Efficacy of Insecticides Against Rice White Backed Planthopper
Indian Journal of Entomology, 2023Efficacy of some insecticides (pymetrozine 50WG, sulfoxaflor 24SC and imidacloprid 17.8SL) was evaluated against rice white backed plant hopper (WBPH) Sogatella furcifera Horvath. Sulfoxaflor 24SC @218.7 g a.i./ ha and pymetrozine 50WG @ 187.5 g a.i./ ha gave significantly results (7.57 and 7.82/ hill, respectively).However, highest grain and straw ...

Mechanisms of Rice Planthopper Resistance to Insecticides
2014History of insecticidal control of rice planthoppers in Asia and associated resistance development is summarized. Rice planthoppers have developed resistance against all the insecticides that were commonly used. Experiences of past 30 years of chemical control of the rice planthoppers in many parts of Asia confirm that the use of any kind of ...

Can polycultural manipulation effectively control rice planthoppers in rice-based ecosystems?
Crop Protection, 2011Abstract Rice planthoppers (mainly Nilaparvata lugens (Stal) and Sogatella furcifera Horvath) are the most destructive rice pests throughout southeastern and eastern Asia. Planthopper feeding often causes “hopper burn” and reduces rice yields. Currently, insecticide use is the sole pest management option available to most Chinese farmers. Because

Of 15 planthopper resistant varieties evaluated for resistance to Sogatella furcifera, nine had high levels of resistance. Among the IR varieties, IR 36 and IR 56 had field resistance to Sfurcifera as indicated by their susceptibility in the standard seedbox test and resistance as older plants in the modified seedbox test. Insect growth and development,

The ROI of Rice Planthopper by image processing
2017 International Conference on Applied System Innovation (ICASI), 2017Rice Planthopper (RPH) infestation in paddy field is a serious disaster in Asia every year. Finding RPHs based on image processing is an important thing before RPHs growth. We propose a region of interest (ROI) method to detect RPHs clearly. First, get rectangle ROI in HSV space and do color analysis. By using decision tree algorithm, classify analytic

Resistance to Planthoppers and Southern Rice Black-Streaked Dwarf Virus in Rice Germplasms
Plant DiseaseThe damage caused by the white-back planthopper (WBPH, Sogatella furcifera) and brown planthopper (BPH, Nilaparvata lugens), as well as southern rice black-streaked dwarf virus (SRBSDV), considerably decreases the grain yield of rice. Identification of rice germplasms with sufficient resistance to planthoppers and SRBSDV is essential to the breeding ...
