4 CHEMICAL GROUP: C Herbicide - Triazine and triazinone.5 RELATED HERBICIDES:
Velpar (hexazinone) and Atrazine.
Metribuzin is in the same triazinone group.
Acetamides (Ronacil), benzothiadiazoles (Basagran), nitriles (bromoxynil), pyridazinones (Pyramin), phenyl-pyridazinones (Tough), triazines(atrazine, simazine, cyanazine, terbutryn), ureas (diuron, linuron), and uracils (Hyvar)
6 GENERAL DESCRIPTION:A translocated, leaf and root absorbed, residual herbicide for the control of annual and perennial weeds in Pine (Pinus radiata) plantations.
7 APPLICATION METHODS AND TIPS:This product may kill many trees and other desirable plants if not correctly applied.
Don't use near waterways or where water may leach herbicide to desirable species.
Best results when applied to actively growing plants and temperature is >25C. Symptoms may be slow to appear in cool weather.
Best results when applied to bare, moist soil and rain follows.
Apply from April to August in SA and WA and spring in other states when rainfall following application is expected.
Don not apply during intense rainfall periods.
On slopes greater than 20 degrees apply as a strip application.
On slopes greater than 30 degrees apply as a spot treatment.
Don't use on sandy soils that are low in organic matter or on soils that are waterlogged.
Application at least 4 weeks after transplanting is preferred.
Don't use near desirable plant or where surface water flow may carry herbicide into the rooting area of desirable plants.
Don't apply within 60 metres of dams or waterways.
9 ADJUVANTS:None recommended.
10 WATER QUALITY:Not applicable for granules.
11 COMPATIBILITY:14 HERBICIDE RESISTANCE:
Plant populations resistant to group C herbicides will probably be tolerant to Forest Mix. Repeated application may lead to the development of resistant populations of weeds.
20 MODE OF ACTION:Inhibitor of photosynthesis at photosystem II.
Uptake and translocation:Absorbed mainly by roots.
Physiological effects:Residual Life and Breakdown:
Relatively non selective.
23 PLANT SYMPTOMS:May be slow to appear in cool weather.
