Push-pull technology Push-pull is a habitat management strategy developed and implemented to manage pests such as stem borers, striga weed and address soil degradation, which are major constraints in maize production in Africa. The technology entails using a repellent intercrop (Desmodium as a “push”) and an attractive trap plant (Napier/Brachiaria grass as a “pull”). The […]

Ch 15: Don’t panic! Maize plants can compensate significant damage by the Fall Armyworm
Damaged plants can scare farmers. Never before have they seen this type of damage, where the insect eats through so much of the leaves. Farmers know about stem borers, but because they aren’t often seen (hidden in the stems), they don’t often scare farmers like this new pest, the Fall Armyworm. The spectacular-looking damage is […]
Ch 3: Managing FAW
The most promising options for the management of FAW by African smallholders are presented below, building on experiences from the Americas and latest research available in Africa, reflecting IPM strategies. These can be tested out in FFS as appropriate. Seeds and varieties Seed treatment might prevent early damage of the seedlings after germination. Longer-term solutions […]
Ch 2: Differentiating the Fall Armyworm from other worms
Other pests of maize are present in Africa which resemble to some degree the FAW. You can differentiate them by learning to identify the worms themselves at their different stages, and the type of damage they produce. Below are different species of maize stalk borers and their life stages. The most important stem borers pests […]
