Rice sheath blight

Validamycin. Validamycin A (VM-A) is a new antifungal antibiotic recently developed in Japan for the control of rice sheath blight (50-52). It was isolated from the culture filtrate of Streptomyoes hygroseopicus var. timoneus, which also produced five... [Pg.177]

HI 26 Trehalase and inositol synthesis Glucopyranosyl antibiotics Validamycin Specific for rice sheath blight Rhizoctonia solani)... [Pg.429]

Inhibitors of fungal glucan synthesis are of microbial origin, produced by Strep-tomyces hygroscopicus var. limoneus (HI) and of S. cacaoi var. asoensis (H2) (Table 12.13) [19]. Validamycin is a specific compound for the control of rice sheath blight, whereas polyoxins inhibit a target site that, potentially, is present in all As-comycetes and Basidiomycetes. Nevertheless, the market importance of polyoxins remains limited. [Pg.429]

Organic acids and their derivatives find use in many other applications outside the herbicide area. Deet, N,N-diethyl-m-toluamide, is widely used as an insect repellent. Another toluamide is meopronil, a fungicide that controls rice sheath blight. The natural and synthetic pyrethroid insecticides are acid esters, which are discussed more fully later. [Pg.1158]
