Bulletin No 3768 - Submitting Plants For Disease Identification, M D. Marcley

Bulletins - 3000 - 3999

THERE are several important points to remember when submitting plant material for disease identification by the Department of Agriculture's Plant Pathology Branch.

Firstly it is very important to collect a suitable sample because it is very difficult to determine the cause of a plant disease by looking at a completely dead plant. The sample should include the entire plant (before it is completely dead) including roots and soil. Then all the effects of the disease can be seen. For example leaf yellowing, dead areas of the stem, collar rot, root rot, eelworm damage, and disease of the water and food …

A Study Of Puccinia Graminis And Cronartium Ribicola, Duane W. Hughes

Graduate Student Research Papers

It was the purpose of this study (1) to review the literary history of rusts in the United States and in the Northwest in particular, ( 2) to learn where rusts generally are found geographically, (3) to gain further information regarding the etiology of wheat rust (Puccinia graminis tritici), of white pine blister rust (Cronartium ribicola) and to become enlightened on other rusts, (4) to learn ways of controlling the two rusts, black stem rust of wheat and white pine blister rust, and to gain an appreciation of the economic importance of rust prevention.

Bulletin 119 - Take-All Of Wheat And Similar Diseases Of Cereals, W. M. Carne, J. G.C. Campbell

Bulletins 1 - 2999

This important disease, known also as Footrot, Blackleg, and Whiteheads, affects wheat principally, but also occurs on barley, rye, and certain grasses. In a very few instances it has been known to attack oats, but this is so rare that oats may be regarded for practical purposes as free from attack. Of the grasses attacked the most important, from a farming point of view in Western Australia, are Bailey Grass (Hordeum murinum), Silver Grass (Festuca bromoides and F. myuros), and the so-called Spear grasses (Bromus spp.). These annual grasses are very common in the wheat belt.

Bulletin 121 - Mildew, Septoria, Leaf Spots And Similar Diseases Of Cereals, W. M. Carne, J. G. C. Campbell

Bulletins 1 - 2999

Mildew attacks all the cereals as well as many grasses. but as in black stem rust the fungus has developed specialised races, one attacking wheat, another barley, another rye and so on, so that the form attacking wheat will not attack oats, etc
