  • A questionnaire survey of 100 smallscale cotton growers was conducted in two cotton-growing provinces of Mozambique to assess the constraints faced by the farmers in relation to the timing of insecticide application. The results showed that majority of the farmers started spraying too early (four weeks after germination) and were unaware that such sprays reduced the population of natural enemies of insect pests and might not lead to increased yields. The farmers applied an average of three sprays in the cotton growing season, about half of them according to pest observance and 41 % by following instructions of extension officers, but were constrained by the unavailability of insecticides and sprayers. Another constraint was lack of information on the timing of insecticide application. More than half of the farmers had suffered mild insecticide poisoning and needed more effective training on the judicious and safer use of insecticides, integrated with non-chemical pest management practices.
