Abstract:
The trial laid out in factorial randomized design (FRBD) with three replication. The two factors included seven chemicals including untreated control as a factor one and two label claim and university recommendation dose of each chemicals/insecticides applied against sucking pests as second factor for revalidation. The results indicated that the recommendation dose of acephate @ 750 g a.i./ha (0.32 aphids/three leaves) and label claim dose of diafenthuron @300 g a.i./ha (0.39 aphids/three leaves) significantly superior over all other dosage against aphids. acetamiprid 20 SP @ 20g a.i./ha was found significantly superior in lowering the population of jassid (4.30 jassids /three leaves, recommended dose of fipronil 5 SC @ 50 g a.i./ha recorded significantly lowest population of thrips (3.22 thrips / three leaves) and doses of diafenthuron 50 WP and fipronil 5 SC were recorded significantly least number (3.38 and 3.62 whiteflies / three leaves) respectively, maximum seed cotton yields of 10.87 and 10.24 q/ha were recorded in the university recommended dosages of fipronil 5SC @ 50 g a.i./ha and acephate 75 SP @ 750 g a.i./ha respectively.
