The tomato leaf miner, Tuta absoluta, is a devastating pest of tomato. Originating from Latin America, T. absoluta has spread via infested fruits and packaging material to Europe, North Africa and the Middle East. Given its potential for crop destruction and rapid reproduction, it quickly became a key pest of concern in East Africa. Its primary host is tomato, but it also affects potato, aubergine, beans and others. Continue reading →
Greater involvement of women in plant clinics has improved the climate resilience of the farmers in Rohal Suong village, Cambodia. Women farmers play a critical role in agricultural production and food security, as well as household welfare in most Southeast Asian countries. According to a Census of Agriculture in Cambodia in 2013, of the 82% of Cambodians engaged in the agriculture sector, at least half of them were women.
The adoption of fertilizer trees on farms is a simple and effective way to improve soil fertility, food productivity and therefore contribute to food security. Yet, there is still little empirical research that documents the impact of fertilizer trees on food security among smallholder farmer households. Researchers from the World Agroforestry Centre carried out a study in Malawi to analyze the impact of the adoption of fertilizer trees on food security among smallholder farmers
A severe infestation of the papaya mealybug (Paracoccus marginatus) nearly wiped out papaya orchards in Pakistan before the largely farmed country decided to replace conventional chemical pesticides that were ineffective with natural predators that proved to be successful.
The system was developed by agro-biotechnologists and entomologists at the Pakistani chapter of the UK-based Centre for Agriculture and Bioscience International (CABI) who introduced the use of Acerophagus papayae, a parasitoid (insects whose larvae parasite upon and eventually kill the host), to effectively control the mealybug infestation.
Different doctors treat different types of diseases. When the villagers of Rohal Suong in Cambodia feel sick, they can consult a doctor. Now when their crops are sick, they can also go to another doctor, a plant health advisor, who can provide information on the best methods to treat crop pests and diseases.

Computer animations are a rather special and exciting communication medium. For example, they can be used to illustrate the basic biology of pests and diseases and explain control measures. Animations are also an effective way to show changes that occur over a long time or at the landscape, watershed or even the global level. A combination of animation with spoken explanations can make such phenomena much easier to grasp. Being able to ‘see’ the phenomenon helps viewers imagine why individual or collaborative actions may be needed to address otherwise hidden problems. Continue reading →
