Abstract

Spraying of diflubenzuron at 100 g a.i./ha after spike emergence (10–15 cm from flag leaf) was more effective against early larval stages of millet spike worm, Heliocheilus (=Raghuva) albipunctella De Joannis, than spraying the crop at female flowering or at the milky grain stage.

Résumé

La pulverisation de diflubenzuron appliquée à la dose de 100 g m .a./ha après la sortie de l'épi (10–15 cm de la gaine foliaire) s'est montrée efficace contre les premiers stades larvaires de la mineuse de l'épi, Heliocheilus (=Raghuva) albipunctella De Joannis, par rapport aux pulverisations faites à la floraison femelle ou au stade de grains laiteux.
