A facility has been launched in Kenya to aid commercial production of a protein bait to control fruit flies in Sub-Saharan Africa. The US$250,000 facility, which resulted from public-private partnership involving the International Centre of Insect Physiology and Ecology (icipe) and Kenya Biologics Ltd, will enable smallholders control fruit flies that devastate their fruits and vegetables.

Factsheet of the month: July 2015 – Prevention of powdery mildew on mango using cultural methods

20157800331The use of pesticides in Ethiopia has been increasing in recent years but it is thought that due to a lack of training and awareness, these chemicals are often being used unsafely and excessively. Many groups in Ethiopia are therefore raising awareness of Integrated Pest Management (IPM) in which control methods are selected based on their economic justification and level of risk to the environment. Cultural control methods do not involve the use of chemical pesticides and so are often less expensive to implement and safer for the environment.

This month’s Factsheet of the Month, ‘Prevention of powdery mildew on mango using cultural methods‘ provides information about using cultural control methods to reduce the incidence of powdery mildew in mango. This factsheet was written by extension experts in Ethiopia last year.

Mango production in Bangladesh

20157800221According to the Daily Star, mango production in Rajshahi and Chapainawabganj districts in Bangladesh might be hampered by unfavourable weather this year. The farmers are worried as large numbers of fruits, up to 70%, fell from the trees before ripening. Following the attack by leaf hoppers earlier in March, mango trees in that area are now affected by an undiagnosed disease which has symptoms described as mould on leaves. This unconfirmed disease could potentially be caused by powdery mildew (Oidium mangiferae), but reliable pathogen diagnosis is needed before advising management strategies.

For advice on how to prevent and manage mango pests and diseases, such as powdery mildew, anthracnose and mango seed weevil, review the Green Lists hosted on the Plantwise knowledge bank providing cultural and biological management options.

The Green Lists are produced by Plantwise for use by plant doctors and extension workers who provide advice to farmers. To see more about the content held on the Plantwise knowledge bank, please click here.

Factsheet of the month: May – Fruit Fly Control

Fruit fly control

Today, the European Union (EU) has imposed a ban on imports of Alphonso mango from India after authorities in Brussels found fruit flies infesting mango shipments earlier this year. This ban is likely to affect everyone in the supply chain – from growers to wholesalers to consumers.

Fruit flies are a major pest of mango and many other crops.  To find out how pheromone traps can be used to control mango, please read the ‘Fruit fly control’ factsheet, written by staff at the Ministry of Agriculture in Sierra Leone.

Factsheets for Farmers are produced by partners in Plantwise countries to communicate agricultural extension information. To see more about the content held on the Plantwise knowledge bank, please click here.
