General Instructions

 

Crop Tolerance

Some pre-emergence herbicides, such as atrazine, can cause stress to certain crops resulting in an increase in crop damage when using this product. Subterranean clover is particularly sensitive.

 

Cereals

After application some transient crop yellowing may occur. This usually appears as yellow or white banding on leaves. Provided the crop is not under stress from pre-emergent herbicide, root disease, insect damage, frost, dry or excessively moist conditions, the development of the crop and subsequent growth will be unaffected.

 

Warning (Oats)

The tolerance of oat varieties Esk and Nile (the two main varieties grown in Tasmania) to Jester Herbicide has not been tested. Test a small area of crop before using Jester Herbicide over large areas. Consult your local Cheminova representative for advice on specific varieties.

 

Pasture

The tolerance of clover varieties to Jester Herbicide can vary with rate of application, soil type, crop health, stage of growth and degree of moisture and temperature stress.

 

Warning

Jester Herbicide may result in transient crop yellowing and suppression of growth with a resultant initial reduction in dry matter, particularly at rates in excess of 500 mL/ha and in areas of double spray. For this reason we recommend application prior to the 8 trifoliate leaf stage. However, at the lower rates (500 mL/ha and less) and under normal growing conditions, subsequent growth and seed yield should not be affected.

 

Under normal growing conditions, the following varieties have shown acceptable levels of foliage tolerance to Jester Herbicide applied at 500 mL/ha:

ArrowLeaf: Zulu

Balansa: Paradana

Berseem: Sacromonte

Persian: Kyambro, Lupers, Maral

White: Haifa

Subterranean clover: Daliak, Dalkeith, Denmark, Esperance, Geraldton, Goulburn, Karridale, Larissa, Leura, Mt. Barker, Nungarin, Rosedale, Seaton Park, Trikkala and Woogenellup.

 

The effects of Jester Herbicide on clover seed yield have been tested on the following varieties. Under normal growing conditions they show acceptable levels of tolerance to Jester Herbicide applied at 500 mL/ha:

Subterranean clover: Esperance, Goulburn, Larissa, Seaton Park and Trikkala.

 

Warning

Rose and Strawberry clover have shown increased sensitivity to Jester Herbicide. Jester Herbicide may affect the seed yield of subterranean clover variety Woogenellup.

 

Some pasture grasses, including Phalaris and Cocksfoot, may show some initial reduction in vegetative growth after application of Jester Herbicide.

 

Care should be exercised if sensitive clover varieties or grasses are included in the pasture sward.

 

Varieties not listed should be tested before using Jester Herbicide over large areas. Consult your local Cheminova representative for advice on specific varieties.

 

Subsequent Crops

To reduce effect on subsequent susceptible crops (e.g. canola), ensure thorough cultivation of soil prior to the sowing of these crops.

 

Mixing

 

To ensure even mixing, half fill the spray tank with clean water and add the required amount of product. Agitate thoroughly then add the remainder of the water. Agitate again before spraying commences. Reseal part-used product container immediately after use. Spray mixtures containing Jester Herbicide should not be left to stand overnight. Prolonged periods of exposure to cold temperatures could result in settling out of the product in the mixture.

 

Warning

The rubber components present in some spraying units may be affected by exposure to the solvents in Jester Herbicide and some other agricultural products. To reduce this risk it is recommended that the spray unit be thoroughly washed with a boom cleaner and fresh water after use. Contact the spray unit manufacturer to determine the suitability of the rubber components for use with agricultural products.

 

Application

 

Boom Sprayer

A minimum of 50 L of water per hectare should be used, however, for optimum results water rates of 70-100 L/ha are recommended. Increase the water volume of weed infestation is heavy or crop cover is dense. Complete coverage of weeds is essential.

Aircraft (NSW, Vic, SA only)

Apply in a minimum of 30 L water per hectare. Effective weed control will only be achieved where good coverage of leaf surface is achieved.

 

Compatibility

The following products are physically compatible with Jester Herbicide as a twoway mixture in the spray tank but should only be used for the crops specificed See label). When mixing with other herbicides, crop yellowing may be enhanced. When mixing with Cheminova Diclofop methyl, Wildcat, Puma Progress or Tristar Advance some reduction in the efficacy and speed of action of these products may occur. If the crop is stressed, the application of the herbicide tank-mixtures may cause yield reduction. When mixing with Cheminova Dicamba a temporary wilting may be evident in some crops after application. Growers should seek advice before spraying recently released cereal varieties.

 

Use the recommended rates for both herbicides in the tank-mixture as well as the surfactant recommendation of the grass herbicide. If another herbicide is applied as a tank mix, observe the plantback restrictions on that label. DO NOT add surfactant when mixing Jester Herbicide and Cheminova Metsulfuron 600. Simazine: Refer to the simazine label for correct application rates, especially with regard to soil types.

 

This product may be mixed in the spray tank with one of the following insecticides according to the directions for use on this product: Hallmark 50EC, Cheminova Alphacypermethrin 100, Karate, Decis options, and Cheminova Bifenthrin 100.

 

Warning

DO NOT use crop oils with Jester Herbicide or Jester Herbicide tank mixtures with other products in cereals.

 

As formulations of other manufacturer's products are beyond the control of Cheminova, all mixtures should be tested prior to mixing commercial quantities.

 

Restraints

 

DO NOT apply if crop or weeds are stressed due to dry or excessively moist conditions.

 

DO NOT apply to crops under stress due to disease or insect damage.

 

DO NOT apply to frost-affected crops or if frosts are imminent.

 

DO NOT apply when heavy rain is expected within 4 hours.

 

Resistance Warning

 

Jester Herbicide is a member of the phenoxy and nicotinanilide groups of herbicides and acts by inhibiting carotenoid biosynthesis and disrupting plant cell growth. For weed resistance management Jester Herbicide is both a Group F and a Group I herbicide. Some naturally occurring weed biotypes resistant to Jester Herbicide and other Group F and Group I herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by Jester Herbicide or other Group F or Group I herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Cheminova accepts no liability for any losses that may result from the failure of Jester Herbicide to control resistant weeds.

 

Protection of wildlife, fish, crustaceans and environment

Dangerous to fish. DO NOT contaminate streams, rivers or waterways with the chemical or used containers.

 

Protection of crop, native and other non-target plants

DO NOT apply under weather conditions or from spraying equipment, that may cause drift onto nearby susceptible plants/crops, cropping lands or pastures. Avoid spray drift and vapour movement onto susceptible crops such as cotton, tobacco, tomatoes, vines, lupins, fruit trees and ornamentals.

 

Safety Directions

 

Harmful if swallowed. Will damage the eyes. Will irritate the skin. Avoid contact with eyes and skin. When opening the container and preparing the spray, wear cotton overalls buttoned to the neck and wrist, washable hat, elbow length PVC gloves and face shield or goggles.
