Agro-Essence 2,4-D 300 Herbicide is a water-soluble liquid product with non-selective herbicidal activity against broadleaf weeds. Agro-Essence 2,4-D 300 Herbicide will control emerged weeds only and provides no residual control although certain plant back periods should be observed. Agro-Essence 2,4-D 300 Herbicide is absorbed by plant foliage and accumulates to toxic levels in the regions of growth and reproduction, upsetting the ability of plants to balance the synthesis and use of nutrients. Visible effects are a gradual yellowing and wilting of the plants which advances to complete browning of above ground growth and deterioration of root systems. Effects may not be apparent for 7-10 days or even up to 21 days under cold or cloudy conditions.
DO NOT treat weeds under poor growing or dormant conditions such as occur in drought, water-logging, disease, insect damage, following frost, weeds heavily covered with dust or silt. Reduced results may also occur if weeds are under stress from previous herbicide application.
Rainfall occurring up to 6 hours after application may reduce effectiveness.
DO NOT spray if strong winds prevail.

Crop Establishment
Agro-Essence 2,4-D 300 Herbicide is recommended as a herbicide additive to Glyphosate (450 g/L) for control of emerged weeds prior to crop establishment. When Agro-Essence 2,4-D 300 Herbicide is applied prior to crop establishment, certain Plant Back Periods should be observed to ensure that the herbicide has degraded sufficiently to allow safe sowing of the intended crop. This process is largely-influenced by moisture, temperature and certain soil characteristics and may be delayed particularly when conditions are cold and dry. Refer to the Plant Back Period table for specific information. In seasons of heavy weed growth, or where the following conditions apply, it may be necessary to further delay sowing until a suitable seedbed can be formed. Conditions which can delay crop germination and seedling development include:
• Heavy green or decaying weed growth incorporated into the soil,
• Soil compaction or crusting,
• Cold and wet soils,
• Deep seeding;
• Prior use of residual or pre-emergent herbicides.
To minimise these affects it is suggested that:
• Weed bulk be reduced by grazing and cultivation to leave trash on the surface to dry out,
• A friable seedbed should be produced by cultivation, where necessary,
• The use of pre-emergent herbicides to be avoided if they might contribute to reduced germination,
• A correct seedling depth to be used.
The preferred alternative is to spray early to control any weeds in their less advanced stages and ensure the seedbed is in a suitable condition for early sowing when soil temperatures are not excessively cold.

Application
Boom Equipment
Tank mixtures of Agro-Essence 2,4-D 300 Herbicide and Glyphosate should be applied in spray volumes of between 25-100 L/ha is recommended. When 750g/kg chlorsulfuron or 600g/kg Metsulfuron-methyl is included in the mixture a minimum spray volume of 30 L/ ha is recommended. When Simazine is included in the mixture a minimum spray volume of 100 L/ha is recommended. Flat fan nozzle equipment is recommended using pressures in the range of 240-280kPa. Boom height must be set to ensure double overlap of nozzle patterns at the top of the weed canopy.

Aerial Equipment
Tank mixtures of Agro-Essence 2,4-D 300 Herbicide and glyphosate should be applied using either Micronair or boom equipment should in a minimum spray volume of 15 L/ha.
Droplets with an average size of 250-350 micron diameter are recommended. Swath width should be 15-17 metres.

Application Under Hot Conditions
High temperatures and/or low relative humidity cause excessive evaporation of spray droplets which may reduce results. When temperatures reach 25 ºC increase water volume to 30 L/ha and increase droplet size to at least 300 micron diameter.
DO NOT apply by aircraft when temperature is above 35 ºC.
DO NOT use in intensive horticultural cropping areas.
Thoroughly wash aircraft, especially landing gear after each day of spraying to remove herbicide residues
