Abstract/ Executive Summary:

The effect of net barrier and some synthetic pesticides on red pumpkin beetle and on yield of cucumber was investigated using farmer’s field at one location, Madhupur, Tangail during the year 2005-2006. The treatments were control, mosquito net barrier, carbofuran (soil mixing pesticide) and foliar spraying of Diazinon-60EC. There were differences in case of overall performance of the treatments and in some cases it was more or less similar. However, in control there was a highest leaf and fruit infestation by the red pumpkin beetle but yield was very near to the highest yield performance because in net barrier plants were free from infestation but a month after removed of net barrier plants showed more susceptibility to the red pumpkin beetle and other insects also. The carbofuran performed well compared to other treatments.

Keywords: Synthetic pesticides, Net barrier, Yield

Location: Madhupur, Tangail

Start Date: 00-00-2005

End Date: 00-00-2006

Program Area: Pest Management

Commodity: Cucumber

Objectives:

Objective of this study was to see the effectiveness of net barrier to control the red pumpkin beetles at its seedling stage and finally at the production stage; to find an environment-friendly technology which is less hazardous to the environment and friendly to the beneficial insects; and to see the effect of different synthetic pesticides on the yield of cucumber.

Methodology:

The study was conducted at farmer’s field of Jalchatra, Madhupur, Tangail under the jurisdiction of a partner organization, Jalchatra Mission from May to August, 2005. The treatments were laid out in RCB design with 5 replications. Treatments were as follows – T₁= Control, T₂= Mosquito net barrier, T₃= Use of Carbofuran (soil mixing pesticide) and T₄= Foliar spraying of Diazinon 60-EC. Land was prepared by four ploughing and was leveled properly. Recommended doses of compost, 40kg/decimal and chemical fertilizers like urea: 460g, TSP: 460g and MP: 230g per decimal were mixed during final land preparation followed by MCC crop calendar (2003). The area of unit plot was 2mX 8m = 16m², where the total land was 64m² in size. The main plot was divided into 20 subplots. Three seeds were sown in each hill and hills were arranged in rows, where 1.5 m distance was kept between plant to plant and row to row. A drainage canal of 25cm between two rows was kept. The mosquito net barrier was set just after seed sowing and it was funnel like to look at. At 30 days after sowing (DAS) the net barrier was removed. In each hill finally one plant was kept and uprooting the other two and at this time shoots and root length data were recorded. In the treatment Carbofuran (as a soil mixing chemical)- the pesticide was mixed with hill soil just before seed sowing. At 30 days, thinning of plants was done and keeping one per hill and at that time root and shoot length data were recorded. In the treatment using Diazinon 60EC as a folier spray, it was sprayed to the field and it was starting from the first week after emergence and it was continued once per week till harvest. Necessary intercultural operations were done properly. Farmer was related with all kinds of trial activities. They were not so interested to do that and that is why the research assistant had to spend a lot time for this purpose. 50 cm high bamboo sticks were posted around the hill and pesticides were sprayed to the field in every 8, 15 and 21 days. Data was recorded at different stages during the cropping period. At each harvest, the number and weight of both infested and healthy fruits were recorded and the presence of fruit infestation was calculated. The cumulative plot yield of healthy and infested fruits was converted to yield per hectare. Fruit infestation was calculated using the following formula: Fruit infestation by number (%) = Number of infested fruits/Number of total fruits X 100.

Achievement/Findings:

Though there is a dramatic growth rate was occurred in the treatment net barrier but at the final stage yield was not at satisfactory level. Obviously it is true that plants remain free of infestation when it is in the net barrier, but a month after removed of net barrier, the plants showed more susceptibility to the red pumpkin beetle and other insects also. It may be that due to open condition plants of other treatments built a resistance against different natural threats and finally they gave an acceptable yield, but growth and yield was drastically reduced in the treatment net barrier. After removing the net barrier environment friendly materials like some botanicals had to be used to save the plants.
