Maize is successfully grown twice a year in Pakistan but spring maize is becoming more popular amongst maize growers due to better adjustment in the existing cropping pattern. A large number of insect pest are attacking maize crop whereas maize borer and shoot fly are more important. New trends are adopted in the protection of maize crop viz., seed treatment, foliar/granular application at early stages of plant growth against existing techniques and development of resistant variety. Seed was treated before sowing with different insecticides and Confider WS70 was proved better in controlling insect attack. Foliar application was economical at seedling emergence in spring crop whereas spraying of pesticides to the seedlings one week after completion of its emergence in kharif crop significantly controlled shoot fly (Atherigona soccata Rond.) and minimized the attack of maize borer (Chilo partellus Swin.). Evolution of resistant maize varieties is more important, economical for the growers, and safe. BR-1 and BR-2, tolerant to maize borer, shootfly and foliar disease complex were evolved and their yield trials are under way for giving agronomic recommendations.
