New, updated Syngenta cereal apps being launched to aid autumn decisions

Product Update

Two free, new, updated apps designed to help cereal growers and advisors with key autumn agronomy decisions are being launched by Syngenta.


The Hybrid Barley Calculator app, originally unveiled two years ago, helps users assess the potential return on investment from growing hybrid barley versus a conventional winter barley. Users simply select the varieties to compare and their grain price per tonne, and factor in other variables, such as the value of any extra black-grass suppression from a hybrid, as seen in trials.


The new updated version now also allows users to factor in any extra income from barley straw, says Syngenta hybrid barley portfolio manager, Mark Bullen, and to adjust the price paid for their conventional winter barley seed.


“Clearly, straw is a valuable source of extra income for some barley growers,” says Mr Bullen, “so we wanted to include this as part of the new, updated app features. Users simply select the price they receive per tonne of straw on a sliding scale.


“Similarly, the price paid per tonne of conventional barley seed can vary, so we wanted users to be able to factor that into the app. Ultimately, the aim is to provide a simple-to-use, informative tool to aid winter barley decisions.”


With prospects of a larger winter cereal area and earlier planting this autumn, a second newly-updated Syngenta app could also prove an invaluable tool for the coming season, says Syngenta technical manager for insecticides and sustainability, Dr Max Newbert.


BYDV Assist, first unveiled last season, is designed to help improve timeliness of spraying against aphid vectors of barley yellow dwarf virus (BYDV). This is based on cumulative daily temperatures reaching or nearing a threshold of 170 day degrees from crop establishment, says Dr Newbert, the point when second generation aphids typically move into the crop spreading the virus.


“With early protection from a neonicotinoid insecticide seed treatment no longer an option, timely aphicide application against second generation aphids has taken on added significance,” says Dr Newbert, “especially if cereals are drilled early, which increases aphid risk.


“With this in mind, we have improved the number of ways users can now receive aphid threshold alerts. As well as mobile phone alerts, users can now also receive alerts via e-mail to aid timely spraying, and can log on to access their aphid risk information for individual fields across different devices.


“By providing alerts to go out and inspect crops to monitor aphid numbers, the aim of the app is to help users narrow down the best time to spray and avoid over-use of aphicides,” Dr Newbert adds.


Both new apps are available free from The App Store and Google Play. Further information at and
