Abstract/ Executive Summary:

An experiment was conducted at Sher-e-Bangla Agricultural University farm to study the efficacy of some insecticides against major insect pests of French bean (Phaseolus vulgaris L.). The treatments of the experiment were T₁: Bamper 20SL (Imidacloprid) @ 0.5 ml L^-1, T₂: Shobicron4 25EC @ 2 ml L^-1, T₃: Actara 25WG (Thiamethoxam) @ 0.3 g L^-1, T₄: Chlorpyriphos 20EC @ 3 ml L^-1, T₅: Sinothrin 10EC (Cypermethrin) 1 ml L^-1, T₆: Fortap 50SP (Cartap) @ 3 g L^-1 and T₇: Control treatment. Results showed that the lowest number of whitefly plant^-1 (3.28 at 60 DAS) and aphid plant^-1 (4.82 at 60 DAS), the lowest infestation intensity by whitefly (5.92%) and aphid (14.25%), the lowest infested bean yield plant^-1 (52.80 at 60 DAS), highest healthy bean yield plant^-1 (166.40 g at 60 DAS), highest total healthy yield (11.28 t ha^-1), lowest total infested yield (0.64 t ha^-1) and highest gross return (Tk. 232000.00 ha^-1) were obtained from the use of Chlorpyriphos. The highest percent reduction of whitefly plant^-1(81.44 % at 60 DAS) and aphid plant^-1 (80.15 % at 60 DAS), highest percent reduction of infested bean yield plant^-1 (81.82 % at 60 DAS) and highest increase of healthy bean yield plant^-1 over control (215.20 % at 60 DAS) were achieved from the same treatment. Hence Chlorpyriphos 20EC performed best to suppress the whitefly and aphid of French bean followed by Fortap 50SP.

Objectives:

To study the efficacy of some insecticides against major insect pests of French bean (Phaseolus vulgaris L.).

Methodology:

The experiment was conducted at the experiment field under the Entomology Department of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period of January to March 2011. Treatments of the study were assigned as follows: T₁ = Bamper 20SL (Imidacloprid) @ 0.5 ml L^-1, T₂ = Shobicron 425EC @ 2 ml L^-1, T₃ = Actara 25WG (Thiamethoxam) @ 0.3 g L^-1, T₄ = Chlorpyriphos 20EC @ 3 ml L^-1, T₅ = Sinothrin 10EC (Cypermethrin) 1 ml L^-1, T₆ = Fortap 50SP (Cartap) @ 3 g L^-1 and T₇ = Untreated Control. Insecticides were procured from local market. The experiment was layout in a Randomized Complete Block Design (RCBD) with four replications in the field. The French bean seeds (BARI bush bean^-1) were collected from Pulse Research Centre, BARI, Joydebpur, Gazipur. The seeds were subjected to germination test before sowing. In all cases, the rate of germination was found to be more than 90%. Three seeds per pit were sown in each plot of the experimental field. Seeds of French bean were sown on 15 January 2011. Bamper, Shobicron, Actara, Chlorpyriphos, Sinothrin and Fortap were sprayed in assigned plots at 15, 35 and 55 days after germination of plant and dosages by using Knapsack sprayer. Spray materials were applied uniformly to obtain complete coverage of whole plants of the assigned plots. Caution was taken to avoid any drift of the spray mixture to the adjacent plots at the time of the spray application. At each spray application the spray mixture was freshly prepared. After five days of spray, data was collected on the following parameters, incidence of whitefly plant^-1 by number, incidence of aphid plant^-1 by number, weight of infested bean plant^-1, weight of healthy bean plant^-1, total healthy yield (t ha^-1), total infested yield (t ha^-1) and gross return (taka ha^-1). Infestation intensity was calculated. All data were analyzed by MSTAT-C software for analysis of variance (ANOVA). Treatment means were separated by applying Least Significant Difference (LSD) test.

Achievement/Findings:

Incidence of whitefly and bean aphid was lowest with application of Chlorpyriphos 20EC @ 3 ml L^-1. Highest total healthy fruit yield, lowest infested fruits and highest gross return were found from Chlorpyriphos application while control showed lowest performance. Thus, Chlorpyriphos 20EC @ 3 ml L^-1 could be recommended for chemical control of whitefly and aphid insect infesting French bean.
