Herbicides
rainfall of 1.5 cm or more when wild oats are emerging can cause post-emergent die-back of a high percentage of
wild oat plants.
Crop
:
Wheat seeded into the treatment zone under very dry soil conditions may be thinned and delayed when
germinating and emerging just prior to a heavy rainfall. Wheat must be seeded at least 1.5 cm below the treated
layer of soil (e.g. 5 - 7.5 cm). Some wheat thinning may be noted on eroded knolls. Poor results may be expected
if incomplete incorporation due to wet, cloddy soil or heavy trash, incorporation delayed, very dry soil conditions
in spring or prolonged cool soil temperatures at time of germination. Ridges left by seeding may disrupt the treated
layer and allow escapes.
Restrictions
Rainfall
:
Moisture is required for activation. Rainfall of at least 1.5 cm within 2 weeks of application in the spring is
required to ensure maximum performance.
Grazing restrictions
:
Treated underseeded legumes cannot be harvested for green feed, silage or hay in year of
seeding. Do not graze the treated crop or cut for hay; there are not sufficient data to support such use.
Re-cropping
:
Oats should not be seeded into soil treated with Extra Strength Avadex BW/MicroActiv in the
previous year.
Environmental Precautions
Do not apply directly to water or to areas where surface water is present.
Runoff
-
to reduce runoff from treated areas into aquatic habitats, consider the characteristics and conditions of the
site before treatment. Site characteristics and conditions that may lead to runoff include, but are not limited to, heavy
rainfall, moderate to steep slope, bare soil, poorly draining soil (e.g. soils that are compacted or fine textured such
as clay). Avoid application when heavy rain is forecast. Contamination of aquatic areas as a result of runoff may be
reduced by including a vegetative strip between the treated area and the edge of the water body.
Leaching
-
the use of this chemical may result in contamination of groundwater particularly in areas where soils are
permeable (e.g. sandy soil) and/or the depth to the water table is shallow.
Volatilization
-
the active ingredient contained in this product is known to volatilize. Effort should be made to reduce
the volatilization such as the following: (1) incorporation into the soil concurrently with application, (2) application
should occur when soil temperatures are less than 4°C or less.
Toxicity
Low acute mammalian toxicity. Acute oral LD
50
(
rats) = 1,675 - 2,165 mg/kg. May cause slight eye irritation. Slightly
toxic to fish. Non-toxic to birds.
Storage
Store above 0°C. If frozen, warm to 22°C and agitate to redissolve crystals.
