasing the yield of black pepper for both the years. Cartap hydrochloride 4%G @ 25kg/ha was the next best treatment in increasing the yield. Carbosulfan 6% G @16.7kg/ha was statistically superior treatment in reducing the number of galls/5g roots. This was at par with cartap hydrochloride 4%G@25kg/ha. Top Keywords Meloidogyne incognita, nematode management, nematicides, carbosulfan, cartap hydrochloride, and thiamethoxam. Top |
