Abstract/ Executive Summary:

The study was conducted to know the diverse response on growth stages of mustard varieties to mustard aphids. Among ten mustard varieties, the maximum aphid population was recorded on Tori-7 at flowering stage but the population reached to the peak in BS-5 variety. Pod formation stage was more vulnerable for aphid infestation and increased population. Aphid infestation received higher at pod formation stage than flowering stage and consequently produced lower yield. Moreover, experiment indicated that aphid infestation were severe in 2007 as compared to 2006 in respect of percent infestation and number of aphids per plant under study.

Keywords: Mustard aphid, Mustard variety, Growth stage, Infestation, Lipaphis erysimi

Location: Rampur, near the Patuakhali Science and Technology University

Start Date: 00-00-2006

End Date: 00-00-2007

Program Area: Pest Management

Commodity: Mustard

Objectives:

To know the diverse response on growth stages of mustard varieties to mustard aphids.

Methodology:

The experiment was conducted at the village Rampur, near the Patuakhali Science and Technology University, on different plots during crop season of 2006 and 2007. The experiment was done at filed observation under the natural condition. All plots receiving ten varieties of mustard viz. Nap-3, Shambol, Safal, Agrani, YS-52, Sampad, SS-75, Sangam, BS-5 and Tori-7 were exposed to aphids for infestation. Irrigation was done by the use of river water. Sowing was done in the first week of November, 2006. The plants were kept in an optimum number for well maintaining in each plot by reduction the excess plants. Number of mustard aphid (Lipaphis erysimi) was recorded randomly selected plant in each plot from the start of infestation. Data were recorded weekly from early February till the end of March. The whole plant height in each plot was selected for experiment and number of aphids was recorded gently with the help of stick. Dislodged aphids were collected on a piece of white paper and then counted. The experiment was laid out in a Randomized Complete Block Design (RCBD) having four replications with ten varieties of mustard. The data were analyzed by RCBD using ANOVA by treating varieties in each plot and mean separation was done by DMRT at 0.05 probability level.

Achievement/Findings:

From the research findings, it can be concluded that southern belt of Bangladesh, specially Patuakhali, Barguna were apt cropping area for mustard cultivation by using some specific varieties of Mustard. Among ten varieties of mustard, Nap-3 and Shambol were the most tolerant varieties against the severe aphid infestation in that area whereas Tori-7 and BS-5 were not suitable for that area because of highly susceptibility to aphids.
