Evaluation of Bioefficacy, Phytotoxicity of Fipronil 200 SC w/v against Pest Complex and its Safety to Non Target Invertebrates in Chilli

Abstract

Chilli, Capsicum annum (L.) belonging to the Solanaceae, is reported to be origin of South America. The green as well as ripened and dried fruits are commercial parts and one of the most imperative spicy vegetable used for making all types of Indian curries in habitual life. It was introduced in India by Portuguese towards the end of 15 th century and it is intensively cultivated in Andhra Pradesh, Maharashtra, Karnataka, Tamil Nadu, Rajasthan and in hilly areas of Uttar Pradesh (Ratnakumari et al., 2001). In India, chilli is grown in an area of 7.43 L ha, with a production of 14.53 L tons (Agricultural Statistics at a glance, 2015) and in Tamil Nadu, the production and productivity was 1, 70, 000 ha and 1,98, 3000 tons, respectively (Horticulture at a glance, 2015).Inspite of extensive cultivation, the crop is subjected to severe biotic stress all through their growth period. Chilli crop is infested by many insect pests, among which, thrips, Scirtothrips dorsalis (Hood), white mite, Polyphagotarsonemus latus (Banks), aphids, Aphis gossypii Glover and Myzus persicae Sulzer as sucking complex and tobacco caterpillar, Spodoptera litura (Fabricius) and pod borer, Helicoverpa armigera (Hubner) as pod borers (Rao and Ahmed, 1985) poses high

Performance of various pesticides against Yellow stem borer, Scirpophaga incertulas (Walker) of Basmati rice and effect on yield in Northern India

“…From the present study, higher grain yield and net pro t were recorded in the treatment Imidacloprid 17.8 SC @ 200ml/ha. which is agreement with the nding of Sangamithra et al, (2018) and Mishra et al, (2009). The best cost bene t ratio in the present nding was recorded with the treatment Imidacloprid 17.8 SC @ 200ml/ha (1:7.83) followed by Thiamethoxam 25 WG @ 100gm/ha (1:7.59) this nding was partially similar with the nding of Kumar and Kumar (2017).…”

Efficacy of Insecticides Against Major Sucking Insect Pests of Okra and Their Effect on Natural Enemies

“…Bisht et al (2017)revealed that thiamethoxam 25%WG @ 25g a.i/ ha was the best. Sangamithra et al (2018) found that the combination of insecticides with different modes of action and target group is effective. In case of fruit infestation (curled), lowest fruit infestation (9.56%) was obtained from T 6 (chlorantraniliprole + thiamethoxam) @ 0.75 ml/ l treated plots (Table 1).…”

Impact of IPM Modules on Natural Enemies in Okra

“…; Spider and coccinellids in pest management modules in okra -location I and IISangamithra et al, 2018;Randhawa and Pandey, 2020) were found safe for spiders and coccinellids. Emamectin benzoate, a synthetic derivative of avermectin (natural fermentation products of Streptomyces avermitilis) is a mixture of emamectin benzoate B 1 a and B 1 b.…”
