Farmer field schools (FFS) originally were developed for rice in Asia by the Food and Agriculture Organization of the United Nations (FAO) for teaching integrated pest management. These were season-long courses involving 25 farmers and a trained facilitator. The main focus was promoting learning by discovery, which included hands-on training activities such as insect zoos and the use of field e...

The population consisting of 210 F2:3 individuals from the cross between BPT-5204 (highly susceptible to sheath blight) and ARC-10531 a land race from Assam (moderately resistant to sheath blight) was analyzed to identify the markers associated with sheath blight resistance and to study any association of any morphological trait to disease incidence. The frequency distribution curve of F2:3 pro...

The recent outbreak of the southern corn blight is caused by race T of fIel1l1intlzosporiulIl lIlaydis, a species in the fungus genus Hel1l1intlzosporiU1I1 which consists of about 175 species, worldwide in distribution, on grasses. Three species of HellllintlzosporiulIl-H. lIlaydis, H. turciculIl, and H. carbonUIIl-attack corn and are placed in the genus Bipolaris. The southern corn blight fung...

Foliar blight of potato caused by Aspergillus terreus is reported for the first time. The blight is characterized by a brown leaf apex amounting to 35‒65% of the total leaf surface. The pathogen was identified on the basis of morphological characters and ribosomal DNA sequence data. The fungus produced effuse white colonies, branched hyphae, broom-like conidiophores, and globose accessory conid...

The toxic effects of the Fusarium graminearum trichothecene toxin deoxynivalenol were determined on ribosomes and leaf tissues of the fusarium head blight-resistant spring wheat cultivar Frontana and the susceptible spring wheat cultivar Casavant. The use of a poly-U-directed 14C-phenylalanine and deoxynivalenol ribosome-binding assays provided evidence of resistance to the protein-synthesis in...

Bacterial blight (BB) caused by Xanthomonas oryzae pv. oryzae (Xoo) has become one of the most devastating diseases for rice, a major food source for over half of the world populations. To investigate the roles of protein phosphorylation in rice bacterial blight resistance, a quantitative phosphoproteomic study was conducted in rice variety IRBB5 at 0 h and 24 h after Xoo infection. 2367 and 22...

The theory has recently been put forward by Renwick (1972a) that anencephalus and spina bifida are caused by exposure early in pregnancy to potatoes which are affected by blight or are imperfect for other reasons. In support of this, a temporal correlation was claimed to exist between the severity of blight and the frequency of anencephalus, largely because of a strong correlation between the a...

This Article explores two explanations for why New Jersey and New York take different approaches to judicial review of exercises of eminent domain. Part I examines the approach of both states and their differing procedures for review of administrative agency determinations. Part II discusses how each states’ courts and legislatures define “blight.” Part III examines how New York’s approach leav...

(57) ABSTRACT Disclosed are methods of identifying subspecies of Crypto coccus flavescens and methods of treating or suppressing Fusarium head blight with the different Cryptococcus flave scens species. In particular, two genotypes, Genotypes A and B, were identified using the disclosed real time PCR tech nique. The following Cryptococcus flavescens strains were identified as being either Genot...
