A new Verimark label has been issued. There is one change on it - 'Verimark cannot be applied after 31 August' - but this only applies to the UK. Take note that the maximum total dose is 600 ml/ha which is equivalent to 40,000 brassica plants per ha. Verimark 20SC (2018 label)

Iprodione (Rovral WG, Grisu) has been deregistered with a sell-by period to 5 March 2018 and a use-by to 5 June 2018. The sell- and use-by periods have recently been significantly reduced by the the EU - it used to be a 6 month sell-by period followed by a 12 month use-by period; now it's down to 3 + 3 months. Iprodione decision

The old Butisan label (PCS 90342) was deregistered 31 March 2017 and there is one significant change on the new label (PCS 04631). The rate for broccoli is reduced from 1.5 l/ha to 1.0 l/ha; all other crops remain the same. However the old label has a use-up period to 30 September 2018. Butisan S (04631)
8 December 2017
Venzar Flowable will be deregistered on 31 March 2018 with a use-up period to 30 September 2019 - currently there is an off-label for that product for spinach and spinach beet. Venzar Flowable will be replaced by Venzar 500 SC which was registered last week. There is a new off-label on the 500 version that not only covers the old crops of spinach and spinach beet but also adds in chard, beetroot, celeriac, swede and turnip. Take note that the rate for spinach has been reduced to 0.8 l/ha, which is quite a drop on the old rate. The other thing to be aware of is that it can be applied only once every three years to any one piece of land. However the old Venzar Flowable off-label is good to 30 September 2019. Venzar 500 off-label Venzar 500 SC

A much-awaited qualified majority of EU member states was reached today for the re-authorisation of the world’s most commonly used weedkiller, glyphosate. It was granted a five year re-approval which is a considerable reduction in the original proposal of granting a 15 year re-approval.
Signum off-labels have been updated covering both food and ornamentals.
Food - outdoor: red and white currants, blueberry, gooseberry, salad onion, parsnip, celeriac, courgette, summer squash and horseradish; outdoor and indoor: herbs, cherry, plum, babyleaf lettuce and brassica. Signum food off-label
Ornamentals - outdoor and indoor: foliage, flowers, woody ornamentals, ornamental seedlings and bulbs and forest nursery. Signum ornamentals off-label

The European Commission host a very useful website that allows you to find the current MRL (maximim residue limit) for any particular crop. For example, you can run a search for the MRL for azoxystrobin (Amistar) on cabbage and broccoli. MRL's have been set for all actives and represent the maximum residue that should arise in food when pesticides are correctly used. MRL figures for any particular pesticide and crop combination can and do change - so keep an eye on them using this database.

The Farm Hazardous Waste Collection Days 2017 will be taking place during October/November. There are 10 locations around the country. These EPA funded collection points allow farmers to get rid of hazardous materials at a very reduced rate - €2 per kilo. Please consult the flier for details: Hazardous Waste Leaflet
21 September 2017
It is expected that the authorisation of all iprodione products (Rovral WG, Grisu) will be revoked in the next few months. It will shortly be voted on by Brussels. So we should have the use of the active for the next two seasons.
4 September 2017
All products based on cypermethrin were deregistered 31 March 2017 with a final use-up date of 30 September 2018. During the course of a review of cypermethrin, a minimum buffer zone requirement of at least 85m was proposed for products containing this active. Taking into account the average field size and prevalence of water courses in Ireland and as the PCS currently have a policy of not approving products which require buffer zones (aquatic or non-aquatic) that are in excess of 50m, a decision was taken not to renew the approval for field use. Cypermethrin based products include: Ambush, Barclay Cypersect, Croplink Methrin, Sitrine. The active is still available on the amateur market.
The long awaited new aphicide from Dow is now registered as Closer, which contains sulfoxaflor. The label covers use on brassicas, lettuce, spinach and potatoes. It's available as Transform for cereals. This is a brand new systemic active that promises to be a useful replacement for Aphox. Closer label

Luna Privelege was granted a 120 day authorisation for protected cucumbers which started on 1 June 2017. There is one change to the original version: "grown in artificial substrate" has been added to the crops.
Luna Privilege Authorisation.
Talius is a new off-label for the control of powdery mildew in outdoor ornamentals and forest nurseries.
17 July, 2017
Benevia has been recently approved by the PCS. It's the foliar version of Verimark (cyantraniliprole). It has on-label approval for use on cabbage, cauliflower, broccoli, Brussels sprouts, onions, scallions, carrot and parsnip. It controls cabbage root fly (CRF) and caterpillar on brassicas, thrips and onion fly on alliums and carrot fly on carrot and parsnip. There is also an off-label for Benevia to control CRF and caterpillar on swedes and turnips. Benevia off-label

Cuprene 50 (copper oxychloride) that was deregistered on 31 December 2014 has resurfaced in the form of Curenox 50WP which is distributed by Unichem. It has has grapes on the label with an off-label for potato, swede, apple, pear and ornamentals. It arose from pressure from French grape farmers to get some form of copper reinstated and the Department here were anxious to have something that organic growers could use for potato blight as currently there is nothing. The off-label covers blight on potatoes, downy mildew on swede and scab and canker control on apple and pear. An effort was made to get one of the systemic blight products in as an off-label for downy mildew control on swede but it didn't work out. Curenox 50WP off-label
14 June, 2017
A great new blight fungicide has been launched by DuPont: Zorvec Enicade (oxathiapiprolin). It's been on trial in Oak Park for the past two seasons and has performed well. Plus the even better news is that onions are on the label along with garlic and shallots. BUT......here's the problem. The label states that it can only be used as a tank mix with Curzate (for resistance management purposes) which is fine for potatoes as Curzate is registered for that crop but onions are not on the Curzate label. So Zorvec will be a no-show for alliums.
3 April, 2017
A 120 Day Authorisation has been granted for the use of Luna Privilege on indoor tomatoes grown in artificial substrate for the control of Cladosporium. It runs from 1 April to 29 July 2017.

The Score label has been reregistered. A small but important change in the re-issued label is that the maximum number of applications has been cut from 3 to 2 in cabbage and from 4 to 2 in Brussels sprouts. A revised off-label for Score has added outdoor lettuce to the existing list of crops. This is a welcome addition that will help in the control of lettuce leaf spot.
28 March 2017
A new herbicide Bonalan, has recently been registered for use on a range of vegetables with both on-label and off-label recommendations. It's based on an active called benfluralin closely related to trifluralin that was in Treflan of old. However in comparison to Treflan it covers a smaller spectrum of weeds and will be more expensive. It controls fat hen, Polygonums and annual meadow grass. On-label crops include cabbage, cauliflower, broccoli, sprouts, peas, beans and lettuce and off-label crops cover swede, baby leaf, herbs and spinach. Bonalan off-label
14 March 2017
A new off-label for disease control in ornamental bulbs has been launched - Deuce.
