Tomato (Solanum lycopersicum L.) is one of the most popular and widely grown vegetable crop of both tropics and subtropics of the world. It is a member of the family Solanaceae. Low tomato yields have been ascribed to a variety of issues, including poor seed quality, pest infestations and severe weather conditions. Insect pests are the most important of all known causes, causing significant losses at any stage of crop development. Many tomato producers are complaining about losses owing to sucking pests. Therefore, the study was carried out to compare the efficiency of different chemical insecticides against whitefly and thrips of tomato at Main Agriculture Research Station, Dharwad, Karnataka, during rabi, 2021-22. The experiment involved the treatments such as, T1-Thiamethoxam 25 WG @ 0.25 g/l, T2-Dinotefuron 20 SG @ 0.4 g/l, T3-Diafenthiuron 50 WP @ 1.0 g/l, T4-Acetamiprid 20 SP @ 0.2 g/l, T5-Flonicamid 50 WG @ 0.3 g/l, T6 - Spiromesifen 22.9 SC @ 1.0 ml/l, T7 - Spirotetramat 24 SC @ 0.5 ml/l, T8 - Untreated check. Among the various treatments imposed, the flonicamid 50 WG @ 0.3 g/l and dinotefuran 20 SG @ 0.4 g/l were found effective in reducing the whitefly and thrips population. Highest fruit yield was recorded in flonicamid 50 WG @ 0.3 g/l (39.00 t/ha) followed by dinotefuran 20 SG @ 0.4 g/l (37.00 t/ha). Similarly, the highest net return was registered in flonicamid 50 WG @ 0.3 g/l (1.83 lakh/ha) followed by dinotefuran 20 SG @ 0.4 g/l (1.60 lakh/ha). [ABSTRACT FROM AUTHOR]

The present experiment was conducted to assess the effectiveness of vermicompost, neem cake, pongamia cake, neem oil and pongamia oil on the activity of tomato thrips, whiteflies and mites under field conditions at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during rabi 2021-22. The results indicated that crop amended at planting with vermicompost (2.5 t/ha), neem cake (125 kg/ha), Pongamia cake (125 kg/ha) and followed by foliar spray of Azadirachtin 10000 ppm @ 2 ml/l was effective in keeping the density of sucking pests in check, being comparable to recommended insecticide. Significantly highest tomato yield (35.25 t/ha) was registered in the crop receiving VC (2.5 t/ha) + NC (1.25 q/ha) + PC (1.25 q/ha) - Azadirachtin 10000 ppm @ 2 ml/l. This was on par with VC (2.5 t/ha) + NC (2.5 q/ha) - Azadirachtin 10000 ppm @ 2 ml/l (34.10 t/ha). The untreated crop yielded the lowest (30.00 t/ha) tomato fruits. The research highlights the utility of organics in managing sucking pests of tomato that has potential export value. [ABSTRACT FROM AUTHOR]
