Abstract

Leafhopper (Empoasca kraemeri) is one of the key pests of cowpea. Along with the growing use of chemical pesticide, several research works had been done to examine their efficacy to reduce the key pests of cowpea. Not only emphasizing the chemical pesticide, this paper has checked and compared the efficacy of chemical pesticides with bio-pesticides against leafhopper. For the experiment, treatment namely Jholmol (125ml/L), Neem (Azadiracta indica) extract (2ml/L) and Cannabis extract (100g/L) as bio-pesticides, Chloropyrifos 50% EC and Cypermethrin 5% EC (2 ml/L) as chemical pesticide along with control was assigned and the research was conducted in the horticulture research field of Agriculture and Forestry University, Chitwan, Nepal in 2018. The experiment was laid out in Randomized Block Design (RBD) with five treatments i.e. four insecticidal treatments and one untreated control in four replications. The results showed that all the insecticidal treatment was found significantly efficient over the control. From the three insecticidal application, it was found that chemical pesticide showed highest control on leafhopper which is at par with Neem extract, followed by Cannabis extract and Jholmol. But yield of cowpea was found significantly highest in Neemix application (100.7qt/hac) at par with chemical pesticide (93.75qt/ha) amongst the insecticidal treatment, while lowest in control (68.6qt/hac). Similarly, the highest net profit and lowest incremental cost/benefit ratio was obtained in Neem extract treatment followed by chemical pesticide, Jholmol and Cannabis extract. It showed that the use of bio-pesticide like Neem extract can replace the chemical pesticides providing better yield and efficiency.
