CABI has joined forces with the ISEAL Integrated Pest Management (IPM) Coalition in the fight to implement better, less chemical-dependent, ways for farmers to manage agricultural pests and diseases that account for around 40% of lost crops worldwide. By linking with the Plantwise Knowledge Bank, the coalition aims to share knowledge on sustainable pest management strategies, strengthen knowledge exchanges on alternative methods for pest management, as well as identifying and focusing on specific pest-disease.
A graduation ceremony held on 17 November 2017 in Engelberg, Switzerland, celebrated the successful completion of the 2017 Masters of Advanced Studies in Integrated Crop Management (MAS in ICM) programme by a number of international students.
Coordinated by CABI and the University of Neuchâtel, the MAS in ICM programme provides students with a comprehensive understanding of the principles of good crop management, with an emphasis on productivity and environmental sustainability.
Farmer representatives and project team members of Rohal Suong Climate-Smart Village in Cambodia learn about rice pest management in light of climate change.
Many people attribute floods, droughts and cyclones to climate change and these natural disasters impact greatly on agricultural productivity. But recent scientific evidences show that pests are getting a boost from climate change. The increasing temperature and erratic rainfall cause pests and diseases to thrive and infest crops in wider ranges of places globally.
Brasso Secco is a pristine environment located in the Northern Range of Trinidad in close proximity to the world famous Asa Wright Nature Centre. This farming community, among others, is nestled deep in the bosom of the of the Northern Range where approximately 300 family farms depend on Christophene production for their economic survival and well-being. Agriculture, and in particular “Christo” as the crop is fondly called, is the main source of income to more than 75% of them. Any major pest or disease could be devastating not only to the livelihood of these families, but also to the country’s environment if its control results in the inappropriate use of pesticides.
An outbreak of Gummy Stem Blight occurred 11 years ago and the disease is now endemic, affecting 100 percent of farms. Could an Integrated Pest Management (IPM) strategy be adopted to control this fungal disease and to protect the livelihoods of farmers while protecting this pristine environment? Continue reading →

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.
Increasing the production of food in an environmentally sustainable way is a major global issue. A report produced by the UK Cabinet Office in 2008 predicted that the global population will rise to 9 billion by 2050 from a current 6.8 billion. This increase in population will substantially increase demand for food, with food production needing to increase by 70% in the next 40 years whilst using the same agricultural footprint and without depleting natural resources. This challenge will require collaboration between universities, research institutes and industry in order to make the considerable advances in technology required to feed a growing population. There is now increasing concern that there are too few specialist graduates in the UK with the expert knowledge and skills required to tackle the issues surrounding global food security.
Transgenic Bt crops have been grown around the world since the 1990s and have contributed to increased yields by controlling agricultural pests. Due to the importance of this technology, there has been continuous study into the development of resistance to Bt crops and how best to avoid this happening. A recent investigation into the rapid spread of Bt resistance in South Africa has revealed one of the more surprising discoveries to date, that the maize stalk borer (Busseola fusca) has evolved Bt maize resistance inherited as a dominant trait for the first time. This has significant impacts on the management of Bt crops, as current methods for sustaining susceptibility rely on the recessive inheritance of Bt resistance.
