GENERAL INSTRUCTIONS

RESISTANT WEEDS WARNING

OzCrop LV MCPA/Diflufenican Selective Herbicide is a member of the phenoxy and nicotinanalide groups of herbicides and acts by inhibiting carotenoid biosynthesis and disrupting plant cell growth. For weed resistance management, LV MCPA/Diflufenican is both a Group F and a Group I herbicide. Some naturally occurring weed biotypes resistant to LV MCPA/Diflufenican and other Group F and Group I herbicides may exist through normal genetic variability in any weed population. If these herbicides are used repeatedly, resistant weeds may dominate the weed population, and they will not be controlled by LV MCPA/Diflufenican or other Group F or Group I herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, OzCrop Pty Ltd accepts no liability for any losses that may result from the failure of LV MCPA/Diflufenican to control resistant weeds.

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. Sub-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 varieties Esk and Nile (the two main varieties grown in Tasmania) to LV MCPA/Diflufenican has not been tested. Test a small area of the crop before using LV MCPA/Diflufenican over large areas. Consult your local OzCrop Pty Ltd representative for advice on specific varieties.

PASTURE

The tolerance of clover varieties to LV MCPA/Diflufenican can vary with the rate of application, soil type, crop health, stage of growth, and degree of moisture and temperature stress.

Warning: LV MCPA/Diflufenican 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, application is recommended prior to the 8th 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 LV MCPA/Diflufenican applied at 500mL/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 LV MCPA/Diflufenican on clover seed yield have been tested on the following varieties. Under normal growing conditions, they show levels of tolerance to LV MCPA/Diflufenican applied at 500 mL/ha:

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

Warning: Rose and Strawberry clover have shown increased sensitivity to LV MCPA/Diflufenican. LV MCPA/Diflufenican may affect the seed yield of subterranean variety Woogenellup. Some pasture grasses, including Phalaris and Cocksfoot, may show some initial reduction in vegetative growth after application of LV MCPA/Diflufenican. Care should be exercised if sensitive clover varieties or grasses are included in the pasture sward. Varieties not listed should be tested before using LV MCPA/Diflufenican over large areas. Consult your OzCrop Pty Ltd representative for advice on specific varieties.

SUBSEQUENT CROPS

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

MIXING

To ensure even mixing, half-fill the spray tank with clean water and add the required amount of the product. Agitate thoroughly, then add the remainder of the water. Agitate again before spraying commences. Reseal part-used product containers immediately after use. Spray mixtures containing LV MCPA/Diflufenican 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 LV MCPA/Diflufenican and some other agricultural products. To reduce the 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 if weed infestation is heavy or crop cover is dense. Complete coverage of weeds is essential.

Selective Herbicide Aircraft (NSW, Vic, SA only): Apply in a minimum of 30L water per hectare. Effective control will only be achieved where good coverage of the leaf surface is achieved.
