Incorporating fungicides into fluid drilling gel to control damping-off of guayule

Incorporating fungicides into fluid drilling gel to control damping-off of guayule. Richardon, J. M.; Stutz, J. C.; Backhaus, R. A. (Div. Agric., Arizona State Univ., Tempe, AZ 85287, USA). HortScience, 20(4), 717-19 (English) 1985. CODEN: HJHSAR. ISSN: 0018-5345. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Etridiazole [2593-15-9], etridiazole/thiophanate [23564-06-9], fenaminosulf [140-56-7], Captan [133-06-2], and pentachloronitrobenzene (PCNB) [82-68-8] were tested for prevention of damping-off of guayule (Parthenium argentatum) seedlings in greenhouse tests. Fungicides were incorporated into a magnesium silicate fluid drilling gel contg. pregerminated seeds. The seeds were sown into vermiculite and inoculated with Pythium debaryanum or Rhizoctonia solani. Phytotoxic levels of the fungicides were detd. PCNB was very effective in controlling damping-off caused by R. solani. Captan and fenaminosulf provided >50% protection from damping-off caused by P. debaryanum. Etridiazole and etridiazole/thiophanate controlled preemergence damping-off, but did not control post-emergence damping-off caused by P. debaryanum.

Screening of fungicides to control angular and floury leaf spots of beans

Screening of fungicides to control angular and floury leaf spots of beans. Singh, B. M.; Sharma, Y. R. (Himachal Pradesh Univ., Palampur, India). Indian J. Mycol. Plant Pathol., 6(2), 148-51 (English) 1976. CODEN: IJMPAK. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) Of 9 fungicides tested as spray applications (2, 3, and 4 applications at 15-day intervals) for control of angular and floury leaf spot (caused by Isariopsis griseola and Ramularia phaseoli, resp.) on bean, Benlate (I) [17804-35-2] (0.025%) was the most effective, followed by Cercobin [23564-06-9] (0.2%). Spray cycles of 3 or 4 wk using I did not give satisfactory protection.
