The graminicide Centurion MAX was launched last autumn and the vast majority of users have been thrilled with the excellent level of black-grass control achieved in winter oilseed rape. With one autumn, and a difficult one at that, under its belt, Interfarm is taking the opportunity to assess the pros and cons and are consequently issuing new guidelines so that grower can get the very best from this exceptional chemical.

A prolonged and warm winter has allowed both mites and insect pest infestations to escalate in grain stores and without an effective broad-spectrum treatment these infestations could attack grain as it is placed into the store following harvest and so reduce its value and even lead to rejection. Growers need to plan how they will tackle this potential problem which could reduce grain quality and price.

Apple growers are looking for ways of reducing or eliminating expensive hand thinning so that they can produce the right balance of crop load and fruit size more cost-effectively. There are suitable products such as 6-benzyladenine that will increase the number of single fruits and so thin apples chemically, but they need to be applied precisely within the correct conditions of application.
With reports of spring-germinating wild-oats showing up in wheat, growers are being advised to plan which fields would need an herbicide application later on this spring, according to Stewart Woodhead, Technical Manager, Interfarm UK Ltd.
“With the economic threshold being just 1 plant every 2 square metres, growers should be prepared to apply a post-emergence herbicide when weed emergence is complete. Spring germination of wild-oats started this spring around the end of March. So there is time for the rest to emerge before applying a contact herbicide, but this year crops are more advanced than normal, with one third of the area at stem extension at the end of March.
It will be a busy season ahead for growth regulation as there are many forward cereal crops with high plant counts. Winter crops were drilled in good conditions, established well in the autumn and they have moved through the growth stages rapidly, to reach the spring well ahead of normal.

With temperatures rising and day lengths extending, two-spotted spider mites (Panonchyus ulmi) in ornamental nurseries are reported to be coming out of diapause early and will need knocking back with an appropriate chemical before introducing Phytoseiulus as part of an Integrated Pest Management approach. The contact-acting acaricide Borneo has an Extension of Authorisation for Minor Uses (EAMU) for use in protected ornamental plant production to add to its label recommendations in protected tomatoes and aubergines and its EAMU in protected strawberries.

Docks have continued growing throughout the winter and are now ready to grow rapidly as soon as the weather warms up. They could start growing earlier than usual, but nevertheless need to be controlled in order to maintain silage quality, grassland yield and palatability. Docks are generally unpalatable to animals so the more docks you have, the less palatable your stock will find your pasture.
