Fungicidal dusts for the control of bunt / By W. W. (William Wylie) Mackie and Fred N. Briggs. Abstract. Mode of access: Internet Topics: Wheat, Bunt (Disease of wheat) Publisher: Berkeley, Cal. Tests at the Federal seed-testing station, Mont Calme, Lausanne, with fungicides intended for the control of wheat bunt (Tilletia tritici) [T. caries: R.A.M., 26, p. 11; 28, p. ] were carried out on the variety MC B, both healthy and infected seed of which gave per cent. germination. Only per cent. copper carbonate and per cent. zymá 3 dusts were completely non Author: J. Rapin. Much of the early history of this pesticide is lost, but its pesticidal properties were known by the ancient Greeks as early as B.C. FORSYTH () first recorded the recommendation of sulfur for the control of diseases. His recommendation for the control of powdery mildew on fruit trees was a concoction of quicklime, sulfur, Cited by: strobilurin fungicide for control of these diseases, it is probably not necessary to purchase another. (ii) Since all fungicides in a chemical group control the same diseases, it does not make sense to tank-mix fungicides that represent a common chemical group in order to expand the scope of control.

Chemical methods – study of different groups of fungicides. Methods of application of fungicides Fungicides – definition. The word „fungicide‟ originated from two latin words, viz., „fungus‟ and „caedo‟. The word „caedo‟ means „to kill.‟ Thus the fungicide is any agency/chemical which has the ability to kill the Size: KB.

The breakdown of potato planting material is a serious problem in southern Queensland, particularly where cut seedpieces are used. Some growers use captan (50 g kg-1) or zineb (40 to g kg-1) dusts to reduce losses, but the values of these treatments have not been accurately assessed. A number of chemicals were compared with a standard zineb (80 g kg-1) treatment Cited by: 1. to insoluble or poorly water soluble dusts of low toxicity. Summary This paper was compiled to give guidance on the assessment, evaluation and control of occupational exposure to dusts not otherwise specified (Dust NOS) with an emphasis on recommending a health‐based occupational exposure limit (OEL).File Size: 1MB.

Trials for the control of white mould of beans (Sclerotinia sclerotioruni) indicate that on the dusted plots Zerlate and Flotox reduced infections by comparison with controls, and on sprayed plots Zerlate plus Sulforon was very much superior to the other fungicides by: 4.
