Lethbridge Herald, The (Newspaper) - July 25, 1972, Lethbridge, Alberta -Tuesday, July 25, 1972 THE LEIHBRIDGE HERALD 3 wireworm By C. E. LILLY Lclhbridgc Research Station Wireworms, the larvae of "click may cause ex- tensive damage to potato crops IUIUGATIONIST Jay PurncII is (he newly appoint- ed director of the Alberta de- partment of agriculture's irri-. gation division with head- quarters In LelLbriilge. The division is responsible for all agricultural aspects of irriga- tion within the province. It was created as a result of the transfer of certain areas of responsibility from the dc- fparlmcnt of the environment to the department of agricul- ture. It also includes the irri- gation council and the irriga- tion secretariat. Mr. Purncll. brother of dep- uty agriculture minister Dr. Glen Purncll, has a VTidc background in water en- gineering. Ho worked for the city of Calgary and for four years was employed as assis- tant and district engineer with the British Columbia water authority. by tunnelling into tlie develop- ing tubers or by defacing their surfaces with shallow feeding scars. Such tubers are unsight-' ly and may be unmarketable, Wireworms probably can be found in every cultivated field but large populations are most commonly found in light to med- ium soils and in new breaking. Even when their numbers arc high they are difficult to find unless they are feeding on sus- ceptible crops. A crop-damage history of each field will assist the grower to decide the nec- essity of applying insecticide when planting potatoes in any particular field. One soil application ot insec- ticide at the recommended rate usually reduces the wireworm population significantly for sev- eral years as there is limited movement between fields. The population is seldom, if ever, completely destroyed, however, and will build up to economic levels again In time. Insecticide trials have been carried out at the Lelhbridge Research Station for several years. The degree of protec- tion given by named com- pounds such as Dyfonate, Das- anit, Furadan, chlordane, dia- zinon, and several numbered experimental compounds has been determined by assessing the percentage by weight oE marketable tubers free of wireworm damage. Tire results of these experi- ments have indicated that Dy- fonate, broadcast at five pounds of r.clive material per acre or at two pounds In-furrow per acre, gave better than 99 per cent protection. Dasanit at two pounds in-furrow per acre gave more than 95 per cent protec- tion.

Phone 328-6977 New quotas encouraging says Alberta Wheat Pool wireworms in potatoes since aldrin, dieldrin, and heptachlor were banned, gave 03 to 90 per cent control. Furadan also gave variable protection ranging from 71 to 91 per cent. The only current registered treatments recommended by the Western Committee on Crop Protection are Dyfonate broad- cast at five pounds of active material per acre (50 pounds of 10 G formulation) or cHordane broadcast at 10 pounds of ac- tive material per acre (40 pounds of 25 G The insecticide should be broad- cast just before planting and immediately worked into the top four to six inches. Do not apply chlordane more than once every four years and do not grow sugar beets or other root crops in soil treated with this insecticide. The announcement by t h e Canadian Wheat Board of open- ing quotas for the new crop year indicates a number of sat- isfying tilings: Canadian grain system is up-to-date and aware of its opportunities; producers who form the basic segment of the system are given an opportunity through the announcement to play a fdl part; is room in country and terminal facilities for the kinds of grain needed to satisfy Canada's overseas customers; 1972 late summer and harvest season promises to be one of the busiest half years grain shipping in the history of the CWB. With 13 ships currently load- ing at Vancouver and six more expected to arrive during the first week of the new crop year, there is clear need for heavy shipment to west coast porls on a continuing basis. Settlement of the port strike in Japan has encouraged hope that the early winter shipping season can be used to move the largest possible volume of grain, as it is in Canada's in- terest to have the maximum number of ships from customer countries use Canadian facili- ties to greatest advantage be- tween now and Christmas. The Alberta Wheat Pool says it is confident Alberta produc- ers will support the efforts the CWB to use the grain mar- keting system to best advan- tage by maintaining deliveries until and during the harvest season. Quotas announced for ths new crop year include a two- bushel quota on wheat and a five-bushel quota on barley and oats, plus an additional two- bushel quota on wheat in somo Alberta and Saskatchewan shipping blocks.
