General Instructions:

MIXING

Half fill the spray tank with water and add the required amount of product with the agitator

running. Finish filling the spray tanks with water while continuing agitation. Avoid storing

spray solution in tanks overnight or over prolonged periods. Add the required amount of

surfactant to the spray solution or improving coverage and retention.

BAND SPRAYING OF COTTON

Always calibrate the spray equipment before each spraying. Check that the spray nozzles

are not worn or blocked to avoid erratic spray application. Ensure that the spray nozzles

are spaced correctly and set at a height above rows to give the desired spray band width.

e.g. for a 30cm band, mix 4.7kg product in 467L water and calibrate for a sprayed hectare

volume of 140L of solution.

Resistance Warning:

GROUP Z HERBICIDE

Huilong DSMA 500 Herbicide a member of the Organoarsenic group of herbicides with

diverse sites of action. For weed resistance management this is a Group Z Herbicide.

Some naturally occurring weed biotypes resistant to Huilong DSMA 500 Herbicide and

other organoarsenic 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 Huilong

DSMA 500 Herbicides or any other organoarsenic herbicides. Since the occurrence of

resistant weeds is difficult to detect prior to use, Huilong Agrochemicals Australia Pty Ltd

accepts no liability for any losses that may result from the failure of Huilong DSMA 500

Herbicide to control the resistant weeds.

Precautions:

Protections:

PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS

DO NOT apply under meteorological conditions or from spraying equipment which could be

expected to cause spray to drift onto nearby susceptible plants, adjacent crops, crop lands

or pastures.

PROTECTION OF LIVESTOCK

DO NOT graze treated areas or deed foliage or grass clippings to livestock or birds.

PROTECTION OF WILDLIFE, FISH, CRUSTACEA AND ENVIRONMENT

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

used containers.

Store in the closed original container in a dry, well-ventilated area, as cool as possible. DO

NOT store for prolonged periods in direct sunlight. Store in a locked room or place away

from children, animals, food, feedstuffs, seed and fertilizers.

25kg pack (paper carton with inner plastic bag): Single rinse containers before disposal.

Add rinsings to spray tank. DO NOT dispose of undiluted chemicals on-site. Break, crush,

or puncture and deliver empty packaging to an approved waste management facility. If an

approved waste management facility is not available bury the empty packaging 500 mm

below the surface in a disposal pit specifically marked and set up for this purpose clear of

waterways, desirable vegetation and tree roots in compliance with relevant Local, State or

Territory government regulations. Do not bum empty containers or product.
