New products registered for berry crops in 2013
The new 2013 Supplement to Publication 360, Guide to Fruit Production, will be available shortly online or from your local OMAF and MRA Resource Centre. In the meantime, here are the new products for berry crops that will be included in this publication:
- Actara 25 WG (thiamethoxam) is a Group 4 insecticide registered for black vine weevil adults on strawberries. Do not apply until after bloom. Highly toxic to bees. Pre-harvest interval (PHI): 3 days
- Admire 240 F (imidacloprid) is a Group 4 insecticide
with many new uses on the label. It can be used as a foliar spray
on blueberries for control of aphids, blueberry maggot, Japanese
beetle adults, or suppression of leafhoppers, and for control
of aphids and suppression of leafhoppers on strawberries, currants,
gooseberries, saskatoon berries, elderberries and many of the
other crops in the bushberry crop group 13B. Admire can also be
applied as a soil application for control of aphids and suppression
of white grubs in strawberries. PHI: depends on use pattern and
crop. Read the label carefully.
- Do not use both a soil application and a foliar application of Admire, or any other group 4 insecticide, in the same year.
- Do not spray during the bud or bloom stage or when bees are actively foraging. Highly toxic to bees.
- Altacor (chlorantraniliprole) is a Group 28 insecticide registered on the bushberry crop group (blueberries, currants, elderberries, saskatoon berries) for control of cranberry fruitworm, cherry fruitworm, obliquebanded leafroller, blueberry spanworm, and for suppression of Japanese beetle. PHI : 1 day
- Matador 120 EC and Silencer 120 EC (lambda-cyhalothrin) are Group 3 insecticides registered for black vine weevil control in strawberries. These products are effective at knocking down adult weevils after harvest, but like all insecticides in group 3 (pyrethroids), they break down more quickly and may be less effective at high temperatures (over 27C). Pyrethroids are also very toxic to bees and to predators of cyclamen mites and two-spotted spider mites. PHI: 7 days
- Pyganic Crop Protection EC 1.4 II is a Group 3 insecticide registered on blueberries and raspberries for aphid and leafhopper control. Pyganic has very short residual activity, breaks down quickly in sunlight and is highly toxic to bees. May be approved for some organic production systems. Check with your organic certifier. PHI: 12 hours
- Warhawk 480 EC (chlorpyrifos) is Group 1B insecticide registered for cutworm control in strawberries, so useful in the planting year. This is a new registration of an older, organophosphate product, also highly toxic to bees. PHI: 20 days
- Flint Fungicide (trifloxystrobin) is a group 11 fungicide registered for powdery mildew control on strawberries. This product is in the same fungicide group as Pristine and Cabrio. Do not rotate with these products. PHI: 0 days.
- Fontelis (penthiopyrad) is a Group 7 fungicide registered on strawberries for the control of botrytis grey mould. Fontelis is in the same fungicide group as Cantus, Lance and Pristine. Do not rotate with these products. PHI: 0 days
- MustGrow Crop Biofumigant (oriental mustard seed meal) is a biofumigant, formulated as pellets, registered for suppression of red stele and root lesion nematode in strawberries and suppression of phytophthora root rot and root lesion nematode in raspberries. Apply with a calibrated spreader, in early spring when soil temperatures are above 10 C, but at least 2 weeks before planting. Incorporate into the upper soil layer to a depth of 10-15 cm, followed by irrigation to ensure the top 10-15 cm of soil is well moistened.
- Phostrol fungicide (mono and dibasic sodium, potassium and ammonium phosphites) is a Group 33 fungicide, registered for suppression of phytophthora root rot on raspberries and control of leather rot on strawberries. PHI: 1 day on raspberries and 3 days on strawberries.
- Quadris Flowable Fungicide is a Group 11 fungicide registered for suppression of black root rot on strawberries in the year of planting. Apply once in-furrow at planting or a banded drench application immediately after planting to up to 8 days after planting. The pre-harvest interval is 365+ days, so do not use this on day-neutrals.
- Quash Fungicide is a Group 3 fungicide registered for control of mummyberry, anthracnose and phomopsis control on blueberries. Quash is in the same fungicide group as Topas, Mission, Jade and Funginex, but has a shorter preharvest interval. PHI: 12 days.
- Regalia Maxx (extract of Reynoutria sachalinensis) is a biofungicide registered for suppression of powdery mildew on strawberries. There is little or no experience with this product in Ontario. Test on a small scale before using more broadly. Regalia Maxx works by stimulating plant defence mechanisms. It works best if applied before there is disease present. Repeat applications at 7-10 day intervals. Use this product in rotation with conventional fungicides. PHI: 0 days
- Tivano (citric acid + lactic acid) is a biofungicide registered for suppression of angular leaf spot and powdery mildew on strawberries. There is little or no experience with this product in Ontario. Test on a small scale before using more broadly. Multiple applications at 7-10 day intervals are required for control. PHI: not specified on label.
