Abstract/ Executive Summary:

A study was conducted in the farmers ber orchard at Ishurdi, Pabna during rabi 2009-10 to develop a suitable management approach against nut weevil attacking ber. Results revealed that clean cultivation and collection and destruction of infested premature fruits from the trees and soil along with spraying of carbaryl 85 WP at flowering stage and cypermethrin 10EC at fruit initiation stage appeared to be the best management option offering the highest fruit infestation reduction over control(80.40%) and the highest yield (64.30 kg/tree).

Keywords: Ber, nut weevil, sanitation

Location: Pabna

Start Date: 10-10-2009

End Date: 20-03-2010

Program Area: Pest Management

Commodity: Jujube

Objectives:

To develop effective and economic management approach(es) for nut weevil in ber.

Methodology:

The experiment was conducted in the farmer’s orchard at Dhulti, Ishurdi, Pabna in Apple kul variety during rabi 2009-10. The treatments used in this experiment were as follows: T₁ = Clean cultivation + collection and destruction of infested premature fruits from the trees and the soil, T₂ = T₁ + two sprays of neem seed extract @ 50 g/L of water , 1st at initiation of flowering and 2nd at initiation of fruiting, T₃ = T₁ + two sprays of Carbaryl 85 WP @ 2 g/ L of water, 1st at initiation of flowering and 2nd at initiation of fruiting, T₄ = T₁ + two sprays of Cypermethrin 10EC @ 1 ml/ L of water, 1st at initiation of flowering and 2nd at initiation of fruiting, T₅ = T₁ + two sprays, 1st spray with Carbaryl 85 WP @ 2 g/ L of water at initiation of flowering and 2nd with Cypermethrin 10EC @ 1 ml/ L of water at initiation of fruiting and T₆ = Untreated control. The experiment was laid out in randomized complete block design (RCBD) with three replications. Single tree was considered as an experimental unit. The treatments were randomly allotted in each replication. Sprays were applied on the flowering canopy and trunks where adults were observed to take rest. Sprays were done with a high volume foot pump sprayer first at initiation of flowering and second at initiation of fruiting.
