(When stored under ideal conditions- refer Page 4)

10.	Mixtures Compatibility : Atragranz/Atradex 900 WDG (atrazine)

Roundup (glyphosate) Flowable atrazine

Shirquat W (paraquat + wetter) Avadex BW (tri-allate)

Spray.Seed (paraquat + diquat) diuron/Diurex 900 WG

Stomp 330E (pendimethalin) Gramoxone (paraquat)

Do NOT mix with :- Supracide 400 (methidathion)

11.	Registered Crop(s) : Lupins, Faba Beans, Apples, Pears, Vines, Roses, Citrus, Strawberries and Asparagus.
12.	Effect of Soil Texture on Herbicide : Heavier soil types require higher rates.
13.	Effect of Soil pH on Herbicide : Increasing soil pH decreases the rate of breakdown.
14.	Effect of Soil Organic Matter on Herbicide : Increasing levels of organic matter requires higher rates.
15.	Mode of Action : Root absorption, Pre-emergent.
16.	Application Timing : Apply to bare, moist soil at or within 2 days of sowing/before weed seeds germinate.
17.	Rate Variations : 900 g - 2.5 kg/ha.
18.	Rates Selection : Lower rate light soils, low in organic matter. Higher rate heavier soils and/or high free organic matter or crop residues are present.
19.	Crop Damage (Crop Tolerance) : Growth stages definition - applied to established perennial crops as indicated by age after planting.

Crop Growth Stage

Vineyards + 12 months (after planting) 3 yrs or older

Berry Fruit + 12 months (after planting)

Roses + 12 months (after planting)

Citrus + 12 months (after planting)

20.	Effect on Crop : No problems at label rates on registered crops.
21.	Effect on Clover Species : Not normally a problem.
22.	Soil Moisture at Application :

DRY - Weed control may be reduced if irrigation or rain is not received within 7 - 10 days of application.

MOIST - Herbicide is bonded to soil particles and good weed control should ensue.

WATERLOGGED - Simazine may be hydrolysed under these conditions resulting in loss of active constituent and poor weed control.

23.	Frost Effects : Stress resulting in reduction in root activity of weeds will result in poor uptake of active constituent and hence poor weed control.
24.	Frost Free Days Required After Application : Not applicable.
25.	Effect of Application Water Quality on Herbicide :

Saline Water - Not known, not normally a problem.

Soil Colloids - Not normally a problem.

26.	Recommended Water Volume : Minimum 100 L/ha boom.
27.	Nozzle Type : Flat fan ensuring even coverage.
28.	Recommended Nozzle Pressure : No particular requirement.
29.	Recommended Filter Sizes : 50, 80 or 100 mesh are acceptable 120 mesh NOT acceptable. Incitec recommends that 50 - 80 mesh only in the in-line and nozzle filters.
30.	Recommended Wetter : Not applicable.
31.	Other Additives : Not applicable.
32.	Rain Fastness : Requires rain for incorporation.
33.	Time Interval Before Effect is Noticed : 7 - 10 days.
34.	Weed Symptoms : Chlorosis.
35.	Effect of Herbicide/Disease Interaction on Crop :
36.	Withholding Period : Not applicable.
37.	Plant-Back Period :

Sensitive crops + 9 months at rates up to 2.5 kg/ha

Sensitive crops Very long period at rates over 2.5 kg/ha.

38.	Spray Tank Clean-Up : Thoroughly flush out tank and equipment with clean water.
39.	Other Comments : Is registered for weed control near trees and shrubs at 4 kg/ha, therefore spray tank flushing will not normally be a problem.

Breakdown equation R=1.021*10^0.015 in WA.

Where there is compete cover of stubble on the ground, 30-40% of the applied simazine may be lost (absorbed) .

Application of simazine after seeding in reduced tillage systems may damage the crop (especially cereals and canola).
