Spraying and applying the last of the nitrogen to later-sown spring crops took priority over the past number of weeks.

Around 56mm of rain has fallen on Ronan’s farm since talking to him last, which has been more than enough to keep crops ticking over. The rain, combined with warmer nights over the past week, has been perfect for crop growth.

Last week, he had to apply a follow-up herbicide on some of his potato crops to tidy up wild oats. The tubers in his earlier-sown potato crops are around 10mm in diameter and he expects to be digging these in six to seven weeks.

He also applied the crop’s first blight spray last week of Shirlan (100ml/ha), Moximate (2kg/ha) as well as Spavario (50ml/ha). There were some cases of sclerotinia in the area but blight pressure remains very low.

At 60cm in height, his early sown spring beans are looking well and are beginning to flower. The crop is due to receive Signum (0.75kg/ha), Rover (1l/ha) and Superphite pro (1.5l/ha). It also needed another application of Basagran (0.8l/ha) in order to knock out fumitory and thistles.

He expects the awns to emerge on his malting spring barley in a couple of weeks. The crop received its T1 last week of Opus Team (0.8l/ha), Comet (0.4l/ha) as well as Axial Pro (0.5l/ha).There’s a small amount of rhynchosporium in the crop. As the crop received all of its nitrogen at an early stage, it is progressing through its growth stages at a fast pace.

His spring wheat received an application of CCC (1l/ha), Moddus (0.1l/ha), Opus Team (0.8l/ha), Avoca (1l/ha) and Talius (0.12l/ha) last week. The crop was also topped up to 165kg N/ha last week using UAN liquid nitrogen. The spray was applied in dull conditions but the crop appears to have been scorched by the nitrogen. Ronan wonders if his new nozzles may have had an effect on this.

His winter crops are standing well. He applied a T2 of Osiris P (1.25l/ha) on his winter wheat but increased this to 1.4l/ha on his Bennington crops which had high levels of yellow rust infection. His crops also received Imtrex (1.25l/ha) and Avoca (1l/ha) in that mix. Some of his crops are now heading out.

The past month has been a showery one on David’s farms, with over 64mm having fallen since speaking to him last. Despite the rain, ground is holding up well and there have been reasonable windows for spraying.

His winter wheat crops have been slow to develop and as a result of a long interval between T1 and T2 timings and increased disease pressure, he applied a holding spray on the crop. He applied Bravo (1l/ha) and prothioconazole (0.4l/ha) on to the crop a number of weeks ago.

“Septoria was beginning to show and I would have been concerned if it was left any longer,” David explains.

The flag leaf is now fully emerged and last Tuesday he applied a T2 consisting of Elatus Era (0.8l/ha), Bravo (1l/ha), Opus Team (0.8l/ha) as well as Cerone (0.25l/ha).

His winter barley crop appears to have “reasonable potential” this year and is standing well for now, he remarks. There are spots of ramularia and rhynchosporium appearing in places in the lower canopy, however.

His winter oats are close to heading out but disease levels remain low. The crop will receive a T2 of Jenton (0.8l/ha), Talius (0.15l/ha) as well as Combitop (5kg/ha).

His spring barley crops have tillered well and look lush and green. Malting and feed crops have received a T1 of Siltra (0.45l/ha) and as well as Moddus (0.15l/ha) and CCC (1l/ha). Crops are approaching GS31 and there is some rhynchosporium visible. His feed barley was topped up with nitrogen (25 kg N/ha) two weeks ago and some of his crops received a second manganese trace element spray. The crop has received no aphicide.

His spring wheat was brought up to 137kg N/ha two weeks ago and is progressing well. The crop will be due a T1 fungicide within the next week or two.

David had to re-sow a patch of winter oats with spring barley due to rabbit damage. The crop is growing well but rabbits remain a problem.

“It was a remarkably dry May,” says Rob, as just 22mm of rain fell last month. Conditions have been blustery and sunny which have been good for growth, but nighttime temperatures have been low. Over the past week, 25mm of rain has fallen and despite soil moistures at comfortable levels, the rain was welcome.

Crops are still very clean and look excellent. Rob recently sent away leaf samples of suspected BYDV for analysis as he questions whether crops were actually infected with the diseases or if they were just stressed. The crop received no aphicide and the seed wasn’t treated with Redigo Deter. He is now assessing the areas where sterile brome is present and which needs to be addressed through rotational changes.

The top three leaves are clean on around 85% of his winter wheat crops. His Cellule winter wheat has flowered and received a T3 of Prosaro (1.5l/ha). There is a small amount of steam mildew present.

His Graham wheat in particular was showing some yellow tipping, most likely as a result of stress due to cool nighttime temperatures. Some Septoria is creeping into his Costello on leaf three. The remainder of his crops are due a T3 head spray this week of Prosaro (1.2l/ha) and possibly Bravo (1l/ha).

His bean crop is very thick and he has adopted a preventative disease spray strategy to limit disease. He applied Dithane (1kg/ha) along with his weed spray (Stratus Ultra at 2l/ha). He will apply Dithane again in its T1 spray. The crop is currently beginning to flower.

Crops sown after the tine drill are more uneven when compared to those established with his disc drill. Weed pressure is also lower in the crops which were direct-drilled.

His spring barley crop remains clean. Some spring barley received Axial Pro (0.8l/ha) to target ryegrass on May 16. The crop received its T1 fungicide on 24 May of Proline (0.6/ha) Magnite (2.5l/ha) and Nova4 (1l/ha). He is currently planning his rotation for the 2020 cropping year and reviewing cover crop options.
