There is a new label for Pyrethrum 5EC – which unfortunately has far fewer crops on it than the old label – essentially confined to a small range of protected crops: tomato, pepper, aubergine, courgette and cucumber. However growers have until 30 June 2020 to use up old label (PCS 92317) stocks which will be on sale until 30 June 2019.
22 January 2019
Closer, which is registered for use as an aphicide on cabbage, broccoli, Brussels sprouts, spinach and outdoor lettuce is currently unavailable. Stock may be available later in the season.

Decis (deltamethrin) has been reformulated and is now called Decis Protech. The new product is lower strength in comparision to the old. There are no stocks left of Decis and it will be deregistered shortly. There is a new off-label for the Protech version. A wide range of crops is covered by the on- and off-labels so please consult the relevant document for details. Good to see that both broccoli and lettuce are included on the labels.

Slug pellets based on methaldehyde are to be banned for outdoor use in the UK from the spring of 2020. They will still be allowed to be used in protected crops. It is being withdrawn because of a threath to wildlife and birds. The PCS are currently reviewing the situation for this country.

Two new off-labels for Emerger: food crops and ornamentals. Emerger is a herbicide that contains a new active for the country, aclonifen. This hopefully will work out to be a useful replacement for linuron. Outdoor forest nursery and willow are the ornamental crops covered. Food crops include parsnip, carrot, parsley, onion and garlic. Emerger OLA (ornamentals) Emerger OLA

Two old off-labels have been rereleased following the reregistration of the products. Nativo has retained parsnip on the off-label and added in celery, salad onion and swede; leeks have been dropped from the full label but reinstated via the off-label. The most significant change on the Nativo off-label is the use on celery for leaf spot control - important addition given we only had Score and Switch prior to this. Movento has retained all the old uses and added in protected: tomato, aubergine, cucumber, pepper, melon and courgette. Take note changes in rate and harvest interval with both products on some crops. Nativo off-label, Movento off-label

Cruiser, available as a seed dressing or via phyto-drip treated modules can no longer be be used after 19 December 2018.
On a more positive note an interesting new fungicide was launched by BASF in the UK this year - Perseus - and it will be registered here in 2019. It's a combination of Score + fluxapyroxad, a SDHI type active for use on a wide range of vegetable crops. Perseus UK label

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

27 November 2017
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

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.

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.

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.

6 July, 2017
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
