Over 2,600 transgenic rice plants in nine strains were regenerated from >500 independently selected hygromycin-resistant calli after Agrobacterium-mediated transformation. The plants were transformed with fully modified (plant codon optimized) versions of two synthetic cryIA(b) and cryIA(c) coding sequences from Bacillus thuringiensis as well as the hph and gus genes, coding for hygromycin phos...

The present investigation entitled Evaluation of the efficacy some insecticides against rice yellow stem borer, Scirpophaga incertulas (Walker) was undertaken at MAE Farm, Regional Agriculture Research Station, Karjat (M.S.) during Kharif 2018. overall mean borer infestation (dead heart) varied from 1.23 – 7.50 per cent. T5 (Flubendiamide 20 WG @ 0.005%) recorded minimum (1.23%) and which signi...

In this study, the botanical pesticide Suaeda maritima (L) leaf extract was evaluated against yellow stem borer (YSB), Scirpophaga incertulas Walker (Lepidoptera: Pyralidae), and bacterial blight disease Xanthomonas oryzae pv. (Xoo), of rice. S. leaves were powdered subjected to various organic solvents, like petroleum ether, ethyl acetate, methanol based on polarity, in which acetate produced ...

Two species of Trichogramma wasps were assessed for their effectiveness against yellow stem borer Scirpophaga incertulas. A laboratory cage test with T. japonicum and T. chilonis showed that both species parasitized yellow stem borer egg masses at 60.0% ± 9.13% and 40.7% ± 7.11%, respectively, with egg parasitism rates of 15.8% ± 22.2% for T. japonicum and 2.8% ± 5.0% for T. chilonis. Once the ...

Abstract Jajar legowo (Jarwo) is a rice planting system that widely practiced by farmers, but information regarding its effects on pests and natural enemies limited. This study aimed to identify how the Jarwo affects population damage intensity of yellow stem borer ( Scirpophaga incertulas ) predators. The research was conducted in Wonosari-Klaten, Central Java, during dry season 2020. 2:1 used...

Rice (Oryza sativa L.,) plants release a complex profile of volatile organic compounds. Present study investigates the differences in compounds from four rice landraces viz., Karuthakar, Norungan, Thavala Kanan and Varappu Kudaichan each under conditions like healthy, mechanically damaged, ones infested by brown plant hopper Nilaparvata lugens Stal yellow stem borer Scirpophaga incertulas (Wlk....
