CABI organized a five-day course on Integrated Pest Management (IPM) at the Graduate School of the Chinese Academy of Agricultural Science (CAAS) in Beijing on 13 to 17 February 2017. The course was delivered by CABI IPM expert Stefan Toepfer, a visiting professor at the Institute of Plant Protection in CAAS, where the joint Chinese Ministry of Agriculture-CABI laboratory is also located.

Hy Broey, a farmer from Choeung Tik Khor village in Prey Veng Province, Cambodia, came with her problem to the plant clinic. She had many problems in rice planting and production, especially during the tillering stage. By attending plant clinics in her village she has learned how to solve her agricultural problems.
Mr Tep Say, the plant doctor, had identified the problem and told her that it was caused by stem borer. He showed her the affected part: dead hearts or dead tillers that can be easily pulled from the base during the vegetative stages. Also, during the reproductive stage, the plants were showing whiteheads: emerging panicles were whitish and unfilled or empty. He showed her tiny holes on the stems and tillers. He told her that she should synchronize planting, and use a recommended resistant variety. During the harvesting she should cut rice near the stem base in order to remove and kill all larvae and pupae. She should also try to conserve predators and try to catch the adult stem borer moths. If she removes all the affected plants, and only if the insect still persists, she can spray a named insecticide in order to kill the insect.
Later the plant doctor also visited the farmer’s field and gave her IPM recommendations. He told her and her husband not only to rely on chemical control but also include cultural practice to improve crop yields, and to protect the environment, thus allowing the natural enemies like dragonflies to breed and help control the adult stem borer moth.
The plant doctor had a follow-up visit to the farmer to see the implementation of his advice. After attending the plant clinic, Hy Borey and her husband changed their habit of only relying on chemical sprays and practised with IPM technique as provided by the plant doctor. They got good results and harvested a good crop. At the harvesting time the farmer was very happy since she got a better yield. Before visiting the plant clinic she got only 2.5 ton/ha but this year after visiting the plant clinic the yield had increased to 3.7 ton/ha. Before visiting plant clinics, she sprayed pesticide 3 times per season for management of pests but after visiting the plant clinic she learnt to apply the IPM method to control insects and diseases, and no more spraying of chemicals was required in this season. She was very happy and thanked CABI’s Plantwise plant clinic program for the support to help farmers in Prey Veng, and other provinces as well.
A recent article in the Sri Lanka Plant Protection Industry Journal highlights how the crop clinic concept in Sri Lanka has promoted effective, judicious use of pesticides. PT Bandara and WMDH Kulatunga describe how the Permanent Crop Clinic Programme (PCCP), established in 2009, provides effective advice that both prevents the destruction of natural enemies due to the use of broad spectrum pesticides, and reduces outbreaks of Chronic Kidney Disease, which has become a major socioeconomic issue due to pesticide residues in food. Access to Pest Management Decision Guides and a knowledge bank of information helps plant doctors to find alternative advice where appropriate for prevention, monitoring and control of crop pests in order to ensure minimal risks to human health and the environment.

A recent IPM workshop in Ethiopia focussed on the tomato leafminer – a pest that causes devastation on tomato crops in Europe, Africa and South America. This video shows how the workshop attendees dedicated their time to finding out more about the pest, seeing it in the field, and working on recommendations for control.
Here’s a taste of some of the latest stories about plant health, including a new banana disease identified in Africa, ways to deal with oil seed rape pests after the neonicotinoid restrictions and the role of agricultural cooperatives and storage in rural Ethiopia.
In the first half of 2013 two million red palm weevils were removed from farms in Abu Dhabi using pheromone traps. The large number of red palm weevils in the area prompted the launch of the initiative, which forms part of the Abu Dhabi Farmers’ Services Centre’s (ADFSC) Integrated Pest Management project. The project was implemented in coordination with the Abu Dhabi Food Control Authority (ADFCA) and will run throughout the rest of 2013 and 2014. This project aims to control palm tree pests while minimising pesticide usage, by increasing the knowledge and capabilities of workers to enable them to implement the best control methods for pests.
