Abstract/ Executive Summary:

This study evaluated the efficacy of nine botanicals against cotton jassid on cotton variety CB 12. The nine botanical treatments were neem leaf extract @ 100 ml L^-1 of water, turmeric powder @ 20 g L^-1 of water, coriander powder @ 20 g L ^-1 of water, black pepper powder @ 20 g L ^-1 of water, chili powder @ 20 g L ^-1 of water, Garlic extract @ 100 g of grated and crushed garlic cloves per L of water, eucalyptus oil @ 5 ml L -1 of water, mahogany oil @ 5 ml L -1 of water, neem oil @ 5 ml L -1 of water. The botanicals were applied four times at 7 days interval during the cotton growing season. Among the tested botanicals neem leaf extract with 100 ml L ^-1 water and chili powder 20 g L ^-1 water after 24, 48 and 72 hours of application exerted the lowest jassid population. The botanical treatments have insignificant effect on the population of beneficials. The neem leaf extract with 100 ml L^-1 water and neem oil with 5 ml L -1 water had greater effect on cotton jassid and revealed significantly lower levels of leaf infestation by number. Plots treated with neem leaf extract with 100 ml L ^-1water and chili powder with 20 gL water resulted in significantly higher yield than that of the control.

Program Area: Variety and Species

Commodity: Cotton

Objectives:

To determine the Use of Botanicals as Environmentally Safe Management for Cotton Jassid.

Methodology:

The experiment was carried out in the experimental field of the Department of Entomology of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur-1706, from July 2014 to April 2015. The experiment was laid out in a randomized complete block design (RCBD) with three replications. In experimental site total land area was 30.5m x 18m including the border. The land was divided into 30 equal plots (4m x 2.5m) with plot to plot distance of 0.5 m and block to block distance is 2.0 m. The whole area of the experimental field was divided into three blocks and each block was again divided into 10 unit plots. The row to row and plant to plant spacing was maintained at 80 cm x 40 cm respectively. Seeds of Cotton variety CB-12 were collected from Central Cotton Research, Training and Seed Multiplication Farm, Sreepur, Gazipur, Bangladesh. The seeds of cotton were sown directly in the main field on 10 July, 2014. The intensive care and all necessary intercultural operations including irrigation, weeding, thinning etc. were done in proper time to obtain healthy plants. The seed germinated within 3-7 days. The field was irrigated lightly immediately after sowing. Necessary intercultural operations were done throughout the cropping season to obtain proper growth and development of the plants. Treatments Nine botanicals were used in this experiment such as young Neem leaf extract @ 100 ml L ^-1 of water, Turmeric powder @ 20 g L ^-1 of water, Coriander powder @ 20 g L ^-1 of water, Black pepper powder @ 20 g L ^-1 of water, Chili powder @ 20 g L ^-1 of water, Garlic extract @ 100 g of grated and crushed garlic cloves per L of water, Eucalyptus oil @ 5 ml L ^-1 of water, Mahogany oil @ 5 ml L ^-1 of water, Neem oil @ 5 ml L ^-1 of water. Spraying was started from the advent of infestation and it continued at 7 days interval up to optimum harvesting. Preparation and application of treatments Mature black pepper, chili, turmeric and coriander were dried in an oven at 650 for 48 h to a constant weight, ground in a commercial grinding machine, and sieved to pass through a No. 18 (1 mm) mesh screen. Then 20 g dried powder of each material mixed with 100 mL of distilled water with 10 drops of 2% sodium dioctyl sulfo-succinate. The mixture was passed through a double-layer of cheesecloth and squeezed manually. The mixtures were then vacuum filtered using funnels. Young fresh leaves of neem Azadirachta indica were plucked from their parent plants. 100 grams of grated neem leaves were blended with 1 liters of water and 50 ml of soap (potash based soft soap that was used for washing dishes) and was mixed well. The mixture was passed through a fine cloth and squeezed manually. The solution was diluted in 5 liters of water. 100 grams of grated and crushed garlic cloves were blended with 1 liters of water and 100 grams of soap (potash based soft soap that was used for washing dishes) and mixed well, the mixture was strained through a fine cloth. The solution was diluted in 5 liters of water. Mahogany oil, Neem oil and Eucalyptus oil were collected from the producer from Shatkhira and Rajshahi and Chapainawabgonj, respectively. The nine botanicals insecticides were sprayed five times at 7 days’ interval in which four botanicals powder, three botanicals oils and two botanicals extracts. Spraying was started from the advent of infestation at 28 October 2014 and continued to 27 November 2014. During the spraying of botanicals oil the spraying doses were mixed with Tween 20 which acts as surfactant @ 0.01%. The spray mixture poured into the knapsack sprayer and sprayed covering the whole plants. The spraying was done during in the morning to avoid bright sunlight and drift caused by strong wind and adverse effect on pollinating insects. Statistical analysis The recorded data were compiled and tabulated for statistical analysis. Analysis of variance was done with the help of computer package STATISTIX 10 program. The mean differences of the treatments were observed by Least Significant Difference (LSD) test at 5% level of probability for the interpretation of results.

Achievement/Findings:

In this study nine botanicals were used to control cotton jassid. As synthetic insecticides are harmful for environment, so botanicals were used as ecofriendly management practices. Botanicals were sprayed at 7 days intervals. Effect of botanicals on the population of jassids, predator and yield of cotton were evaluated. The mean population of jassid was found lowest in neem leaf extract with 100 ml L ^-1 water followed by chilli powder @ 20 g L ^-1 water after 24 and 48 hours of spraying when applied of 7 days’ interval. But after 72 hours of spraying the mean population of jassid was the lowest in chilli powder treated plot followed by neem leaf extract treated plot. Botanical treatments have an insignificant effect on the population of beneficial insects. The highest yield was found in neem leaf extract @ 100 ml L ^-1 water followed by chilli powder @ 20 g L^-1 water treated plot when applied of 7 days’ interval. Garlic extract @ 100 g L ^-1water and neem oil @ 5 ml L^-1 water treated plots also gave a good result. The results obtained from the application of black pepper powder, coriander powder, turmeric powder, eucalyptus oil, mahogany oil were also satisfactory and better than that of the control.
