Abstract/ Executive Summary:

A field experiment was conducted during the kharif season of the year 2005-2006 and was located at chandaicona, Sherpur, Bogra to observe the effect of different synthetic pesticides on the control of borboti (yard long bean) fly and on the yield of borboti. There were five treatments: control, cruiser (thiamethoxam 70% seed treatment), Aktara (foliar spraying), Aktara (soil mixing) and Diazinon 60-EC. Borboti bean fly was significantly controlled by these sorts of synthetic pesticides, where the control showed the highest infestation at the early stage of plants and gave a lower yield. The Aktara (soil mixing) showed lower plant infestation and gave the highest yield. According to the producer company the synthetic pesticide Aktara has a minimal affect on human body and its using system is less hazardous to the environment and to the beneficial insects.

Keywords: Borboti bean fly, Synthetic pesticides, Yield of borboti

Location: Chandaicona, Sherpur, Bogra.

Start Date: 00-00-2005

End Date: 00-00-2006

Program Area: Pest Management

Commodity: Bean

Objectives:

Objectives of this study were to see the effect of different synthetic pesticides on to control the borboti bean fly; to find out the technology which is less hazardous to the environment and also beneficial insects; and to see the effect of different synthetic pesticides on the yield of borboti.

Methodology:

The trial was conducted during the year 2005-2006. Trial area was selected in the farmer’s field of MCC Partnership in Agricultural Research and Extension (PARE) program partner organization. The field was located at Chandaicona, Sherpur, Bogra. Only one farmer’s field was selected and the experiment was laid out with five treatments and each treatment contained 5 replications. The total land size was 258.125m² (17.5mX14.5m). The land was prepared during the first week of June, 2005 and it was ploughed four times with the power tiller. Finally the total plot was divided into 25 subplots and the size was 6.3m² (2.8m X 2.25m). Compost and chemical fertilizer like 1/3 of urea, TSP and MP was mixed during final land preparation. Rest 2/3 Urea was kept to use it as extra dose in the cropping period. For fertilizer application MCC recommended dose like compost, urea, TSP, MP @ 80 kg, 350g, 350g, 350g per decimal respectively. The compost was applied to the field before one week of chemical fertilizer application. Between two plots 70cm gap was maintained, where the gap between hills was 30cm and between plot to plot it was 70cm. Before seed sowing the synthetic pesticide Cruiser was mixed with seeds (5g/kg seed) for one treatment. Aktara as a soil mixing chemical was applied to the field (@ 10g/decimal). Before apply it was mixed with dry sand to make a large volume for easy application. First Aktara was mixed with soil in line than seeds were sown in hill on that line. Before seed sowing its germination rate was tested where, it showed 97.5% germination. Line sowing was followed and for each hill four seeds were sown, about 95% germination was ensured at the fifth day of seed sowing and finally two plants were kept removing after two. At 16 days of seed sowing the field completed with staking for well climbing of the plants. There were two treatments related with spraying for the control of borboti bean fly like Aktara (spraying) and Diazion 60-EC. The spray was two times per week. The spraying was started at its four to five leave stages and was continued up to three weeks. During the spraying the highest caution was maintained that it can’t go to the nearer field. The farmer was involved with all the activities from first to last. Some supportive activities including intercultural operations were done by the farmer during the trial period. Total trial cost was carried out by MCC, only the farmer gave his land to use it for research purpose. On the other hand he got all the productions; he sold the production to the market and got a good profit. The experiment laid out following the factorial design. There were five treatments and each treatment had five replications. Treatments were as follows – T₁=Control, T₂=Cruiser (Thiamethoxam 70% seed treatment), T₃=Aktara (foliar spraying), T₄=Aktara (Soil mixing or basal dose) and T₅=Diazinon 60EC

Achievement/Findings:

Borboti bean fly was successfully managed by the synthetic pesticide Aktara as a soil mixing chemical. Where as, another pesticide like cruiser as a seed treating pesticides and Aktara as a foliar spraying pesticides also did better. But our objective emphasized on to reduce the environment pollution. From that point of view Aktara as a soil mixing chemical is somewhat right to save the environment because it is not polluting air, not hampering the life style of beneficial insects and this pesticide can do a minimal affect on the human body. Aktara as a soil mixing synthetic pesticide doing better for third time and farmers feedback is also positive. So it can say that it may be an extendable technology for the farmers to control the borboti fly.
