Cotton is a significant fiber crop filled in northern Ghana. Its development is plagued with various bug issues. Current irritation the executives rehearses in cotton fields depend on the utilization of chlorpyrifos and lamda cyhalothrin based manufactured insect poisons which is exorbitant to most laborer cotton ranchers. Consequently, this study pointed toward evaluating the field adequacy of neem based biopesticides like neem seed portion concentrate and neem seed oil as an option for the administration of bug vermin of cotton in northern Ghana. The medicines were 2% NSO, 5% NSO, 5% NSKE, 10% NSKE, chlorpyrifos exchanged with lamda cyhalothrin and untreated control. The outcomes showed that 10% NSKE altogether (P<0.05) diminished the wealth of bollworms, aphids and white flies to 0.75, 3.71 and 3.29 separately while for the untreated control they were all around as high as 3.07, 14.14 and 6.75 individually. The neem was non-poisonous to the regular adversaries. Seed cotton yield were somewhere in the range of 52.20% and 90.82% higher in the neem treated plots than the untreated control while yield misfortune was 64.79% lower on the 10% NSKE treated plots than the untreated control plots.
