On a provincial level, the worm damaged only I per L-nil of the total acres in 1971 bill many areas were liard hit, some by the location and de- gree of infestation, some by the circumstances and -some by lac'k of timely assis- tance. .lake ncmjkc-1 and 1'is wife Pearl farm in the Nipawin area of northern Saskatche- wan.

S. llorricks, of the Lelhbridgc Research Sta- tion, discovered that Ihc resi- due of rapeseed plants depress- ed Ihe growth and yield of! crops grown on the same land the following year. This reduc- tion could not be attributed to a disease or nutritional defi- ciency. 11 soon indicalcd that an unidentified substance from the rapeseed plants remained in Ihe soil and was responsible for the inhibilion in growth. Since many rapcsccd growers seed a cereal crop following the rapeseed. Ihe search be- gan for a solution to the prob- lem. Spreading Ihe crop resi- due as evenly as possible over Ihe field reduced losses. How- ever, before a more adequate answer can be found, we will have lo isolate and identify the casual substance. AI the Lcthbridgc Research Station we have made alcohol, and ether extracts of j dried rapc.-.eed leaves and i stems. Tbrv inhibited Ihe growth of gcrmin.ntinR cereal seeds. We. therefore, now have the subslanfc in a form that can be studied and a simple biological mc'.liod to measure its presence. The active ingre- dient must now be separated i from the many other complex' chemical compounds in the ex tract to learn its chemical and physical properties and thus identify it. After the organic mat- ter from Ihe extract burn- ed away the remaining ash still showed sonic growth-depress- ing activity. Most of it, how-, ever, was present in the burn- able organic matter. Freezing! or boiling the cxtrcct did not destroy its activity. These properties are useful because. they allow us to store the ma- j lerial and to perform the many laboratory tests required to identify it. By ion exchange chromato- grajihy we have already learn- ed a good deal about Ihe prop- erties of the inhibitor. Other complex analytical techniques will supply further information. As these data accumulate they will provide us with a complete knowledge of the chemical na- ture of the compound and fi- nally ils identity. Plant breed- ers will then be able to deter- mine whether their present breeding programs will elim- inale the inhibitor from new. varieties, just as the erucic. acid content was reduced. Oth- er programs may have to be devised. Teamwork of many agricultural scientists may be required. We are confident that the problem can be solved and that it will be possible lo grow cereals following a rapeseed crop and obtain maximum ields. end of i UK. peas and Shi' K; J.I oiild eal only certain leaving bare pa'cho- m and in'. farl through a' wheat in-Ill. c-.: II." v.eeds.!
