A. Sivapragasam, . and Loke W. H., . and M. Ruwaida, . (1999) A strategy towards managing the agromyzid leafminer Chromatomyia horticola goureau on chrysanthemums through the selective use of insecticides. [Proceedings Paper]
Abstract
A field trial was conducted to evaluate the strategy of reducing pesticides use on chrysanthemums infested by the agromyzid leafminer Chromatomyia hortieola. The insecticide rotation strategy whereby insecticides with differing modes of action and selectivity were used on a weekly rotational basis was advocated compared to the twice weekly sprays of a suite of insecticides applied indiscriminately by the grower. Results showed that although the costs of pesticides were relatively higher there were definite advantages in terms of reduction in the frequency of sprays and higher levels of parasitism without compromising the yield of marketable flowers in the treatment where insecticides were used in rotation than in the growers; plot.
