Abstract/ Executive Summary:

An experiment on the control of spiraling white fly (Aleurodicus dispersus Russel) by spraying detergent (wheel powder, Liver Brothers Ltd.) was conducted. Wheel powder, a cheap and readily available detergent in Bangladesh was sprayed to control the white fly. Wheel powder was sprayed in different concentration among which 10 g litre^-1of water and 15 g litre^-1of water were found more effective in controlling white fly. The concentration 20, 30 and 40 g litre^-1 of water were found serious leaf burning, even total leaf dropping after 3^rd spray.

Start Date: 00-10-2000

End Date: 00-01-2001

Program Area: Pest Management

Commodity: Insects

Objectives:

To control the spiraling white fly of guava by spraying wheel powder, a common, cheap and readily available detergent of Bangladesh.

Methodology:

The experiment was conducted in the Guava Orchard of Germplasm Centre of Fruit Tree Improvement Project, Department of Horticulture, Bangladesh Agricultural University, Mymensingh during October-January 2000 and 2001. Different levels of concentrations, viz., 1.0, 2.5, 5.0, 7.5, 10.0, 15.0, 20.0, 30.0 and 40.0 g litre^-1 detergent (wheel powder) were mixed with tube well water and were sprayed 3, 10 and 20 days after the 1^st spray. The total population of the insect was counted before 1^st spray, 3 days after 1^stspray but before 2^nd spray, 10 days after 10 1^st spray but before 3^rdspray and 21 days after 1^st spray but before 4^th spray as 2^nd, 3^rd and 4^th spray was done 3, 10 and 21 days after 1^stspray respectively. Knapsack sprayer was used to spray the detergent. It was sprayed during 10-12 am. The two-factors experiment was laid out in randomized complete block design (RCBD) with 4 replications having 3-unit plant per replication.

Achievement/Findings:

In conclusion, the cheap and readily available detergent, wheel powder was found most effective to control white fly. Spraying of the wheel powder @ 10 g litre^-1 of water at 4th spray (21 after 1^st spray) was found most effective to control the white fly without any burning of the guava leaves. The 2^nd spray was done 3 days after the 1^stspray, 3^rd spray was done 10 days after the 1^st spray and the 4^th spray was done 21 days after the 1^stspray. Spray of the detergent @ 15 g litre^-1of water was also found most effective if it was sprayed two times with out any leaf burning.
