Insect Growth Regulator for the control of larval stages of Colorado potato beetle on potatoes in Ontario, Quebec and Atlantic Canada ONLY.
"One Water Soluble Bag” contains 908 grams of GOVERNOR 75WP.
Do not allow the water soluble bags to become wet prior to use. Do not handle individual water soluble bags with bare hands or wet gloves as this may cause breakage. (as the water soluble bags will begin to dissolve immediately). Store above freezing in a dry location. Prolonged storage at temperatures below 0 degrees Celsius may cause the water soluble bag to become brittle.

STORE IN A DRY PLACE.

DECONTAMINATION AND DISPOSAL
For information on disposal of unused, unwanted product, contact the manufacturer or the provincial regulatory agency. Contact the manufacturer and the provincial regulatory agency in case of a spill, and for clean up of spills.

CONTAINER DISPOSAL:
1. Empty bag thoroughly into spray tank.
2. Make the empty bag unsuitable for further use.
3. Dispose of the bag in accordance with provincial requirements.

GENERAL INFORMATION
GOVERNOR 75WP is an insect growth regulator (IGR), active against early larval stages of the Colorado potato beetle. When applied to first generation Colorado potato beetle larvae according to the directions given below, GOVERNOR 75WP will provide control by inhibiting the development of larval stages. GOVERNOR 75WP is active on Colorado potato beetle larvae that are resistant to currently available chemistry (e.g. synthetic pyrethroid or organophosphate insecticides).
Life Cycle of the Colorado Potato Beetle:
The Colorado potato beetle overwinters as an adult in the soil, emerging in the spring to mate and lay eggs on the undersides of potato leaves. These eggs hatch to first instar larvae over a period of up to three weeks. Larvae of the Colorado potato beetle pass through four instar stages, each instar larger and causing more defoliation than the previous. Fourth instar larvae drop to the soil to pupate, later emerging as an adult of the second generation.
Integrated Pest Management:
Under conditions in which the early adults emerge in a strong flush, the use of cultural, physical, or chemical control methods may be used to reduce their numbers and, in turn, reduce the number of eggs laid on the potatoes.
Subsequent control measures directed against larval stages of the Colorado potato beetle form the basis of most management programs. This is effectively accomplished with TWO PROPERLY TIMED applications of GOVERNOR 75WP, targeted against the early larval stages of the first generation of the season. Proper application timing can be achieved by regular and frequent crop scouting. Please refer to the Directions For Use section of the label for specific application instructions. The use of GOVERNOR 75WP will give control of the Colorado potato beetle through the first generation and result in a significant reduction in the population of any subsequent generations.
GOVERNOR 75 WP has excellent contact and feeding “systemic” action against the 1st and 2nd instar larvae of Colorado potato beetle. The larvae stop feeding immediately after the uptake of GOVERNOR 75 WP and do not develop any further.

DIRECTIONS FOR USE
INSECT GROWTH REGULATOR FOR THE CONTROL OF LARVAL STAGES OF COLORADO POTATO BEETLE ON POTATOES IN ONTARIO, QUEBEC AND ATLANTIC CANADA ONLY
Do not apply by aircraft. Do not apply through any type of irrigation system.
RATE OF APPLICATION:
First Application:
Apply at rate of 373 grams of GOVERNOR 75WP in a minimum of 110 L of water per hectare as a foliar spray. One water soluble bag treats 2.5 hectares (6 acres).
Second Application:
Apply at a rate of 186 grams of GOVERNOR 75WP in a minimum of 110L of water per hectare as a foliar spray. One water soluble bag treats 5 hectares (12 acres).
TIMING OF APPLICATION:
Target TWO applications of GOVERNOR 75WP against small Colorado potato beetle larvae of the first generation of the season. Frequent field scouting is important to identify the development stages of Colorado potato beetle and the larval population levels.
First Application:
Apply GOVERNOR 75WP when 30% of eggs of the first generation have hatched and small larvae are observed.
A suggested scouting technique is as follows:
Locate and mark 20 (or more) plants with egg masses
Monitor the egg masses on the marked plants daily
When 6 of 20 egg masses have hatched (or 30% of the number used), apply GOVERNOR 75WP.
In warm conditions (>24 C) eggs will hatch quickly and the percent of egg masses hatched can change significantly in one day. In these conditions, it is recommended that 10% egg hatch be used as the timing for the first application.
Second Application:
The second application is necessary to provide lasting control through the first generation of Colorado potato beetle. Apply GOVERNOR 75WP 6-10 days after the first application. Use the shorter re-spray interval (6-7 days) during periods of rapid larval development (>24 C).
Do not apply within 14 days of harvest.
Potato fields treated with Governor 75WP may only be rotated with the following crops: head lettuce, leaf lettuce, celery, spinach, tomatoes, peppers, melons, cucumbers, hay, wheat, barley or oats.
The following plantback intervals must be observed when planting rotational crops after an application of Governor 75WP on potatoes:
Head lettuce, leaf lettuce, celery, spinach, tomatoes, peppers, cucumbers, melons: 1 day
Hay, wheat, barley, oats: 300 days
Cyromazine has the potential to persist in soil and to carry-over into the subsequent year. Use of Governor 75WP on the same field in consecutive years should be avoided.
This product demonstrates the properties and characteristics associated with chemicals detected in ground water. The use of Governor 75WP in areas where soils are permeable, particularly where the water table is shallow, may result in ground water contamination. Do not apply within 15 metres of well-heads or aquatic systems, including marshes, ponds, ditches, streams, rivers and lakes. Do not mix, load or clean spray equipment within 30 metres of well-heads or aquatic systems.

MIXING INSTRUCTIONS
GOVERNOR 75WP is a wettable powder formulation to be mixed with water and applied as a spray. Be sure sprayer is clean; if it is contaminated with any material, crop injury or sprayer clogging may result.
Mixing Steps:
1) Fill the tank 1/4 to 1/2 full with clean water and start agitation.
2) Add the correct amount of product.
3) Complete filling tank with water, maintaining sufficient agitation at all times.
4) Do not leave spray mixtures in the tank without adequate agitation. Always maintain agitation to avoid separation and build-up of residues.
5) Immediately after use, clean sprayer thoroughly by flushing system with water containing a detergent and rinse with clean water.
6) If a residue starts to build up in tank, drain and clean with strong detergent and ammonia solution. Then rinse thoroughly with clean water.
