6 GENERAL DESCRIPTION:
Atrazine is a translocated, pre and post emergence herbicide that is mainly absorbed by the roots with some foliar absorption. It controls a wide range of weeds in tropical (C4) grass crops, triazine tolerant crops, orchards, vineyards, plantations and fallow situations.7 APPLICATION METHODS AND TIPS:
See Best Management Practices for Atrazine in Broadacre Crops.8 WEATHER:
Rainfast in 1 hour for post emergent applications. Rainfast immediately for pre emergence applications.9 ADJUVANTS:
For pre emergent applications no adjuvants are required.10 WATER QUALITY:
Hard water11 COMPATIBILITY:
Trace elements.12 EQUIPMENT:
Conventional boom sprays with flat fan nozzles applying 30 L/ha or more for pre emergence applications and 100 L/ha or more for post emergence applications are normally used. Fine nozzles are prone to blockages with many formulations.Boom sprays:
Carrier volume: 30 L/ha water or more. For post emergence applications 100 L/ha water or more is recommended if using large droplet nozzles.Aerial application:
Carrier volume: 15 L/ha water or more for pre emergence applications and 25 L/ha water or more for post emergence applications. Rainfall or irrigation after spraying is more critical for good results with aerial applications.13 SPRAYER DECONTAMINATION:
Clean Up:14 HERBICIDE RESISTANCE:
Tolerant plants are expected to occur and may dominate the weed population after repeated applications.15 REPLANTING INTERVALS:
Crop | Time |
Cereals | 6 weeks for rates up to 500 g/ha 12 weeks for rates up to 1 kg/ha 6 months for rates up to 2 kg/ha 12 months for rates up to 4 kg/ha |
Other crops | At least 6 months for crops not on the label. |
16 WITHHOLDING PERIODS:
Crop | Type | Time |
Canola (pre emergence) | Grazing | 15 weeks |
Canola (post emergence) | Grazing | 6 weeks |
All crops | Harvest | Not required when used as directed |
All other crops | Grazing | Not required when used as directed. |
17 RE-ENTRY PERIOD:
Wear protective clothing if in contact with the crop before the spray has dried.18 PROTECTIVE CLOTHING:
Overalls, boots and washable hat.19 SOIL:
Soil texture:20 MODE OF ACTION:
Inhibits photosynthesis at photosystem 2. Tolerant plants metabolise it.Uptake and translocation:
Absorbed mainly by roots with some absorption through leaves.Physiological effects:
Residual Life and Breakdown:Selectivity:
Selective or non-selective depending on timing and rate of application.21 SELECTIVITY:
Tends to provide better control of C3 grasses than broad leaved species. Species in the Fabaceae family are usually more tolerant than others species.Crop tolerance:
Some crops have been bred to be tolerant to atrazine.Varietal sensitivities:
Some varieties of Lupins and wheat are more tolerant than others.Effect on Clover Species:
Partially tolerant to low rates.Effect on Medic Species:
Partially tolerant to low rates.Effect on Lucerne:
Established Lucerne tolerates low rates.Effect on Native Plants:
Most established native plants are tolerant to low rates.22 DISEASE AND INSECT EFFECTS:
Crops with root disease or insects that attack roots are more prone to damage.23 PLANT SYMPTOMS:
Leaf yellowing and death along the edges of leaves followed by overall death. Some plants show strong veinal or inter-veinal yellowing. It usually take 1-2 weeks before effects are noticeable.SECONDARY EFFECTS:
24 TOXICITY:Details:
Poison schedule - Exempt.Symptoms
At high doses it can cause neuromuscular effects such as motor incoordination, paralysis of limbs, respiratory distress and hypothermia.Other Species -
Birds - practically non toxic.25 TOXICITY SYMPTOMS:
26 FIRST AID:27 ENVIRONMENTAL FATE:
It has a half life of 55 days at 20 degrees and 50% WHC in Mohlin soil. The half life in soil can vary considerably with Australian values ranging from 12 days to 140 days.28 REGISTERED CROPS: (Button)
29 REGISTERED WEEDS: (Button)31 PROPERTIES:
Water solubility at 25 C. - 33 ppm at pH. Moderately soluble, slightly hydrophilic.Usage
2100 tons of active ingredient was sold in Australia in 1998.33 REFERENCES:
