Pest control following natures lead

“Farm biodiversity can be improved by integrating border crops, trees, and animals. Farmers can also include trap crops-crops that attract insects away from the main crop-which include Indian mustard, sunflower, marigold, soybeans, and French beans, as well as crops that promote insect predators such as pulses for beetles, okra for lace wing, and coriander, sorghum, and maize for trichogramma (small wasps). Visual barriers can be used to help “hide” crops from pests. The diamond backed moth, for example, has to be able to see cabbage in order to find it-and destroy it before a harvest.

Nourishing the Planet saw some of these techniques being implemented at Enaleni Farm, a demonstration farm run by Richard Haigh in Durban, South Africa. Haigh cultivates traditional maize varieties that are resistant to drought, climate change, and disease, and he practices push-pull agriculture, which uses alternating intercropping of plants that repel pests with ones that attract pests in order to increase yields. He also applies animal manure and compost for fertilizer. Haigh likes to say that his farm isn’t organic, but rather an example of how agro-ecological methods can work.”
