“…Bharpoda et al (2014) found that diafenthiuron 50 WP (at 0.05%) was the most effective compared to imidacloprid 17.8 SL (at 0.008%) against B. tabaci. Rajasekhar et al (2018) observed that diafenthiuron 50% WP @ 1.25 g/ l was found effective in cotton. Thus, two foliar sprays of diafenthiuron 50WP 350 g a.i./ ha at 85% emergence mixed with castor oil @0.05% was superior as compared to without adding castor oil as shown by Boulehya et al (1997).…”

A field experiment was conducted to evaluate insecticides against the whitefly Bemisia tabaci Genn. in potato at the Agricultural Research Station, Kota, using variety K Bahar during 2018-19 and 2019-20. Based on pooled data, results revealed that two sprays of diafenthiuron 50WP 350 g a. i./ha mixed with castor oil @ 0.05% at 10 days interval gave maximum mortality (82.0%), maximum tuber yield (24.7 t/ha) with (ICBR 1:2.1) which was at par with two sprays of diafenthiuron 50WP 350 g a. i./ha (without mixed castor oil) at 10 days interval (78.0%) with tuber yield (23.8 t/ha).

“…In the present experiment also, disease reduction was found with insecticides but results of foliar spray with imidacloprid and fipronil were at par with untreated plot. Rajasekhar et al [6], who tested 8 insecticides against whiteflies of cotton under normal and high density planting system, found that diafenthiuron 50% WP @ 1.25 g/litre was effective in reducing whitefly population followed by flonicamid 50%WG@ 0.3 g/litre and acephate 75 SP@ 1.5 g/ litre, but promising results were not obtained with imidacloprid 17.8% SL and fipronil 5% SC. Shirshikar, [7] recorded the use of imidacloprid for seed treatment along with imidacloprid foliar spray and this treatment were found to be useful in the management of sunflower necrosis disease.…”

A field experiment on management of Sunflower Necrosis and Sunflower Leaf Curl disease was conducted for three years during rabi season at Main Agricultural Research Station, Raichur. The experiment was planned with seven treatments (six insecticides and one untreated) in three replications for three successive years i.e., rabi 2016-17, 2017-18 and 2018-19. The insecticides used were imidacloprid 17.8 SL, fipronil 5 SC, triazophos 40 EC, diafenthiuron 50 WP, flonicamid 50 WG and spiromesifen 24 SC. For six treatments (T1 to T6) seed treatment was done with imidacloprid 600 FS and for T7 was maintained without seed treatment. Pooled analysis revealed that the treatment T4 :(Seed treatment with imidacloprid 600 FS@ 5ml/kg seed+ foliar spray with Flonicamide 50WG @ 0.25g/l at 30, 45 and 60 DAS recorded the lesser Sunflower necrosis and Sunflower leaf curl incidence of 4.21% and 4.54% respectively with higher yield of 1630 kg/ha, which is followed by the treatment T5 : (Seed treatment with imidacloprid 600FS @ 5ml/kg seed + foliar spray with Diafenthiuron 50 wp @ 1gm/lit at 30, 45 and 60 DAS) recorded Sunflower necrosis and Sunflower leaf curl incidence of 6.34% and 7.06% respectively with higher yield of 1560 kg/ha and both were at par. Both the treatments recorded B:C ratio of 1.76 and 1.59 respectively. Higher incidence of Sunflower necrosis and Sunflower leaf curl 10.70% and 18.46% respectively and lower yield of 968.4 kg/ha was recorded in untreated control.
