Two Plant Health Rallies have recently been held in Grenada to raise awareness of the West Indian Fruit fly and promote the control of this pest using fruit fly bait stations. The rallies, which were organised in collaboration with the Ministry of Agriculture, Lands, Forestry, Fisheries and the Environment, were aimed at local farmers with the first attracting 25 attendees and the second around 12. The farmers were given practical advice on how to make and use bait stations which they were able to take away with them afterwards. Thaddeus Peters (MoA) presented at one of the rallies explaining what damage the West Indian fruit fly causes and how the MoA and farmers can both play a part in controlling the pest.  Continue reading

Banana bacterial wilt leaves thousands hungry in Tanzania

According to IPP Media, over 8,000 people in 15 villages in Kagera region of Tanzania are in dire need of food relief following an outbreak of banana bacterial disease that has destroyed 90% of the banana crop. Bananas are the staple food for people in the region. Adam Malima, Deputy Minister for Agriculture, Food and Cooperatives, told the National Assembly earlier this week that the government has allocated 300 tonnes of maize to be distributed to people in the area.

Banana bacterial wilt (or “banana slim”) is easily spread through pollinating insects, tools and planting material. Disease management is notoriously difficult, often involving cultural methods that can be impractical for smallholders. One easy method of prevention involves breaking off the male flower bud using a fork-shaped stick.

The male flower bud is often where the bacteria enters the plant. Pollinating insects collect nectar from the bud and carry nectar from plant to plant, transferring the bacteria at the same time. Removing the male bud soon after formation of the last cluster stops insects from spreading the disease. A forked stick can be used to twist and break the bud. This is better than cutting the bud off with a knife which might spread the bacteria.
