Application Information
How to Apply
:
Apply with ground equipment only. Do not apply by air. Note: Do not use galvanized steel or unlined
steel tanks as a combustible gas may be formed.
Water volume
: 40
L/acre.
Application Tips
Ensure that the crop has not advanced beyond the recommended leaf stage for application. Treat crops during warm
weather when weeds are actively growing. Best results are obtained when Canada thistle is actively growing and soil
moisture is adequate for rapid growth. Do not treat weeds under poor growing conditions. Reduced results may occur
when treating weeds heavily covered with dust. Reduced results may occur if water-containing soil is used, such as
water from ponds and unlined ditches.
How it Works
Eclipse tank mix is readily absorbed by foliage and roots. Eclipse A is a systemic, hormone-type herbicide absorbed
by leaf, stem surfaces and roots and translocated upwards and downward. Eclipse B is a non-selective, systemic
herbicide that moves from the foliage into the roots and kills the entire plant. Maximum efficacy results from foliar
application to young, actively growing plants.
Expected Results
Under good growing conditions, wilting and yellowing of annuals occurs within 2 - 4 days. Herbicide symptoms on
affected annual and perennial weeds may also include swollen growing points and roots, cupping of leaves, twisted
and distorted stems and leaves. Cool or cloudy weather may slow activity. Affected weeds turn yellow before turning
brown as they die. Death of weeds may not occur until 14 - 21 days after application. Browning of above ground
growth and deterioration of roots occurs.
Restrictions
Rainfall
:
Do not apply if rainfall is forecast for the time of application.
Grazing
:
Allow 3 to 5 days before grazing treated areas.
Re-cropping
:
Fields previously treated with Eclipse III tank mix can be seeded the following year to wheat, oats,
barley, rye (not underseeded with legumes, clover or alfalfa), forage grasses, flax, canola, mustard, field peas, or they
can be summerfallowed. Seed only those crops listed above in the year following treatment. Do not seed to field peas
for at least 10 months following treatment. Very dry soil conditions following application can result in a risk of injury
to field peas grown in rotation. If severe drought conditions are experienced during the months of June to August
inclusive in the year of application, delay seeding field peas an additional 12 months (total 22 months following
application).
Manure and Straw
:
Residues of the herbicide tank mix occurring in the straw may be harmful to susceptible plants.
Do not use straw or crop residue from treated crops for composting or mulching susceptible broadleaved crops. If
the straw or crop residue is used for animal bedding or feed, return the manure to fields to be planted to clopyralid
tolerant crops such as wheat, barley, oats, rye, forage grasses, canola or flax. Do not grow susceptible crops such
as peas, beans, lentils, potatoes, sunflowers or other sensitive crops on land which has been mulched with straw
containing clopyralid residues within the last 12 months. such as peas, lentils, potatoes, and sunflower.
Environmental Precautions
Avoid contamination of non-target land, water or irrigation ditches. Do not use Eclipse III tank mix where it can enter
water bodies.
