Rice is the major staple food in Jharkhand India and threatened by various biotic abiotic stresses. Among insect pests that imperil rice cultivation Jharkhand, yellow stem borer (Scirpophaga incertulas Wlk.) one of most notorious ones. The present investigation was conducted Kharif 2018 to study bioefficacy certain chemical insecticidal treatments against borers measured terms mean values dead ...

Several physical and chemical attributes of rice were evaluated to determine which character would be best to use to assess multiple rice varieties for resistance to the lesser grain borer, Rhyzopertha dominica (F.). Laboratory tests were conducted on single varieties of long-, short-, and medium grain-rice to develop procedures and methodologies that could be used for large-scale screening stu...

With the widespread adoption of high yielding rice (Oryza sativa L.) varieties and accompanying changes in cultural practices, leaf folder [Cnaphalocrocis medinalis (Guenee)] yellow stem borer [Scirpophaga incertulas (Walker)] has attained status major pests influence yield if proper timely management practices are not adopted. For effective these pests, identification new molecules with novel ...

Sodicity tolerant rice culture TR 05031, a derivative of the cross ADT 39 x CO 45  was released as Rice TRY 4 during year 2021 mid early duration variety  with 127 days high yield,  high milling (68.1 %)  and head recovery (57.2 %). Twelve years testing across 181 locations in Tamil Nadu revealed that culture  is yielding (5730 kg/ha 22.00 per cent increased grain yield...

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 ...

Developing and cultivating new promising rice lines with high yield potential blast disease resistance is an important goal of rice breeding. The study was to evaluate some developed new elite rice lines for yield, resistance, effective genes Pyricularia grisea stem borer insect as well assessment of the genetic diversity in these using microsatellite markers. Significant differences were found...

among several pests of rice as one of the main agricultural products in iran, rice borer, chilo suppressalis is one of the most important pests of this crop. use of pesticides coincided with the occurrence of this pest in the northern region of iran in 1972. at present in order to control this pest, more than 12000 tones of pesticides granules are used annually. ecological effects of pesticides...

The Mexican rice borer, Eoreuma loftini (Dyar) (Lepidoptera: Crambidae), is the key pest of sugarcane (Saccharum spp.) in Texas; it can attack several grassy crop and noncrop host plants and has spread into Louisiana. Through small-plot, commercial field, and pheromone trap experiments, this study demonstrates that the pest uses corn, Zea mays L., more than sugarcane and sorghum, Sorghum bicolo...
