Resistance
Librax should be used in accordance with the instructions for use for the target diseases at the specific growth stages indicated.
Use Librax as part of an Integrated Crop Management (ICM) strategy incorporating other methods of control.
You must not apply more than two foliar applications of products containing complex II inhibitors to any cereal crop.
Strains of certain cereal diseases with decreased sensitivity to triazole fungicides are known to exist in the UK.
Where these occur or develop Librax may not give satisfactory control.
Librax contains metconazole, a DMI fungicide. Resistance to some DMI fungicides has been identified in Septoria leaf blotch (Mycosphaerella graminicola) which may seriously affect the performance of some products. For further advice on resistance management in DMIs contact your agronomist or specialist advisor and visit the FRAG-UK website.
 
Crops
Librax is a systemic fungicide with protectant and curative properties for use in winter wheat, spring wheat, durum wheat, winter barley, spring barley, triticale and rye.
Time of Application
Apply Librax at the start of disease attack following a disease risk assessment or the use of appropriate decision support systems. A maximum of two applications can be made up to and including flowering just complete.
Rate of Application
Apply 2 litres Librax per hectare in 100 to 300 litres of water per hectare.
Qualified recommendation Librax may be applied at 2 litres per hectare in 100 litres of water per hectare although efficacy against stem based diseases at this reduced volume has not been evaluated. Therefore application at 100 litres water per hectare is at user’s risk with regards to biological efficacy.
 
Following crops
After treating a cereal crop with Librax the following crops can be sown: barley, cabbages, carrots, clover, dwarf French beans, field beans, lettuce maize, oats, oilseed rape, onions, peas, potatoes, ryegrass, sunflowers, sugar beet and wheat. The effects of Librax on other crops has not been assessed.
 
Mixing and Spraying
Apply as a MEDIUM spray, as defined by BCPC.
Half fill the spray tank with clean water and start the agitation. SHAKE THE CONTAINER WELL before use and pour in the required amount of product. Rinse any empty containers thoroughly and add rinsings to the spray tank. Add the remainder of the water and continue agitation until spraying is completed.
When tank mixes are to be used, each product should be added separately to the spray tank, taking due note of any instructions given as to the order of mixing.
