Abstract/ Executive Summary:

Effects of cyperin 10 EC and neem extract on pollinators, fruit setting and fruit quality of mango was investigated. Number of pollinators visited mango inflorescence was higher in morning in comparison to noon and afternoon. In control plants, average 25.67 pollinators visited within 30 minutes which was higher than cyperin 10 EC (20.00) and neem extract treated (24.34) plants. The pollinators were under the order Hymenoptera (26.31%), Diptera (52.42%), Odonata (5.26%) and unidentified (10.53%). Bloomed and fertilized flowers were lower in cyperin treated plants than neem treated and control plants. Highest average fruit weight was obtained from neem treated plants, whereas cyperin treated plants gave lowest percentage of infested fruit and control plants gave highest percentage of deformed fruit.

Location: BAU, Mymensingh

End Date: 00-06-2011

Program Area: Pest Management

Commodity: Mango

Objectives:

To identify the effects of Cyperin 10 EC and Neem extract on pollinator abundance, fruit setting and quality of mango

Methodology:

The study was carried out at the Germ Plasm Centre of Bangladesh Agricultural University, Mymensingh during the period from December, 2010 to June, 2011. Nine mango plants of Amrapali variety of 10 years old was selected. Of them three plants were randomly selected for each two treatments (Cyperin 10 EC 0.1%, Neem extract 10%) and a control using distilled water. Each treatment was sprayed three times. The first spraying was done before flower initiation, second on emergence of inflorescence but before flowering and the final spraying on after fruit setting. For pollinators movement, one flowering branch of each tree was observed for 30 minutes. Hand counter was used to count the number of pollinators. The data were recorded at morning (9.00-9.30 h), noon (14.000-14.30 h) and afternoon (16-16.30 h) for consecutive seven days. During peak blooming season, 5 sweepings/netting/tree were done from all nine trees in three random days and captured pollinators were identified in the laboratory. Pollinators captured per netting counted and expressed as percentage. One inflorescence was randomly selected from each of the plant and the number of bloomed flowers were recorded by using a magnifying glass during first fortnight of March. After fertilization of flowers, the fertilized flowers were counted and the number of fertilized flowers indicates the fruit set of the inflorescence. Finally, fruits of one branch were harvested, counted and weighted. Average fruit weight was calculated by dividing the total wt. of fruit by the number of fruits. Data were recorded for nine plants separately.Statistical Packages for Social Science (SPSS) was used to analyze the data. F-test were performed to see the significant difference among treatments and DMRT for multiple comparison.

Achievement/Findings:

Neem extract was found positive interaction with flowering, fruiting and in insect pest control. Considering the availability and low cost of neem, it could be suggested to minimize pest infestation, increase fruit production and thereby saving pollinators from insecticidal hazards.Highest average fruit weight was obtained from neem treated plants, whereas cyperin treated plants gave lowest percentage of infested fruit and control plants gave highest percentage of deformed fruit.
