ALMOST the end of April and with 146mm (5.7in) of rain behind us, we have just managed to complete our main T1 cereal spraying.

We were lucky enough to be asked last year if we could provide a site for New Farm Crops to place a wheat trial at Grange Farm. This is one of several such trials the company has around the country to assess variety yield performance in different locations.

Along with this trial, NFC staff were kind enough to drill us about 15 varieties of wheat on an area of 0.5ha (1.2 acres), which is sufficient to be able to try four different fungicide programmes.

I do not intend to complicate things by adding other inputs, like variations in nitrogen rate or plant growth regulators, as this would only confuse the results of a small farm trial. Plots will be harvested by an NFC plot combine and taken to yield, so we should get some very interesting farm information.

The programmes I have chosen are:

1. Alto 240 (cyproconazole) at 125ml/ha with Amistar (azoxystrobin) at 600ml/ha at T1, followed by Amistar at 1000ml/ha at T2.

2. Landmark (kresoxim-methyl + epoxiconazole) at 700ml/ha at both T1 and T2.

3. Alto 240 at 215ml/ha with Bravo 500 (chlorothalonil) at 1000ml/ha at T1, followed by tebuconazole at 700ml/ha with Patrol (fenpropidin) at 250ml/ha at T2.

4. Landmark at 500ml/ha at T1 and Amistar at 500ml/ha at T2.

We will wait to see what the gods send us during May and early June before deciding on any ear wash requirements.

The winter peas continue to look tremendous, now stand a foot high and are in flower bud. It has been hard work completing the herbicide programme. As soon as they have had a few days to recover, we will begin the fungicide treatments. I intend to follow last years success of a mix of protective and systemic products, namely Bravo and Alto. &#42

Justin Blackwood hopes to glean valuable information about fungicide/ variety interactions thanks to a New Farm Crops trial on the farm.
