SPRAY DRIFT MANAGEMENT FOR GROUND APPLICATIONS
GENERAL INFORMATION:
Use good pesticide practices and apply only when the potential for drift to areas of human habitation or areas of human activity such as houses, cottages, schools and parks is minimal. Take into consideration wind speed, wind direction, temperature inversions, application equipment and sprayer settings used for applications.
For the protection of non-target habitats, over-spray or drift to any body of water or other environmentally sensitive habitats must be avoided. The interaction of many equipment and weather-related factors determines the potential for spray drift. The applicator is responsible for considering all these factors when making application decisions.

GENERAL INFORMATION
ACURON Herbicide provides selective control of annual grass and broadleaf weeds in corn. ACURON Herbicide has a high level of crop safety to allow for flexibility of application timing in corn. To ensure weed control during the critical weed free period, ACURON Herbicide may be applied preemergent and early postemergent (up to and including the 2-leaf corn stage). ACURON Herbicide will not provide control of emerged grass weeds that are past the 2 leaf stage. ACURON Herbicide contains four active ingredients and is a one-pass broad-spectrum weed control product for use in corn.
NOTE: ACURON Herbicide contains benoxacor that has been shown to enhance S-metolachlor metabolism in corn.

DIRECTIONS FOR USE
As this product is not registered for the control of pests in aquatic systems, DO NOT use to control aquatic pests.
DO NOT contaminate irrigation or drinking water supplies or aquatic habitats by cleaning of equipment or disposal of wastes.
Field sprayer application: DO NOT apply during periods of dead calm. Avoid application of this product when winds are gusty. DO NOT apply with spray droplets smaller than the American Society of Agricultural Engineers (ASAE S572.1) medium classification. Boom height must be 60 cm or less above the crop or ground.
DO NOT apply more than 4.91 L product/ha/season.
DO NOT apply any other mesotrione containing products to fields treated with ACURON Herbicide in the same year.
DO NOT apply by air.
Avoid application of this product when winds are gusty.

USE PRECAUTIONS:
ACURON Herbicide may be used pre-emergent or early post-emergent on field corn and preemergent in production seed corn and sweet corn. Not all seed corn inbreds and sweet corn varieties have been tested; the use of ACURON Herbicide must be approved by the seed company and comply with the directions given by the seed corn company.
Although ACURON Herbicide has a flexible recropping profile, certain crops may be sensitive to low concentrations in the soil. Therefore, careful consideration should be given to crop rotation plans prior to using ACURON Herbicide (refer to "RECROPPING GUIDELINES").
Dry conditions following application may reduce the preemergent activity of ACURON Herbicide. If an activating rain (>1.25 cm) is not received within 7-10 days after a preemergent application, rotary hoeing is suggested to activate the herbicide.
Do not apply to soils that contain less than 1% or more than 10% organic matter.
Temporary crop injury (bleaching) may occur under extreme weather conditions or when the crop is under stress due to inadequate or abnormally high moisture levels or extreme temperatures as well as under conditions of insect or plant disease attack, carryover of pesticide residues, use of certain soil applied systemic insecticides, improperly placed fertilizers or soil insecticides. The symptoms are most visible where excessive rates have been applied, such as sprayer overlaps. Corn quickly outgrows these effects and continues to grow normally.
Do not make a foliar postemergent application of any organophosphate or carbamate insecticide within 7 days before or 7 days after a ACURON Herbicide application or severe corn injury may occur. Syngenta Canada Inc. will not be held responsible for losses or damage resulting from such use.
Severe corn injury and crop yield loss may occur if ACURON Herbicide is applied to corn crops that are treated with Lorsban.
ACURON Herbicide may be applied prior to or following a pyrethroid-type insecticide such as FORCE Insecticide or MATADOR 120EC Insecticide.
Do not apply ACURON Herbicide through any type of irrigation system.
Syngenta will not recommend soybeans be planted the year following application of ACURON Herbicide on soils with a sand or loamy sand soil textural classification. For all other soil textural classifications, however, Syngenta will fully endorse soybeans planted the year following (11 months) application of ACURON Herbicide. Refer to “Recropping Guidelines” section for more information.

MIXING AND SPRAYING INSTRUCTIONS:
Protect sprayer operators from drift or mist. Additional information on spray drift management for GROUND APPLICATIONS is provided in the section “SPRAY DRIFT MANAGEMENT FOR GROUND APPLICATIONS”. When low volumes of spray are applied, complete coverage and thorough application are essential for most effective results. Schedule applications in accordance with local conditions. Consult your local agricultural authorities for specific use information.

APPLICATION IN LIQUID FERTILIZERS:
Nitrogen solutions (such as 28-0-0 UAN), excluding suspension and sulphur containing fertilizers, may replace water as a carrier for pre-emergence applications of ACURON Herbicide in corn. Do not use nitrogen solutions as a carrier to corn that has emerged. Always predetermine the compatibility of ACURON Herbicide tank mixes with your liquid fertilizer carrier by mixing small proportional quantities in advance. Even if ACURON Herbicide is physically compatible with a fluid fertilizer, constant agitation is necessary to maintain a uniform mixture during application.
Mixing Procedure:
1. Ensure that the sprayer is totally clean.
2. Fill the sprayer half full with water. Engage gentle agitation. All return lines to the spray tank must discharge below the liquid level.
3. Ensure that the agitation system is working properly and that it creates a rippling or rolling action on the water surface.
4. Add ACURON Herbicide slowly and agitate until completely dispersed. To ensure complete dispersion, wait 2 or 3 minutes after ACURON Herbicide has been added to the tank.
5. Fill the tank to three quarters full with water.
6. Continue agitation while completing the filling of the sprayer with water.
7. Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time. Reduce agitation once tank volume is reduced to about one third of capacity.
8. If agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying. ACURON Herbicide must be sprayed the same day as mixing. Do not allow spray solution to remain in tank overnight.
9. Do not mix, load or clean spray equipment where there is a potential to contaminate wells or aquatic systems.

RECROPPING GUIDELINES:
Certain crops have been shown to be sensitive to low residues of ACURON Herbicide in the soil. The minimum recropping interval is the time between the last application of ACURON Herbicide and the anticipated date of planting of the next crop.
To avoid injury to subsequent crops after an application at the recommended rate of ACURON Herbicide, the following recropping intervals should be observed.
CROP - MINIMAL RECROPPING INTERVAL
Field Corn, Production Seed Corn, Silage Corn and Sweet Corn - Immediately (no restriction)
Winter Wheat - 4.5 months
Spring Wheat - 10 months
Soybeans (except on sand or loamy sand soils) (1) - 11 months
All Other Crops - Bioassay (after 12 months)
(1) Syngenta will not recommend soybeans be planted the year following application of ACURON Herbicide on soils with a sand or loamy sand soil textural classification. For all other soil textural classifications, however, Syngenta will fully endorse soybeans planted the year following (11 months) application of ACURON Herbicide.
Observe the recropping guidelines of any product to be tank mixed with ACURON Herbicide. In the event of crop failure, only field corn (grain or silage), seed corn, or sweet corn can be planted as a salvage crop in the same fields in which the failed crop was treated with ACURON Herbicide. An application of ACURON Herbicide must NOT be made to the salvage crop.
Land treated with ACURON Herbicide CAN ONLY BE PLANTED TO A CROP NOT LISTED IN THE PRECEEDING TABLE if a field bioassay can be successfully performed. The bioassay must indicate normal growth with no yield reductions.
A bioassay may be conducted in any year following the year of application to assess the tolerance of the tested crop intended for planting in the year following the bioassay. Do not conduct a bioassay in the year of application. When conducting a field bioassay, it is very important to select a representative area(s) of the field previously treated with ACURON Herbicide to plant the test crop(s).
WARNING: Do not plant any crop other than corn in the same year on land treated with ACURON Herbicide as injury may occur. Crops that may be planted the following year are provided in the recropping guidelines. However, when the rotational crop is subjected to stress conditions, e.g. abnormally hot, dry weather, preceded by extended periods of dry weather the previous season, injury may occur. Do not tank mix with any other herbicide or additive unless listed on this label.
FIELD BIOASSAY
1. Representative Sample:
Ensure that soil parameters such as soil texture, depth of topsoil layer, soil pH and drainage of the test area selected are representative of the remainder of the field.
2. Sample Size:
The seeded area of each selected bioassay crop must be large enough to ensure that reliable results are obtained. The seedbed preparations and seeding of the bioassay crop(s) should be conducted the same way as when the entire field would be planted.
3. Other Residual Herbicides:
It is important that other herbicide products which are known to have residual activity were not applied to the field between the last application of ACURON Herbicide and the bioassay testing period. Avoid the use of other pesticides during the duration of the bioassay as they may damage the indicator crop(s).
4. Comparisons:
Ideally, an untreated check strip in a neighbouring field should be established and monitored for comparison since growing conditions can vary greatly from year to year and may result in erroneous results.
5. Assessment:
The site should be monitored regularly throughout the growing season. Watch for any damage to the crop such as thinning, yellowing or stunting. A yield sample should be taken and compared to an adjacent untreated field.
DO NOT ROTATE TO OTHER CROPS UNTIL THE BIOASSAY INDICATES NORMAL GROWTH WITH NO YIELD REDUCTIONS.
Failure to follow these recropping guidelines could result in injury to seeded crop(s).
