The experiment entitled "Insecticides Application for the Control of Rice Pests," was conducted at the Research Experimental Rice Field of the Don Severino Agricultural College, Indang, Cavite from July to November 1978 to determine which method and kind of insecticides applied is best for the control of rice pest.
An area of 265 square meter puddy soil was divided into sixteen equal blocks constituting four treatments and four replications. Four seedlings of rice plant per hill were transplanted in straight rows at the distance of 25 x 25 cms. and fertilized with ammonium sulfate at the rate of 300 kilograms per hectare (150 kgs. for basal application and 150 kgs. for top dressing).
Different kinds of insecticides were applied in different treatments which are as follows: Treatment 1 - foliar spray using Azodrin 202, Treatment 2 - seedlings soaked using furadan 2F plus band application of furadan 3G, combined with foliar spray using Azodrin 202 at 70 days after transplanting, Treatment 3 - broadcasting of furadan 4G three times during its growth period and Treatment 4 - area that was not treated by chemicals or control.
Result of this study showed that treatment 53, the plant protected by the application of furadan 4G produced the least damage of whorl maggot, least percentage deadheart and white head and gave the highest computed yield per hectare of rice grains as compared to other treatments.
