Lethbridge Herald, The (Newspaper) - September 4, 1970, Lethbridge, Alberta Cover Crop Colors DR. T. G. ATKINSON, Plant Pathologist The apperance of unusual colors in cereal coyer crops this fall could indicate the presence of a virus disease that can lower both the yield and quality of the forage pro- duced. "Barley yellow dwarf as the name implies, turns the leaves of barley a distinctive golden yellow. Name notwith- standing, the same virus causes an equally striking and characteristic "red leaf" symp- ton in oak. In both crops the symptons first appear on the older living leaves, which change color progressively from the tip downards, usually beginning along the leaf mar- gins. Fall frosts sometimes cause color changes that can be mis- taken for those caused by the disease, but in oats and barley the virus-induced discolorations are usually quite distinctive. In contrast, virus-infected wheat Warning On Rats Farmers along Alberta's eastern border are urged to prevent rats from migrating in- to this province by keeping plenty of warfarin dry bait around their buildings and feed stacks between now and the first snow fall. Dale Alsager, animal pest specialist with the Alberta plant industry division, points out that there is always an in- crease of rat migration at tin's time of year, and that it has been the vigilance of farmers and pest control officers along this border that has kept Al- berta rat free for 18 consecu- tive years. Tile Drains Plastic drain tiles are gaining in popularity across Canada. Fanners seem to like the new material because it is light, easy to handle and install and will likely present fewer maintenance problems. may show no symptons or at most, an inconspicuous yellow- ing. The disease-causing virus is transmitted from plant to plant and carried from field to field by aphids that feed on cereals and grasses. Therefore, the oc- currence and Ihe intensity of the disease depends on those factors that influence the mi- gration- and build-up of popula- tions of the aphids. Similarly, the severity of the damage caused by the virus depends on how young ths plants are when they become infected. Both these factors are more likely to favor the development of "bar- ley yellow dwarf" on cover crops than on crops gorwh for grain. In southern Alberta, oat or barley- cover crops for fal pasture afe sown about mid- July. Since large populations of aphids seldom appear before late summer, it is the cover crops rather than the earlier- sown grain crops that are ex- posed to the disease at an early, highly susceptible stage of development. Fortunately, ir recent years, predators and parasites have been keeping the disease-carrying aphids in check. Nevertheless, scientists at the Lethbridge Research Station believe that this insect- transmitted virus disease must be recognized as a potential hazard in the production of fall pasture. Barley yellow dwarf virus has long been known to drastic- ally lower grain yields of in- fected crops but little was known of its effect on the for- age produced by cereal cover crops. Preliminary studies at the Lethbridge Research Sta- tion show that the- disease low- ers both yield and quality of the forage. The dry matter forage yield of Victory oats in- fected in the seedling stage and harvested "in the boot" was reduced 25 per cent. The pro- tein content of the diseased forage was also reduced so that the total yield of protein was only half that of forage from healthy oats. In more recent experiments, Betzes barley, which was more heavily in- fested with populations of the virus-carrying aphids, lost 60 per cent of its forage dry weight. The protein content of the diseased barley forage has not yet been determined but it would be surprising if its qual- ity was also not lowered.

Work On Irrigation Systems Reveals Additional Problems By N. S. THOMSON Regional Director, Water Resources Division, Lethbridge Two years experience in actu- al construction of so-called irri- gation rehabilitation works has resulted in more unanswered questions and has painted the way for future requirements. After five years of study be- ginning in 1962 the "Alberta Irrigation Policy Recommen- dations" were published in Jan- uary 1967. Discussion and fur- ther study with interested bod- ies led to a new Irrigation Act passed by legislature in May 1968. This Act brought the irri- gation districts under one legis- lative Act leading to the diffi- cult task of achieving some consistency in their operation. After much discussion and some heated debate the Act was amended in 1969 and again in 1970 resulting in an Act which satisfies most of the dis- tricts in most of their opera- tions. The prime consideration of the recommendations however, was not only a new Act but a financial program to rehabili- tate the irrigation districts dis- tribution works. The recommendations called for a joint financial undertak- ing by federal government, provincial government, munici- pal government and the irriga- tion districts. Negotiations to date have been painfully slow and apparently federal contri- bution will be contingent upon more negotiation and mutually agreeable discussion. In order that (lie program could begin the provincial government pro- vided in 1969 and in 1970 plus the en- gineering services of Uie water resources division.

The agreed unanimously and the grant-was made. The unanswered question is "Can the districts. rehabilitate feasibly on this small amourr of money granted Future requirements seem to be a larger more stable financia. program. Water resources' experience in engineering this program in- dicates that three essential re- quirements must be met to in- sure a rehabilitation program that will be a lasting monumen to irrigation agriculture. Individual water user in- volvement; 0 A general plan of com plete rehabilitation; O A financial undertaking that allows fulfillment of the general plan over a scheduled period 01 time. In our particular political cli- mate the involvement of the individual water user is 01 prime concern. He must know what he needs to serve his pur- pose, what his alternativts are and what they will cost to builc and operate. We are dedicated to this educational purpose as a first step in the rehabilitation program. To achieve rehabilitation the job must be planned and sched- uled to avoid a crisis approach to the A general plan will provide the basis for a sched- uled program of rebuilding and figures for financial negotia- tions. The general plans for aU irrigation districts are sched- uled for completion over a per- iod of the next two years.

One of the factors for achieving a proper application of water by sprinkler is to have the difforence In pressure between the first and last sprinkler head on the lateral line no grealer than 20% of the pressure at the head of the lateral which a usually about 45 p.s.i. (pounds square This makes for a more uniform sprinkler discharge along the entire length of lateral. Example First sprinkler 45 p.s.i. x 20% equals 9 p.s.l., 45 p.s.i. less 9 p.s.i. equals 34 p.s.i. en las! sprinkler The time required per set, to apply water on well established crops such as sugar beets and alfalfa would about 8 hour, on Medium soils and 11 hours on Heavy (Fine) soils, The financial undertaking must be a long-term commit, ment to provide for proper scheduled planning. Despite ec- onomic studies the impetus for the financial program must come from the individual water user through his district board and thence to the provincial government. The statement that the primary producer only receives 10 per cent of the bene- fits of irrigation does not auto- matically assure him that his costs will only be 10 per cent. History dictates that without more involvement and never ending urging that he will be ths victim of all the expenses. The cause must be sold and sold hard. I regret that I end my tenure as regional director of water resources on such a pessimistic note. I firmly believe however that the battle can be won with encouraging results and I will endeavor to further the cause through my new office of direc- tor of program development, which houses the irrigation secretariat. Mustard Harvest Instructions Mustard growers are strong- ly advised to keep in close con- tact with their contracting com- pany regarding recommended harvesting practices. Following are a few general guidelines from the Alberta de- partment of agriculture's cer real and oil seed crops special- ist Sherman Yelland. Mustard crops that have ripened evenly and are free of green weeds should be straight combined. It is particularly im- portant to straight combine yel- low mustard if at all possible, because the pods tend to break off the stems easily and be- cause the swaths of this variety are very prone to blowing. If it is not possible to straight combine a mustard crop, it should be swatted when 20 to 25 per cent of the seeds have turned brown and the green seeds are hard when pressed between the finger and thumb. As with rapeseed, the stubble should be left as high as pos- sible to prevent the swaths from blowing and to keep them off the ground. Cows Tested More than cows were tested and their milk produc- tion certified in 1969 under the federal Record of Performance (ROP) program for purebred dairy cattle, reports the live- stock division, Canada depart- ment of agriculture. Ths program is to establish production credentials for all purebred dairy cows en- tered for testing so that the re- sulting information may pro- vide a solid basis for effective breeding programs.
