Effect of seed treatment of sheath blight pathogen infected seeds of rice with fungicides on germination, growth and vigour of rice seedling. Kannaiyan, S.; Prasad, N. N. (Dep. Agric. Microbiol., Tamil Nadu Agric. Univ., Coimbatore 641 003, India). Madras Agric. J., 69(9), 585-9 (English) 1982. CODEN: MAAJAP. ISSN: 0024-9602. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Sheath blight disease (Rhizoctonia solani)-infected seeds of rice cv. ADT 31 were treated with fungicides and the seed germination, seedling growth, seedling vigor and the viability of seeds were studied after an 8-mo storage. The seeds were treated with the fungicides NF-18 [27079-29-4], Fifolatan [2425-06-1], Dexon [140-56-7], EL-273 [26766-27-8], Brassicol [82-68-8], Bavistin [10605-21-7], Captan [133-06-2], Demosan [2675-77-6], Vitavax [5234-68-4], Benlate [17804-35-2], Brestan [900-95-8], Agrosan [62-38-4], Thiram [137-26-8], Plantvax [5259-88-1], Agallol [123-88-6], and Daconil [1897-45-6] at 0.1, 0.2, and 0.3% levels. The seed treatment with fungicides have increased the seed germination, seedling growth, and vigor and maintained the viability ￡8 mo., except Demosan and Brestan which slightly inhibited the seed germination.

Control of peanut Cercospora leaf spot and web blotch: efficiency of fungicides and influence on yield

Control of peanut Cercospora leaf spot and web blotch: efficiency of fungicides and influence on yield. Gimenes-Fernandes, N.; Barreto, M.; Perecin, D. (Dep. Def. Fitossanitaria, UNESP, Campus de Jaboticabal, Brazil). Summa Phytopathol., 9(3-4), 186-95 (Portuguese) 1983. CODEN: SUPHDV. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) The efficiency of chlorothalonil [1897-45-6], captafol [2425-06-1], benomyl [17804-35-2], benomyl-maneb mixt. [39341-94-1], and ziram [137-30-4] for the control of peanut Cercospora leaf spot (C. arachidicola and C. personata) and web blotch (Ascochyta arachidis) was tested in the field. For the control of Cercospora leaf spot, benomyl + maneb, benomyl or chlorothalonil were more effective than captafol or ziram. For the control of web blotch, benomyl + maneb was slightly more efficient than other compds. and there were no differences between the treatments with chlorothalonil, benomyl, captafol, and ziram. The correlation coeff. between yield and no. of Cercospora leaf lesions was -0,95 and between yield and no. of leaflets with web blotch symptoms was -0,37.
