April 2016 general field recommendations

With Easter out of the way we are into April and the meat of the growing season, with the opportunity to ensure we support each crop’s individual needs. After a number of dry weeks, which have allowed flood waters to recede, storm Katie provided another dose of heavy rain in many places. The outlook for the rest of the month doesn’t indicate that our weather should be anything other than typical April showers with a normal range of temperatures.

Most of you will be getting your T1 sprays on the cereals and it is important to remember that this spray needs to be a robust fungicide on the barley. There is a need to add some manganese with the T1; barley will go through growth fits and starts in April and those fits and starts are evened out by the application of a quality manganese product like Amix manganese or BroadAcre manganese with that T1 spray. Additional magnesium maybe required, so keep a look out for that crinkling at the edge of the leaf which can be mistaken for Rhynchosporium; if you see that you definitely need some magnesium.

In the wheat, septoria and rusts are still the main diseases we are fighting and it’s important that we remember that the Amix formulation will help your T1 fungicide. Personally I would always advise some chlorothalonil whenever you go through with the sprayer as it helps defeat resistance and maintain a constant attack on the development of septoria throughout the crop. Wheat is also going to benefit, particularly on the higher organic soils, from a T1 manganese. Zinc is starting to become an element that is contributing more and more to growth and development, as the zinc that is available within the root zone is utilised by each year’s crop and due to minimal tillage it is not replaced from the lower levels of the soil structure. So think about replacing a little bit of zinc with your manganese especially if you have been using minimal tillage for a number of years. Magnesium is unlikely to be an issue unless you are on calcareous soils but look out for those older leaf symptoms.

Potato planting is well underway and Pro bio TP offers both a source of manganese and zinc along with phosphite solublising bacteria to the potato grower. When applied as a seed treatment, it is capable of providing some very economic benefits to the potato grower.

All of the broad leaf crops, peas and beans, would benefit from an early phosphite to keep downy mildew at bay and to help promote development. As with all legumes we have Amix Legumol which is a combination of cobalt and molybdenum. Just a quarter of a litre per hectare at the early vegetative stage will promote additional nitrogen fixing root nodules to establish those crops quickly and with the maximum available nitrogen to get the maximum leaf area during the important early stages of growth.
