3 ACTIVE INGREDIENTS: Prometryn 500 g/L.4 CHEMICAL GROUP: C.
Solubility - 33 mg/L in water.
It has a leaching index of 3-4. (for comparison, trifluralin is 0-1 and chlorsulfuron is 25-30).
It has a half life 50 days at 20 degrees and 50% WHC in Mohlin soil.
More prometryn is absorbed by susceptible plants in less by tolerant plants in good nutrient conditions and inactivation in tolerant plants is faster (, ) so better weed control and greatest crop safety occurs at optimum nutritional levels. In susceptible Barley and Wild Radish, prometryn concentration in plants increased with increasing levels of nutrition .
3. Formulation : Flowable liquid.
4. Poison Schedule : 5
6. Product Colour : Liquid.
7. Product Flammability : Non-flammable.
8. Dangerous Goods Class : Non dangerous good.
9. Shelf Life : In excess of 2 years.
(When stored under ideal conditions)
10. Mixtures Compatibility : If crop damage to peas is unacceptable. Do NOT mix with:- 2,4-D or MCPA
11. Registered Crop(s) : Wheat, Barley, Oats, Lucerne, Field Peas, Pastures.
12. Effect of Soil Texture on Herbicide : More readily adsorbed in soils with high clay and organic matter content.
13. Effect of Soil pH on Herbicide : None.
14. Effect of Soil Organic Matter on Herbicide : None.
15. Mode of Action : Foliar translocation, some root absorption, has considerable contact activity, therefore post-em treatments must be directed. Post-emergent.
16. Application Timing : Cereals - From 3 leaf to full tillering. Pastures - From 5 leaf stage onwards (not legume seed crops). Field Peas - More than 5 cm high. Lucerne - Established.
17. Rate Variation : 550 g to 1.1 kg/ha.
18. Rates Selection : Lower rate weeds in less than 4 true leaf stage. Higher rate weeds with 4 true leaves.
20. Effect on Crop : Possible temporary early yellowing.
21. Effect on Clover Species : Relatively safe to most common sub clover and white clover species.
22. Soil Moisture at Application :
DRY - Weed/crop stressed resulting in reduced efficacy or crop damage.
MOIST - Best results if soil moist from sowing.
WATERLOGGED - Plants stressed.
23. Frost Effects : Preceding application reduced efficacy and increased likelihood of crop damage. Up to 14 days after application may affect results.
24. Frost Free Days Required After Application : 14 days.
26. Recommended Water Volume : 50 - 110 L/ha boom.
27. Nozzle Type : Flat fan.
28. Recommended Nozzle Pressure : 200 kPa (28.6 psi).
29. Recommended Filter Size :
30. Recommended Wetter : None.
31. Other Additives : Nil.
32. Rain Fastness : Minimum 6 hours.
33. Time Interval Before Effect is Noticed : About 7 - 10 days.
35. Effect of Herbicide/Disease Interaction on Crop :
36. Withholding Period : No limitations set, but an interval of 21 days minimum should be left for weeds to be controlled before grazing/harvesting.
38. Spray Tank Clean-Up : Flush system with clean water.
39. Other Comments : Under drier conditions Gesagard 50 will not give favourable results. Will persist longer under dry or cool conditions that are not conducive to maximum chemical and biological activity. More effective on broadleaves than grasses. Weeds will emerge before dying.
