Effect of varying levels of achichi (Cannabis sativum L.) seed oil extract in the inhibition of bacteria spot disease of scotch pepper (Capsicum annum L.)

Negative food safety reports over the use of synthetic pesticides in controlling bacteria disease of pepper caused by Xanthomonas campestris pv is increasing in Nigeria, hence the need for friendly options. An experiment was carried out at the Teaching and Research Farm of Rufus Giwa Polytechnic, Owo, located on latitude 70 12N and longitude 50 35E at 350m above sea levels, to evaluate the effect of varying levels of achichi (Cannabis sativum L.) seed oil extract in the inhibition of bacteria spot disease of scotch pepper (Capsicum annum L.). Treatments include; Positive control (Synthetic Rindomil gold), Negative control (distill water), 2 ml ASO (Achichi seed oil), and 4ml ASO (Achichi seed oil) which were randomly distributed into plots, arranged in a Randomized Complete Block Design (RCBD). Results showed that the application of ASO had bactericidal inhibition potential against the bacteria spot diseases comparable to the synthetic ridomil powder. Application of between 2 – 4 ml / 1 liter of water of ASO was found to significantly influence the general performance of sprayed pepper in the study area. Further investigation should be carried out to determine the right volume between the ranges of 2 ml – 4 ml of ASO that can effectively control the bacteria spot disease in the study area.
