North: Yellow rust triggers spring spraying program

March and April have so far provided the combined total of 12mm of rainfall. Needless to say, crops are not appreciating this lack of water. It remains to be seen what the impact of this will be on yields, but the light land must be losing yield potential with every passing dry day. Yellow rust […]

Spud Special: Dry weather complicates herbicide choices

With no significant rainfall at all in April, so far, along with above average temperatures, the planting of ware crops has continued into mainly good conditions with crops emerging through the ground quickly.   Weeds are also emerging, but in dry conditions I find choosing herbicides a real challenge as the residual element relies on […]

West: Oilseed rape flowering is extremely variable

Some of my colleagues have been gently reminding me about my recent article in the 2011 Bayer Spring Crop Focus in which I stated that the 25% less rainfall we experienced in spring 2010 was “likely to be the exception rather than the norm”. But having had around 10mm here since the beginning of March, conditions […]

South: Time may not be right for new SDHI fungicides

I started my Crop Watch column last month by saying rain was desperately needed. Since then, we have had no significant rainfall and the situation is getting critical, especially on light soil types. Oilseed rape seems the worst affected on light soils and some crops are refusing to flower and are sitting at the yellow bud […]

East: Sclerotinia threat high in oilseed rape

Here in the arid east no rain is forecast for yet another week, although we can expect some lower temperatures. Personally, I have never experienced such a dry start to spring and apart from the early drilled cereals, crops are beginning to show stress symptoms. Drought conditions, coupled with the large amount of Oakley wheat, […]

East: Septoria, mildew and rusts lying in wait

A gentle soak is needed. Following an exceptionally dry period with much of eastern England receiving less than 20 per cent of the normal recorded rainfall in March, crops are showing signs of drought stress. These affects are becoming acute in some spring crops and second wheats on light or poorly structured soils. Dry conditions […]

West: Crops need rain to fulfil early promise

We have had very few wet days in the last month and we are now desperately in need of rain to wash in nitrogen and to get the spring crops going. On the other hand, it has been a wonderful time for planting spring crops. Seed-beds have been near perfect and soil temperatures have been about 4-5C above […]

South: Dry weather heightens pest activity

We had 6mm of rain at the beginning of April and that was the first for three weeks, so everything remains very dry. But surprisingly, the well established winter crops don’t appear to have suffered too much, especially those that received a reasonable early dose of nitrogen.   Earlier drilled spring crops look fine, but […]

North: Two-spray strategy for sclerotinia

Despite all crops needing a bit of moisture they are moving quickly through growth stages. Now that wind has dropped we have managed to get outstanding fertiliser and spraying jobs done ready for the next round. Winter wheat is at or around GS30 and with some approaching GS31 any main doses of nitrogen should go […]

North: Monitor oilseed rape for pollen beetles

The weather in the past four weeks has been a mixed bag. Temperatures have increased and although it has been somewhat unsettled in some localities, crop colour has improved and spring barley drilling has moved on apace. However, due to the frequent showers and the slow start to the season, cultivators are uncovering wet holes […]
