154. Alberta Agriculture, Crop Protection Branch. 1989. Guide to crop protection in Alberta. 1988. Part II - Non-chemical control of weeds, insects, diseases for maximum economic yield.. Print Media Branch, Alberta Agriculture, 7000 - 113 St.,.
Alberta Agriculture's non-chemical guide to crop protection contains 28 pages of general advice on how to control weeds, insects, and disease in crops without chemical pesticides. This includes crop rotation, sanitation, crop competition, physical control, biocontrol, and field scouting. The rest of the book looks at specific pests and considers their life cycles, emergence, reproduction, management strategies, and control. Where available, tables of economic thresholds are included. This is an excellent reference for assessing potential alternatives to chemical pesticides for a large number of pests.

New sprayer technology using high air velocity and/or electrostatic charge has the potential to deliver pesticides more effectively to the target and reduce their use by 25-50%. These sprayers can often be used under much windier conditions than conventional units with minimal risk of drift. The electrostatic unit gives droplets a negative charge, and thus they are attracted and attached to the positively charged plants. Pesticide half-life may also be increased by the charge.

This technical volume highlights the biochemistry of a number of potential compounds derived from microbes, plants, or insects, that may have a role as a pesticide or plant growth regulator. Topics include screening for microbial herbicides, the role of glucosinolates, compounds from sea organisms, and chitin/chitosan products.
