A field study was conducted in 1973 and 1974 to determine optimum
timing of metribuzin (4-amino-6-tert-butyl-3(methylthio) as -
tria.zine-5(4H)one) on winter wheat (Triticum aestivum L. 'Hyslop')
for control of Italian ryegrass (Lolium multiflorum Lam. ). Herbicide
treatments were applied at 5 different stages of growth of winter wheat.

Previous field research with terbacil (3-tert-butyl-5-chloro-
6-methyluracil) has shown that early fall applications to dry soil
performed better than did late fall or early winter applications to
wet soil. Field and greenhouse studies were conducted to determine
the effect of soil moisture content at time of application and the
effect...
Lateral diffusion of S-ethyl N-ethylthiocyclohexanecarbamate
(cycloate)¹ is essential for satisfactory weed control with injection
type incorporation in sugar beet (Beta vulgaris Linn.) production.
Previous field experience with injection incorporation has indicated
that sufficient lateral diffusion for satisfactory weed control has not
occurred under all field conditions. Researchers who have been...
Studies were conducted to determine the nature of the interaction
between atrazine (2-chloro-4-ethylamino-6-isopropylaminos-
triazine) and magnesium on tomatoes. This interaction was
studied under two light regimes: continuous light and a 12-hour
photoperiod. Tomato plants were grown in sand cultures at three
levels of magnesium fertilization. Four weeks after planting,
atrazine...
