Field Efficacy of Certain Microbial Insecticides against &lt;I&gt;Plutella xylostella&lt;/I&gt; Linnaeus and &lt;I&gt;Pieris brassicae&lt;/I&gt; Linnaeus under Cabbage-Crop-Ecosystem of Manipur

Cabbage is considered as one of the most commonly found vegetables and it has been cultivated in large areas throughout the year. As it is mostly grown in large areas, higher rate of pest infestation likely to occur, which hinder its total production and consumption. However, continuous use of synthetic pesticides in agricultural pest management often leads to various negative impacts such as development of resistance by the pest, adverse effect on non-target organisms and hazardous effect on environment. These drawbacks led to an alternative approaches for control of crucifer pests that are cost effective, biodegradable, low toxic effect on non-target organisms and eco-friendly. This review brings together all the information of different biological practices for management of crucifer pests and list of botanical insecticides and entomopathogenic organisms that are being reported. This will help in establishing the knowledge of limited studies on pest management using different biological control methods to more challenging research and conveys the importance of pest management system for taking research forward.

“…Significantly higher curd yield of cauliflower was recorded in Cypermethrin than other treatments, as Cypermethrin was statistically similar to Spinosad. Aphids can cause damage on crop and significantly reduce the yield (Cartea et al 2009 Singh (2015). Significant effectiveness of the Spinosad was also supported by Wanner et al (2000) and Watson and Salgado (2001).…”

Cabbage butterfly (Pieris brassicae nepalensis) is an important pest of cabbage, cauliflower, and many other crucifers. Pesticide use is a popular method of pest management in small and large-scale vegetable farming in Nepal. These practices are directly linked to human health, biodiversity, and the environment. There are various categories of pesticides available in market, some are toxic, and some are ‘soft’ in nature. Chemical action of pesticides to the insect pest has been recommended by efficacy testing. Accordingly this research was done to evaluate the effectiveness of ‘soft’ chemicals against cabbage butterfly management. Cauliflower cultivar ‘Snow Mystique’ was used for the field experiment established at Agriculture and Forestry University (AFU), Rampur Chitwan during November 2017 to March 2018. Six common pesticides such as Mahashakti (Bt. based), Neemix (Azadirachtin based), Spinosad (bacteria based), Liquid manure (mixture of botanical, cow urine and other ingredients), Superkiller-10 (Cypermethrin based), and control (no use) were used in Randomized Complete Block Design (RCBD), each with four replication. The study findings revealed that the highest number of larval populations of cabbage butterfly as well as damaged plants, leaves, curds, and holes were recorded in control plot, and the lowest larval population and damages were recorded in Cypermethrin and Spinosad treated plots. On the other hand, curd height was significantly higher (13.9 cm) in liquid manure treated plot that was similar with Spinosad treated plots. There was no significant difference in curd diameter (23.1 cm) and biological yield (79.6 t/ha) in Spinosad and Cypermethrin treated plots. It is thus suggested that biological pesticide, such as Spinosad are superior in controlling pests of cauliflower than other tested pesticides. These pesticides along with other soft pesticide are potentially safer for vegetable production. This information is important to develop IPM protocol for cabbage butterfly management in crucifers.
