Directions for use
Crops/varieties and timing
Aylora may be used on all winter and spring crops of wheat. Apply from the beginning of stem elongation (GS30) up to the end of flowering (GS69).
Aylora may be used on all winter and spring crops of barley.
Apply from the beginning of stem elongation (GS30) up to the end of heading (GS59).
Best results will be achieved from applications made as a protectant treatment or in the early stages of disease development. Apply before disease is established in the crop.
Follow up treatment with alternative fungicides may be required to provide season long control.
Up to a maximum of two treatments may be made. If following a disease risk assessment or the use of the appropriate decision support systems, a second treatment may be applied after 21 days.
Aylora is accepted by the BBPA for use on crops for malting. Crop safety Aylora is safe to recommended crops if used as directed.
 
Rate of use
Apply Aylora twice on the crop up to a maximum of 2.5 l/ha on wheat and barley. To avoid any disease resistance developing it is advisable to use Aylora® in mixture with another product of a different cross resistance group. Rates used in wheat and barley may be subject to adjustment depending on variety, tank-mix partner and disease pressure.
 
Application
Apply in 200-300 litres/ha of water using spraying equipment to give good even coverage of the crop. The higher volumes are recommended when the crop is dense. A spray pressure of 2-3 bar is recommended. Avoid spray drift onto neighbouring crops.
 
Weather
Rainfall within 2 hours of application may reduce the effectiveness of the treatment.
 
Soil
Apply under good growing conditions with adequate soil moisture. Avoid poor growing conditions, which may give less reliable results.
 
Resistance management
Use Aylora as part of an Integrated Crop Management (ICM) strategy incorporating other methods of control, including where appropriate other fungicides with a different mode of action.
 
Disease control
may be reduced if strains of pathogens less sensitive to penthiopyrad develop. When fungicides with the same mode of action are used repeatedly over several years in the same field, naturally occurring less sensitive strains may survive, propagate and become dominant in that field. A pathogen is considered resistant to a fungicide if it survives a correctly applied treatment at a recommended dose and timing, under normal weather conditions. Do not apply more than two foliar applications of SDHI containing products to any cereal crop. Users should refer to current FRAC guidelines for SDHI compounds. Disease controlled. Wheat: Septoria tritici, Leptosphaeria (syn. Septoria) nodorum, brown rust. Barley: Net blotch, Ramularia, Rhynchosporium.
 
Fungicide programmes/tank-mixes
Aylora contains an SDHI and chlorothalonil. In wheat, for the purposes of resistance management and efficacy, a tank-mix of Aylora® + triazole product has proven to provide the optimum disease control strategy. Aylora offers great flexibility in partner product choice which can be varied to suit the situation being targeted. In wheat when septoria is targeted, the partner product will typically be based on epoxiconazole or prothioconazole. In its own right Aylora® gives good control of yellow rust. When used in combination with a triazole, this is elevated to excellent yellow rust control to complement the activity on Septoria and Brown rust.
When used in barley, Aylora offers excellent control of net blotch, rhynchosporium and ramularia as well as activity on brown rust. For the purposes of resistance management and spectrum of disease control, testing has shown the addition of a partner product is beneficial. Triazole or strob partners are typical. In addition to excellent disease control, rooting improvements have been documented following applications at T1 in closely monitored experiments. This will clearly help the crop to forage for water and nutrients and is likely to be beneficial in helping the crop during short periods of drought.
 
Compatibility
Refer to Compatibility appendix.
 
Mixing
Ensure that the sprayer is clean and correctly set to give an even application at the required volume. Half-fill the spray tank with clean water and start agitation. Shake the container and add the required amount of Aylora to the sprayer using a filling device (e.g. induction bowl or closed transfer unit) or by direct addition to the sprayer tank. Wash out containers thoroughly, preferably using an integrated pressure rinsing device, or manually rinse three times. Add washings to the sprayer at the time of filling. Complete filling to the required volume and continue to agitate throughout the spraying operation. Do not leave the spray liquid in the sprayer for long periods (such as during meal breaks or overnight).
 
Spray tank clean out
Thoroughly wash out sprayer according to manufacturer’s guidelines and dispose of washings and clean containers according to DEFRA Code of Practice and local Water Authority guidelines.
