- Survey of Corn Diseases and Pests in Ontario and Québec in 2005
From August 23 to September 13, 2005 a corn pest survey was conducted in Ontario and Québec. As usual, the emphasis of this years survey was to determine the distribution and severity of diseases and insects. In addition, scouting for any newer pests in Canada was conducted.
- Help with Plant Identification
There are over 5,000 species of plants that grow wild on the Canadian landscape,
and many of them are difficult to identify. There is need for accurate plant
identification, particularly in relation to environmental protection, alien
invaders, and commercial collecting of wild plants. However, few people concerned
with biodiversity issues know what aids are available to assist in identification.
This new guide to resources for identification
of Canadian plants outlines the most current sources of reliable information.

- Screening Corn for Resistance to Common Diseases in Canada
The publication 'Screening
Corn for Resistance to Common Diseases in Canada' describes field
screening techniques for common diseases of the ear (gibberella ear
rot, fusarium ear rot, common smut) stalk (gibberella, fusarium and
anthracnose stalk rot) and leaves (eyespot, common rust and Northern
corn leaf blight) of corn grown in Canada. Details of inoculum production,
inoculation technique and evaluation of resistance are given for each
disease. As well, a general summary on nursery designs, isolation of
pathogens, pathogenicity tests, safe handling of inoculum and infected
plant material, and statistical analyses and data interpretation is
given.

2002. RUSLEFAC - Revised Universal Soil
Loss Equation for Application in Canada: A Handbook for Estimating
Soil Loss from Water Erosion in Canada. ECORC Contribution No. 02-92.
Soil erosion remains a sizable problem for Canadian agriculture,
in terms of both cost and degradation of the natural productive capability
of the soil. Improved predictive models are needed to estimate the
nature and extent of the problem. The handbook describes methods
to estimate soil loss from water erosion and predict soil erosion rates
under Canadian conditions.

Inventory of
Canadian Agricultural Weeds
This publication is an inventory of and reference guide for Canadian
weeds, primarily those of importance to agriculture. It includes plants
that are weeds in a variety of agricultural contexts (field crops,
rangelands, commodity trade, sylviculture, etc.). All common species
are covered as well as uncommon ones that are actually or potentially
important for biological or social reasons.
