The present study was conducted to manage the thrips (Thrips tabaci) on onion varieties namely Chiltan-89, Phulkara, Trichmir, Gulnar, Nasarpori using chemical pesticide (Chlorpyrifos) in field. For experimentation, the randomized complete block design was used by performing three treatments in agriculture vegetable and seed farm Sariab, Quetta. Three sprays of Chlorpyrifos of equal concentration were applied on the five mentioned different onion varieties. Thrips were recorded before starting the treatments and monitoring thrips mortality rate at the intervals of 24 hours (hrs), 48 hrs, 72hrs and a week after each spray. Results revealed that the pesticide showed high significant control of thrips infestation of Chiltan-89 variety after 24 hrs at P value<0.0001 in all three treatments: 48 hrs (P<0.001) in treatment 1 and P value<0.0001 for T2 and T3: 72 hrs (P<0.05, P<0.001 and P<0.0001) for T1, T2 and T3, and (P<0.05 and P<0.0001) after a week in T2 and T3. The same pesticide showed comparatively least control of Trichmir at P value less than 0.001 and P<0.0001 after 24 hrs for T2 and T3: 48 hrs (P<0.05) for both T2 and T3: while after 72 hrs and one-week interval P<0.0001 and P<0.05 was noted for treatment 3, respectively. Furthermore, treatment 3 showed more significant results then treatment 1 and 2. Whereas more positive control was observed after 24hrs in all the five varieties.
