Integrated Management of Mustard sawfly
Canada is the world’s largest producer of mustard in the world. In India, Uttar Pradesh rank in first for the production of mustard followed by Rajasthan. Madhya Pradesh, Haryana, Punjab, Gujarat and Maharashtra. Utmost cares should be taken for the mustard sawfly as this pest attacking at the early stage of the crop. While slight touching to this larva, it behave like dead and fall down on the soil (feign death). The larvae feed on the leaves by making circular shot hole at the crop stage of the 15 to 20 days. More than one larvae are seen on the lower surface of the leaf. In higher infestation, larvae defoliate all the leaves from the small plants and circumstances may be arise for the re-sowing.
Integrated Management: • Hand picking of the larvae at the initiation and destroy them in the kerosinized water. • When the population of larvae found of about 2 per sq. feet, spray neem oil 50 ml or neem based formulation 20 (1% EC) to 40 (0.15% EC) ml per 10 liter of water. • For taking the advantages of biopesticides, spray Bouveria bassiana @ 40 g per 10 liter of water. • In spite of these spray, if the population is not under controlled, spray quinalphos 25 EC 20 ml or imidacloprid 70 WG 3 g per 10 liter of water. • One can also use the dust formulation like quinalphos 1.5% or chlorpyriphos 2% @ 20-25 kg per hectare. It is not desirable to use such dust formulations looking to their adverse effect on natural enemies and environment. Dr. T. M. Bharpoda, Ex. Professor of Entomology, B. A.
