New Movento EAMU* on Willow-carrot aphid, parsnip aphid, willow parsnip aphid and peach-potato aphid

The problem
Willow-carrot aphid principally over-winters as eggs on winter host and migrates onto carrot and parsnip for 5-6 weeks from May, peaking in early June. Following the recent warmer weather we’re seeing an increase in aphids across the UK and the willow-carrot aphid was caught at 11 sites this week (Source: AHDB Aphid News (13th May 2016 No.7)). With the high aphid pressure comes the accompanying threat of high levels of virus. In addition, carrot growers now have significantly limited choices following restrictions on the use of pirimicarb (Biscaya and pirimicarb having been the main controls to date).
Willow-carrot aphid can cause two kinds of problems:
1. Crop losses from direct feeding damage, usually at very early crop stages
Symptoms include discoloured, distorted leaves, ‘honeydew’ and discarded skins. Last year, many crops were lost completely to aphid damage, particularly in East Anglia.
2. Transmission of viruses
- Parsnip yellow fleck virus - severe damage, stunting and black cores
- Carrot Motley Dwarf Complex (Carrot red leaf virus and Carrot mottle virus) - reddening or yellow mottling of leaves and stunting
- Carrot yellow leaf virus (CYLV) - recently discovered by an AHDB-funded project led by FERA’s, Adrian Fox. CYLV is strongly linked to root necrosis and impossible to detect in the field. Growers reported up to 50% loss of their marketable yield due to necrosis issues last season. A further complication is that Peach-potato aphid (Myzus persicae) is now known to be a vector of CYLV too. Biscaya is the only foliar insecticide available that will control this aphid on carrots.
- Carrot torrado virus (CaTV) – newly discovered but its impact and incidence is unknown.
What to use:
Movento EAMU* 1305/2016
- EAMU for control of willow-carrot aphid, parsnip aphid, willow parsnip aphid and peach-potato aphid in carrot, parsnip, swede and turnip
- Apply Movento only when plants are actively growing and pests actively feeding
- Use rate: 0.3 L / ha
- Max no. of applications: 2 per crop
- Harvest interval: 8 weeks
Biscaya
- For control of Willow-carrot aphid in carrot and parsnip
- Spray Biscaya first when crop canopy is ‘open’
- Use rate: 0.4 L / ha
- Max no. of applications: 2 per crop
- Harvest interval: 7 days
- No LERAP
*This extension of the authorised use provides for the use of Movento in respect of crops and situations, other than those included on the product label. No efficacy or phytotoxicity data have been assessed and as such the ‘extension of use’ is at all times done at the user’s choosing, and the commercial risk is entirely theirs. Users are required to be in possession of the relevant Extension of Use details. Electronic copies of Extensions of Use can be obtained from the Chemicals Regulation Directorate (CRD) website https://secure.pesticides.gov.uk/offlabels
Understanding modes of action
- Movento works slowly over a period of days. Nymphs are most susceptible; and importantly the ability of adults to produce offspring is reduced. Its unique 2-way systemicity offers long-lasting protection but it is not a “knockdown” product. It works best when the plant is actively growing and when pests are actively feeding. It’s important to ensure that there is sufficient crop leaf area for the uptake of Movento.
- Biscaya acts on the pest’s nervous system and is effective even at lower temperatures. It works quickly, stopping feeding within hours – it can be used as a “knockdown” treatment.
What to do
Option 1: If a CNI seed treatment has not been used:
- At the first sign of aphids (normally during May / June) apply Biscaya at 0.4 L/ha. Crops at the cotyledon stage are most susceptible
- Follow with Movento
- Under high aphid pressure a max of 2 applications of Movento and Biscaya are permitted. Biscaya has a harvest interval of 7 days and Movento has an 8 week harvest interval
Option 1
Option 2: If a CNI seed treatment has been used (e.g. EAMU 0737/2016 70% w/w thiamethoxam):
- Apply Movento as the first subsequent foliar spray as it offers a different mode of action and is a non-neonicotinoid product
- Only 1 single foliar application of a neonicotinoid can then be used.
- Biscaya could be applied as the second foliar spray
