Control potential of some indigenous biochars against meloidogyne incognita [(Kofoid and White) Chitwood] in tomato (Solanum lycopersicum L.)

The use of biochar has been shown to suppress populations of soil-borne pathogens. Hence it has been promoted as one of the eco-friendly alternatives to synthetic pesticides. In the current study, the effects of different sources of indigenous biochar on Meloidogyne incognita and overall growth and yield of tomato were evaluated under screenhouse condition in 2016 and 2017. A total of 10 treatments were evaluated in the...
