Info

- Within this coming year a key for the iden ification of the important grasses of the Northeast by their vegetative characteristics will be available. This key wi 1 be simplified as much as possible but of necessity manyf the separations will be based on differences as seen th~o g~ a lO-X magnifier. 1 trust that these magnified color ransparencies you have just seen will help you "see" what you "look at" and successfully. use the key. -
5. FACTORSINFLUEUCINGTHE PERFORFANCE OF GRANULAR HERBICIDES R. D. Sweet Deparlment of Vegetable Crops, Cornell University, It aca, N. Y. In the last year or two numerous investigators have st died dry granular carriers for herbicides. Previous to this only a few had s riously investigated their possibilities. Amongstfa;rmers J the interest in granulars stems prim 'ly from their dislike for hauling water or for running the sprayer to som location away fran the field in order to refill. The water problem is ac te even in regions where water is relatively plentiful. Of considerable concern to weed 'Workers is the perform ce of granular formulations as compared to that of the conventional formul tions. Research to date on performance is wholly inadequate to permit many onclusions or generali;a.tions. Some of the factors influeneing performan e are as follows: 1. The chemical itself has an important bearing on re lts. Certain compounds such as EFTCalmost always give better results on a granule. On the other hand Atrazine at lower rates performs better as a wettable powder. CDD::may perform better or worse on a granule depending on actors at present unknown .J, 2. The nature of the carrier may play an important ro is known regarding the several types of carriers, particle on the carrier, best methodo£' formulating, etc. e, but little ize, percentage 3. The influence of environment and soil on granular canpared to conventional formulation, is sufficiently well 4. Even distribution of the herbicide at the desired ate is as neces sary with granulars as with liquids. Presently available e uipment does not lend ;itself to ea5Y, accurate application. However, equipm nt manuf'acturers are aware of the needs, and presumably in the near f'uture 11 have machines a:vai.lable to do the job well ..
