Apply as a MEDIUM spray, as defined by BCPC.
Terpal is recommended for use as a component of an intensive growing system where provision of optimum basic and nitrogen fertilisation has been made together with appropriate disease control measures.
The nitrogen fertiliser rates should not, however, be increased without careful consideration of all the factors affecting the condition and the growth of the crop.
The optimum effect of Terpal may be expected in a vigorous, actively growing crop, having a good plant population with an adequate nutrient and moisture supply. The greatest response will be seen in crops sprayed at the correct timing and when good growing conditions prevail at and after application.
Terpal has been safely applied and has given benefits on all winter and spring barley and winter wheat and triticale varieties with or without previous CeCeCe 750 growth regulator application.
When using Terpal an authorised non-ionic wetter must be added to the spray tank at the rate of 40 ml per 100 litres spray solution.
APPLICATION
Time of Application
Timing of application is particularly critical. Terpal may be applied from when the second node becomes detectable on the majority of tillers (GS Zadoks 32) up to and including when the ligule of the last leaf is just visible on the majority of tillers (GS Zadoks 39).
Optimum time
For the best results Terpal should be applied when the flag leaf is just visible but still rolled up (GS Zadoks 37). Early applications (at GS Zadoks 32) are only recommended to dense and vigorously growing crops which are prone to early lodging.
MIXING
Half fill the spray tank with clean water and start the agitation. Pour in the required amount of Terpal and, separately, the correct amount of authorised non-ionic wetter. 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.
