3. Formulation : Wettable Powder.
4. Poison Schedule : 5
6. Product Colour : White Powder.
7. Product Flammability : Non-flammable.
8. Dangerous Goods Class :
9. Shelf Life : At least 24 months.
(When stored under ideal conditions- refer Page 4)
10. Mixtures Compatibility : 2,4-D amine (eg Amicide 500), Hoegrass (diclofop-methyl)* On Wheat NOT on peas, MCPA, Le-Mat Insecticide (omethoate), Metasystox (demeton-S-methyl) Incompatibilities are not known as only those products likely to be mixed with Tribunil are tested.
11. Registered Crop(s) : Wheat, Barley, Oats, Field Peas, Established Lucerne, Annual Pasture Legumes and Sub Clover seed crops, Demeter Fescue and Currie Cocksfoot seed crops.
12. Effect of Soil Texture on Herbicide : Little influence as it is a post-emergence spray.
13. Effect of Soil pH on Herbicide : No effect noticed.
14. Effect of Soil Organic Matter on Herbicide :
15. Mode of Action : Foliage translocated, Post-emergent.
16. Application Timing : Do NOT use on oats before 3 leaf stage.
17. Rate Variations :
18. Rates Selection : Lower rate very young deadnettle, Emex, mustard and turnip. Higher rate other very young broadleaf weeds.
19. Crop Damage (Crop Tolerance) : Oats must have 3 - 4 leaves. Legumes, Peas 2 - 3 nodes, Others 2 - 3 leaves.
20. Effect on Crop : Crop yellowing can occur when sprayed after several days of cloudy weather. No yield loss has been measured - wheat and barley tolerate Tribunil very well. Do NOT apply Tribunil to spring sown barley as it will cause unacceptable yellowing.
21a. Effect on Clover Species : Do NOT use 2,4-D Amine/Tribunil mix on undersown clovers.
21b. Effect on Medic Species : Jemalong, Paragosa, Harbinger and Borung medics may be thinned by Tribunil. In general, medics are more susceptible to damage from Tribunil than sub clover.
21c. Effect on Lucerne : Do NOT spray seedling lucerne.
22. Soil Moisture at Application :
DRY - If soil is very dry in weed root zone and weeds not actively growing, Weeds are 'hard' and not in condition for kill.
MOIST - Okay. Soil should be moist at time of treatment as methabenzthiazuron is mainly absorbed through the roots.
WATERLOGGED - Weeds not actively growing, results disappointing.
23. Frost Effects : Preceding application takes longer to work. During application weeds 'hard' takes longer to work. After application expect delayed effect.
24. Frost Free Days Required After Application :
25. Effect of Application Water Quality on Herbicide :
Saline Water - It is formulated for use in hard and soft water.
Soil Colloids - None.
26. Recommended Water Volume : 50 - 100 L/ha boom.
27. Nozzle Type : Flat fan.
28. Recommended Nozzle Pressure : 200 - 300 kPa (28.6 - 43.5 psi).
30. Recommended Wetter : Not recommended.
31. Other Additives : No.
32. Rain Fastness : 12 - 24 hours.
33. Time Interval Before Effect is Noticed : 10 - 20 days, shorter in warmer weather. Root propagated weeds survive.
34. Weed Symptoms : Symptoms exhibited by plants are typical of herbicides that are translocated through the xylem. That is, chlorosis of the leaf tips, followed by necrosis of the tips and chlorosis of the leaf. Eventually the entire leaf becomes necrotic and subsequently the entire plant is killed.
35. Effect of Herbicide/Disease Interaction on Crop : Disease renders crop less tolerant. Field peas are more susceptible to black spot.
36. Withholding Period : 14 days, 50 days for onions.
37. Plant-Back Period : Breaks down in the soil and there are no after effects on subsequent crops.
38. Spray Tank Clean-Up : Thoroughly wash with clean water.
39. Other Comments : Spray after rain.
