Efficacy of imazaquin on various weed species
1991
Risley, M.A. | Oliver, L.R.
Field and laboratory investigations were conducted from 1983 through 1985 to evaluate morphological and environmental influences on the performance of imazaquin on 26 weed species common to the Mississippi Delta. Imazaquin applied preplant incorporated or preemergence at 140 g ai ha-1 controlled 16 species but controlled only five species at 140 g ha-1 foliar applied. Contour graphs accurately predicted imazaquin postemergence rates necessary to control a given weed species at a given time after emergence. Imazaquin applied preemergence with a sequential postemergence application controlled entireleaf morningglory and sicklepod better than a single soil application. Imazaquin at 140 g ha-1 applied preemergence required at least 50 mm of supplemental water following application to control sicklepod and was more phytotoxic to sicklepod grown at 25/10 C day/night temperatures than those grown at 32/22 C.

The effect of dilution water quality on herbicide efficacy Full text

Holm, F.A. | Henry, J.L.
Non-Peer Reviewed | The antagonistic effect of Ca2+ and Mg2+ ions on the efficacy of glyphosate (Roundup) has been well documented for some time but there is relatively little information available on the effect of other ions on glyphosate or other herbicides. Field trials were conducted at Saskatoon in 1989 and 1990 to determine the effect of dilution water ion content on the efficacy of several herbicides. Water sources examined were: Saskatoon (surface, fresh, low mineralization), Goodale (artesian well, hard, high Ca2+ and Mg2+), Zelma (well, hard, high Fe3+), Outlook (well, soft, high Na+), Unity (well, soft, medium HCO3-), Maple Creek (well, soft, high HCO3-) Recommended and less than recommended rates of selected herbicides were applied in four replicate field trials using standard flat fan nozzles that delivered 130 L/ha (1989) or 110 L/ha (1990) of spray mixture. Herbicide X water combinations that have resulted in reduced weed control as compared to Saskatoon water as the check are: glyphosate (Roundup) X Goodale or Zelma, sethoxydim (Poast) X Unity or Maple Creek, clethodim (Select) X Unity or Maple Creek, 2,4-D amine X Goodale, Outlook or Unity. Imazamethabenz (Assert) was not affected initially but plants treated with water from Unity or Maple Creek recovered more rapidly than those treated with Saskatoon water. Fenoxaprop-ethyl (Excel), 2,4-D ester, and glufosinate ammonium (Ignite, Harvest) were not affected by water source.

Efficacy of albendazole (Adamas) on treatment of Fascioliasis in cattle
1991
Supol Luengyosluechakul (Chulalongkorn Univ., Bangkok (Thailand). Faculty of Veterinary Science. Dept. of Veterinary Medicine)
One week after a treatment with ivermectin injection, albendazole suspension (Adamas) of 11.25 % was orally retreated to a herd of cattle, 68 heads, with history of cachexia, chronic diarrhea and jaundice. Coprological test revealed severe infection by Fasciola spp. Up to end of the first two months, worm egg disappeared together with a rash improvement of total herd. No more animal died from infection. The drug was proved to be safe even for pregnant cow and unsound animal.
