Restrictions
Talius should not be applied to any crop suffering from stress as a result of drought, waterlogging, low temperatures, nutrient or lime deficiency or other factors reducing crop growth. Avoid application in either frosty or hot, sunny weather conditions. Up to 2 treatments may be applied per crop, however the second application must be tank-mixed with an alternate mode of action mildewicide. There is a possibility that some crops, particularly oilseed rape and other brassicas, may suffer adverse effects from Talius, care should therefore be taken to avoid drift onto non-target crops.

Following crops
There are no restrictions on crops that may be grown following harvest of a cereal crop treated with Talius.

General information
Talius is a unique fungicide for the control of powdery mildew in cereals. It is extremely active with a new mode of action, which inhibits spore germination and the formation of mildew appressoria, in addition to inducing the cereal plants’ natural host resistance mechanisms. Talius offers locally-systemic, translaminar activity providing a more uniform barrier against infection. Its vapour activity also shields both treated and untreated foliage from re-infection. Talius gives 4 to 6 weeks protection from a single spray depending on dose rate - typically 2 weeks longer than competitor mildewicides. Talius has controlled all strains of mildew against which it has been tested. These have included strains known to be resistant to other chemical groups. Talius also boosts control of other cereal diseases provided by tank-mix partners. Increases in disease control have been noted for Septoria, eyespot, Rhynchosporium, net blotch and rusts.

Crops/varieties and timing
Talius can be used on all varieties of wheat, barley, oats, rye and triticale. Talius can be applied at any time before full flowering (GS 65) on wheat or before beginning of heading (GS 49) on barley, oats, rye and triticale. Up to a maximum of 2 treatments may be made. Being protectant in nature, an application of Talius® should be made when mildew levels are not already compromising crop health. Where disease levels are high, Talius should be applied with a curative partner e.g. a morpholine. If a second treatment is required, typically 4 - 6 weeks after the first application, it must be tank-mixed with an alternate mode of action mildewicide (see Compatibility). Talius is accepted by the BBPA for use on crops for malting.

Crop safety
Talius is safe to recommended crops if used as directed. Care should be taken not to overlap spray swaths.

Rate of use
0.25 litres per hectare. Lower rates may be recommended in appropriate tank-mixes.

Application
Apply in 150 - 400 litres of water per hectare as a medium quality spray (as defined by BCPC). A spray pressure of 2 - 3 Bar is recommended. Do not use increased concentrations beyond the maximum given above.

Limit to number of applications
2 per crop.

Weather
Avoid application in either frosty or hot, sunny weather conditions.

Resistance management
Powdery mildew has a history of wide spread resistance to chemicals and failure to follow resistance management action may result in reduced levels of control. Development of resistance can be avoided or delayed by alternating or mixing products having an alternate mode of action (see Timing). Use Talius as part of an Integrated Crop Management Strategy (ICM) incorporating other methods of control, including where appropriate other fungicides with a different mode of action. Although proquinazid has been shown to control mildew strains resistant to quinoline, for resistance avoidance purposes proquinazid should be regarded as a quinoline type fungicide. 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.

Disease controlled
Talius controls Powdery mildew in cereals. Being protectant in nature, applications of Talius should be made when mildew levels are not already compromising crop health. If mildew levels are compromising crop health, Talius should be tank-mixed with a curative, alternate mode of action mildewicide e.g. morpholine. When a second spray is used consecutively, Talius should be tank-mixed with an alternative mode of action fungicide with activity against powdery mildew.

Compatibility
Talius has been widely tested in both physical and biological compatibility tests and has caused no problems in tank-mixes. Where a mildewicide is known to be compatible in a tank-mix, DuPont will endorse its replacement with Talius(see Compatibility appendix).

Mixing
Half-fill the tank with clean water, add the required amount of Talius and continue agitation while topping up the tank and while spraying. Wash out container and add washings to the spray tank.
