Although the overall mango production is likely to be good in the northern region, the production in Rajshahi and Chapainawabganj districts may be hampered by unfavourable weather this year. The farmers in the two districts are concerned as a large number of green mangoes have been torn from the trees by the recent nor’westers and hailstorms. The unfavourable weather follows the earlier attack by leaf hoppers which had caused many green mangoes to fall before ripening properly. Farmers told the news agency that the dropping of green mangoes would reduce production, particularly in the two districts. Dr Alim Uddin, principal scientific officer of Fruit Research Station, agreed that the production of mangoes would be slightly less than expected, but not considerably because mango trees remain unaffected by bad weather in many other parts of the region. “Mango production will not be satisfactory in my area this year as almost 70 percent of the fruits fell from the trees before ripening,” said Nurul Islam, a farmer from Shibganj upazila in Chapainawabganj. He said mango trees in his area had initially blossomed well, but many of the mangoes had become victims of the attack by leaf hoppers caused by sultry weather from March 15 to 30. “We are cursed with Moha this year,” said Nurul. Horticulturists explained that Moha is a kind of disease that appears in the form of mould on leaves. It happens especially when the mist shrouds the nature during summer nights, another change in the weather pattern. They said adequate rainfall could save mango trees from this kind of diseases. The mango growers of Chapainawabganj and Rajshahi are worried as the number of trees bearing fruits is inadequate. The farmer said they generally used insecticides once a season but they were forced to apply it three times this year, but there was no impact. Shariful Islam, a mango trader of Lalbag village in Godagari upazila, said mango production was likely to suffer a setback this year due to unfavourable weather. The annual average mango production is about five lakh tonnes from over 45,000 hectares of land in eight districts under Rajshahi division including Chapainwabganj where mango grows on 22,000 hectares of land while it is about 8,500 hectares in Rajshahi. The unexpected sultry weather due to change in climate caused mangoes to drop prematurely, said agriculturist Dr Saifur Rahman. Most mango growers in the two mango producing districts have used pesticides and other chemicals at least 20 times for “protection and better yield”. Excessive use of toxic chemicals in the country’s mango producing zone is posing a serious threat to public health as well as to environment and wildlife.

NEW innovative lures for trapping major horticultural pests will soon give growers an effective tool for better on-farm integrated pest management.

Department of Agriculture, Fisheries and Forestry business manager Jodie Campbell said the new traps would help growers control both banana spotting bugs and fruit spotting bugs, leading to less crop damage and improved productivity.

“Banana spotting bugs and fruit spotting bugs are two major pests of a wide range of tropical and subtropical crops including avocado, macadamia, papaya, mango, limes and custard apples,” she said.

“These pests were notoriously difficult to monitor, which is a large reason why growers in tropical and sub-tropical regions of Australia were forced to use broad-spectrum cover sprays.

“After more than 20 years of research and development, DAFF entomologists are now seeing very promising results from these new lures that use pheromones to trap and monitor the bugs.

“The pheromone lures have been effective in attracting both male and female spotting bugs and the ‘sticky panel’ trap component we designed is highly effective at catching these bugs.

“We are now at the stage of working with a commercial partner to maximise the potential of the lures to benefit the Australian horticultural industry.

“This is great news for growers, who will be able to access this technology from around mid-2015.”

Organic Crop Protectants was selected as the commercial partner to take the innovative lure technology to the market.

“OCP is a well-qualified company that has been commercially focused in the business of integrated pest and disease management for over 20 years,” Ms Campbell said.

“OCP’s plan will be to support further research and optimise the lures and traps into an integrated pest management system.

“The aim is to provide effective integrated pest management tools that give farmers better confidence to make the transition to more sustainable farming practices.”

The selection of OCP as the commercial partner for the new traps was undertaken through an open, competitive tender process by DAFF and Horticulture Australia.
