Cereals Live: Hybrid barley and BYDV apps updated

Syngenta has updated its Hybrid Barley calculator. Growers can now use their own seed price rather than using a standard price.

A straw slider has also been added in recognition of straw being a valuable source of additional income, said Mark Bullen of Syngenta. “At a yield of 6 tonnes/hectare of straw from hybrid barley, even at a price of £50/t it can be worth £300/ha for just the straw.”

 

The company has also updated its BYDV Assist app, explained Dr Max Newbert. “This year, to ensure they have crops in the ground, growers are likely to be drilling earlier. September to November is the risk period, especially up to mid-October. If earlier, you could hit the peak of aphids and seven to 42 per cent could be carrying the virus. There is also a very serious RPV strain emerging.”

 

Spray timing

 

BYDV Assist uses cumulative temperature data to alert growers to the optimum time to spray insecticides for aphid control.

 

“The app is still free but we now ask people to sign in, providing their name and email address. If you swap phones or log in on a different one data will be saved on the server so you can log back in to get the information.

 

“It is also now simpler to add in field details. Once you have entered field details you can go back in and edit fields without having to start again. At 40 day degrees, growers are given a warning that the 170 day degree spray threshold is likely to be reached in the next few days.”
