Balance - Summary Active ingredient: 750 g/kg Isoxaflutole (IFT) - PowerPoint PPT Presentation

Balance - Summary • Active ingredient: 750 g/kg Isoxaflutole (IFT) • WDG (1.5kg pack) • NEW chemistry: Isoxazole (Group F) • Low solubility • Low toxicity • Low environmental loading • Activated by moisture (“Recharge activity” in dry soils)

Balance - Activity • Uptake: Primarily by root and shoot absorption • Site of Action: Meristematic and developing shoot tissues. • Mode of Action: Inhibits key enzyme for carotenoid biosynthesis/chlorophyll protection • Symptoms: Affected seedlings fail to emerge or emerge, turn white and die. • Light has no impact on stability

Balance - Directions for use

Balance - Application • Chickpeas PSPE only (bare soil after planting) • 100 g/ha alone or tankmixed with simazine • Key weed registrations on Indian hedge mustard, Capeweed, Prickly lettuce, Turnip weed, Sowthistle and Wild radish. • Apply by ground spray rig • DO NOT incorporate • Stubble cover has virtually no effect • No rainfast period, can apply while raining • Addition of knockdown herbicide will control weeds already present

Crop Safety on Chickpeas

Balance Crop Safety

Balance - Variety Tolerance

Balance PSPE - Safety to Chickpeas • Establishment counts show no effect from Balance. • Slight chlorosis and biomass reductions sometimes observed, but not to a concerning level. Can be greater in dry seasons. • Chickpeas grown on very light soils (<10% clay) have shown greater effects from Balance. These soil types are not recommended.

Re-cropping - Status • Current: – Apply Balance 750 WG only to cropping areas which are to be left to fallow, – Or where the following crop will be either chickpeas, cereals or maize. – Suggested or indicative plantbacks are: • Canola > 10 months (could be 18 months) • Field pea 10 months • Faba bean, 10 months • Sub clover 10 months • Vetch 9 months • Maize 4 months – Plantback for lablab, mungbean, soybean, sorghum, sunflower, cotton are greater than 4 months with further results required. – Minimum rainfall for each crop plantback situation yet to be described.

Other Considerations • Compatibility: – Balance may be tank-mixed with simazine formulations at the appropriate label rates for each product. Balance should not be tank-mixed with trifluralin. – No additional mix partners are planned. • Stubble Effects: – Weed control appears marginally lower for weed control (<5%), however commercial results have shown good control under a range of stubble covers – suggesting rainfall after application is more important than level of stubble. • Rainfall: – Main weed control concern with lack of rainfall is possible loss of activity for wild radish control - this is being investigated.

Balance - Summary • An unrivaled herbicide for broad-spectrum weed control in chickpeas. • High loading WDG (750 g/Kg) • Group F • PSPE • Easy rate alone - 100 g/ha • Easy tank mix option with simazine to broaden spectrum (grasses etc.) - 100g/ha + 1 - 1.5L/ha
