For the pre-emergence control or suppression of certain annual grass and broadleaf weeds in imidazolinone herbicide tolerant barley, wheat (single gene) and canola; and for the early post-emergence control or suppression of certain annual grass and broadleaf weeds in imidazolinone herbicide tolerant canola and wheat (single gene).

GENERAL INSTRUCTIONS
Crop Care Sentry™ Herbicide is for use pre-emergence in imidazolinone herbicide tolerant barley, wheat (single gene) and canola varieties only and for use post emergence in imidazolinone herbicide tolerant canola and wheat (single gene) varieties. Varieties with imidazolinone herbicide tolerance are those which have been bred specifically to tolerate imidazolinone herbicides. Sentry is an imidazolinone herbicide combination that provides both soil and foliar activity. Soil activity can be variable when dry soil conditions prevail following application because the product is not freely available to weeds. Best pre-emergence weed control will be achieved when soil moisture at or soon after application is good allowing the roots of germinating weed seedlings to take up the herbicide. Best post-emergence weed control will be achieved when application is made to young actively growing weeds. The pre-emergence use of Sentry will assist crop establishment and protect yield potential but may not preclude follow-up post-emergence weed control. When applied post-emergence Sentry must be mixed with Supercharge Elite as per the Directions for Use. Weeds treated post-emergence will either die or will remain stunted and will not compete with the crop. Vigorous crop growth will assist in suppressing weeds not completely killed or germinating later.

MIXING
Sentry is a water dispersible granule formulation. Part-fill the spray tank with water, then with agitator running, add the required amount of product. Once completely dissolved add the required quantities of recommended products, in the correct mixing order, whilst filling the remainder of the tank. For large tank loads requiring large amounts of Sentry, or in situations where agitation is insufficient, consider premixing Sentry and then adding the pre-mix to the spray tank.

APPLICATION
Generally, apply in a minimum 70L water per hectare. For post-emergence situations where grass weed populations exceed 200 plants per m2 , apply in a minimum of 100L water per hectare. When used alone post-emergence, Sentry Herbicide should be applied a minimum of two hours before rainfall or overhead irrigation. In mixtures with Transit or Havoc, application should be made a minimum of three or six hours (as per advice for these products) before rainfall or overhead irrigation.

COMPATIBILITY
Sentry is compatible with the following insecticides: Mascot Duo, Saboteur, dimethoate and omethoate. Sentry is compatible with the following herbicides: Transit Herbicide, Havoc Herbicide, Trifluralin 480, Triflur X, Approve, Avadex Xtra, Avadex Xtend, Rifle 440 Herbicide, Sakura* 850WG Herbicide, Gladiator OptiMAX, WeedMaster DST, Alliance, Revolver, Shirquat 250, Romper 440EC and Factor Herbicide.
Sentry is compatible with the following oils: Supercharge Elite, Banjo, Hasten* or Kwickin*.
When applying Sentry pre-emergence tank mixed with grass herbicides, use either Triflur X at up to 3 L/ha, Avadex Xtend at 1.3L/ha for wild oats control or Triflur X at up to 2L/ha plus Avadex Xtend at up to 1.7L/ha based on weed profile and conditions. Tank mixes with grass herbicides are recommended as a sound herbicide resistance management strategy but are encouraged when a high grass weed burden is expected or when Group B resistance is suspected. These mixes can also assist broadleaf weed control. Tank mixtures of Sentry and these various grass herbicides can be applied with the knockdown herbicides and insecticides indicated but more complex mixes have not been tested.
When applying Sentry post-emergence tank mixed with Transit or Havoc use 150 – 200mL/ha Transit (depending on legume and composite weed burden) and 175 – 500mL/ha Havoc (depending on grass burden and Group A resistance status). When applying Sentry with a mix of Transit and Havoc note that Transit can impact on grass control and should not be used at 200mL/ha with low rates of Havoc.
DO NOT tank mix with foliar fertilizers.
