To get the best from Escolta, apply a T1 spray as disease enters the crop before it has become established. Apply your T2 spray three to four weeks afterwards and by mid-September, at the latest, to give full protection to crops lifted from the latter half of October onwards, and to maximise leaf-greening.
Important things to remember
- Escolta will give a physiological boost to yield, even in situations where disease pressure is very low.
- For best results apply Escolta prior to the onset of disease
Escolta as part of a two-spray programme
T1 sprays are typically applied in late July or early August. Escolta persists for three to four weeks, so a well-timed T1 spray will keep the crop protected right through the cereal harvest and into September.
Assess the need for a T2 spray in late August or early September depending on disease pressure and planned lifting. Escolta’s short harvest interval of 21 days provides the flexibility to take advantage of a T2 spray and lift early. In a year where there is significant disease pressure, a T2 spray gives an economic response where October lifting is planning. A healthy crop can continue to gain 3t/ha per week during October.
Where you are lifting beyond October, a T2 spray gives full protection into the winter. In addition to building yield it helps to maintain a healthy canopy and protect roots and crowns from frost damage.
