Between 2011 and 2015, CABI set up 22 Trichogramma rearing facilities as part of a project to promote the use of biologically-based Integrated Pest Management (IPM) for rice and maize crops. In addition to creating the Trichogramma rearing facilities, IPM strategies for rice and maize were developed in Southwestern China, Laos and Myanmar.

10 years ago the Coconut Rhinoceros beetle (CRB) was first discovered on the western Pacific island of Guam. Since then, these shoe-shine black, miniature invaders have spread to all parts of the island and are laying waste to the local coconut and oil palm population. The economy, culture and ecology  of Guam and other Pacific islands are intrinsically linked to the native palm species such that the rhino beetle poses a major threat. The indigenous peoples of Guam have a long history of weaving palm fronds, an artistry that is now at risk due to the rhino beetle. These trees are a symbol of tropic paradise, a motif that drives Guam’s primary industry; tourism. Continue reading

Plantwise goes mainstream in Myanmar agriculture

by Dr. Kyin Kyin Win, Deputy Director (Plant Protection Division, MOALI)

A major outcome of the two-year  pilot programme of Plantwise in Myanmar was the  recommendation from Dr. Tin Htut, the Permanent Secretary of the Ministry of Agriculture, Livestock and Irrigation (MoALI) to develop a Myanmar Plant Health System Development Strategy (MPHSDS) to guide the future development of the plant health system in Myanmar. Following this, a write shop with senior officials of MoALI was held on the 22nd April 2016 in NayPyiTaw,. The first draft of the MPHSDS was prepared by CABI using as reference documents the Myanmar Rice Sector Development Strategy (MRSDS) and Climate Smart Agriculture Development Strategy.

The rice ecosystems are inhabited by more than 100 species of insects. Twenty of them can cause potential economic losses. With the change in the climatic factors and modern cultural practices adopted for production a drastic change has been caused in the pest scenario in the recent past. Besides stem borer, gall midge, brown plant hopper and green leafhopper which were the major problems in past, several other relatively minor pests such as leaf folder, armyworms, cut worms etc. have gained importance. In a study conducted by the International Rice Research Institute (IRRI), it was found that, on average, farmers lose 37% of their rice yield to pests and diseases, and that these losses can range between 24% and 41% depending on the production situation (http://irri.org). All the pests are generally kept under check by their natural enemies (parasitoids and predators) by feeding on them. The food web of their relationships prevents the explosion of their populations and keeps them under economic thresholds mimimising the pesticide use.

Plantwise plant clinics are currently operating in 31 countries in Asia, Africa and Central & Latin America. Thousands of farmers come to these clinics for advice on managing their crops, particularly crops that are being affected by pests or disease. The video below gives the story of a farmer in Puducherry, India, who got advice on how to manage the rice in her paddy field that had turned yellow during a cyclone.
