Publication 360 Coming Soon!

The 2016-2017 Publication 360, Guide to Fruit Production is anticipated to be available for growers mid-March 2016. This publication will have the latest information on pest management, crop nutrition, pesticide safety, and resistance management. New this year are reference tables including mating disruption products and plant growth regulators, a section on adjuvant options, a new specialty berry calendar, and new products added to the apple, berry, grape, tender fruit and tree nut calendar.

The 2015-2016 apple chapter includes updated tables for PHI/REI periods, product activity against insects, mites and disease, and toxicity of pesticides to beneficial insects. It also features additional pests or control timings in the apple calendar, such as alternaria blotch, fly speck, sooty blotch, San Jose scale, and fire blight.

The following new products for apples will be included in this publication:

Fullback 125 SC (flutriafol) is a Group 3 fungicide registered for control of scab at 950 mL/ha and powdery mildew, quince rust, and cedar apple rust at 585-877 mL/ha. For scab control begin application at half-inch green or when conditions are favourable for primary scab development. Continue application through the duration of primary scab season. Fullback should be tank-mixed with a compatible protectant fungicide to improve fruit scab control and for resistance management. For powdery mildew and rust begin application at green tip and continue through cover sprays. Do not use Fullback when sporulating lesions of the target disease are present.
Preharvest interval (PHI): 14 days;
Re-entry interval (REI): 12 hours;
Maximum applications per year: 2.05 L/ha

Sercadis (fluxapyroxad) is a Group 7 fungicide registered for control of apple and pear scab at 333 mL/ha and powdery mildew at 167-333 mL/ha. Begin coverage for these diseases at green tip and apply on a 7-14 day interval until full bloom if disease persists or weather conditions favour disease development. In conditions of rapid growth or high disease pressure use a high rate and shorten intervals between applications. For scab control, use with a non-ionic surfactant at a rate of 0.125 % v/v (1.25 L in 1,000 L).Do not use Sercadis when sporulating lesions of the target disease are present.
Preharvest interval (PHI): 0 days;
Re-entry interval (REI): 12 hours;
Maximum # of applications per year (on label): 4 (maximum 2 applications for resistance management).

Serenade OPTI (Bacillus subtilis) is a Group 44 biofungicide registered for the suppression of fire blight at 1.1-1.7 kg/ha and for suppression of apple and pear scab and powdery mildew at 1.7-3.3 kg/ha. For suppression of fire blight begin application at 1-5% bloom and repeat on a 7-10 day interval. For suppression of scab begin application at green tip or when conditions are favourable for primary scab development, and continue on a 7-10 day interval. For suppression of powdery mildew, begin application at tight cluster or earlier if conditions are conducive to disease development. Repeat applications on a 7-10 day interval.
Preharvest interval (PHI): 0 days
Re-entry interval (REI): when dry
Maximum # of applications per year (on label): N/A

Cueva (copper octanoate): is a Group M fungicide registered for control of fire blight and scab, using a 1% solution in 470-940 L water/ha (ex. 5L in 500 L water /ha). Cueva can be used to control fire blight through bloom and as an in-season cover spray to protect against trauma blight. For scab control begin coverage at green tip and re-apply on a 5-10 day interval as needed. Cueva may cause russeting of light coloured apple varieties. Use a 0.8% solution if fruit is present. If concerned about the sensitivity of fruit apply Cueva to individual trees or a small area and wait to determine if injury occurs prior to treatment of a larger area.
Preharvest interval (PHI): 1 day
Re-entry interval (REI): 4 hours
Maximum # of applications per year (on label): 10

Regalia Maxx (Reynoutria sachalinensis extract): is a biofungicide registered for suppression of powdery mildew, sooty blotch, fly speck, and bitter rot applied at 0.125% v/v in 1000L water/ha. Begin application preventatively at pink for suppression of powdery mildew and at petal fall for sooty blotch, fly speck and bitter rot, repeating applications on a 7-10 day interval. Petal fall applications can be increased to 0.125%- 0.25% v/v in 1000L water/ha. Continue applications on a 10-14 day interval depending on crop growth and disease pressure.
Preharvest interval (PHI): not specified
Re-entry interval (REI): when dry
Maximum # of applications per year (on label): not specified on the product label

Double Nickel (Bacillus amyloliquefaciens) is a Group 44 biofungicide registered for suppression of fire blight at 1.0-1.5 kg/ha. Apply at bloom. Under moderate to high disease pressure, or conditions that are conducive to disease development, use higher labelled rate, more frequent applications or rotate with other fungicides to improve performance. As this is a new product in Ontario little evidence of its efficacy is available. Test on a small scale before using it more broadly.
Preharvest interval (PHI): None
Re-entry interval (REI): when dry
Maximum # of applications per year (on label): not specified on the product label

Aprovia (benzovindiflupyr) is a Group 7 fungicide registered for control of scab at 300-500 mL/ha and powdery mildew and alternaria blotch at 500 mL/ha. Begin coverage for scab and powdery mildew at green tip, and petal fall for alternaria blotch control. In conditions of rapid growth or high disease pressure, use high rate and shorten intervals between applications. Tank-mix with a compatible protectant apple scab fungicide from a different group to improve control of fruit scab. Do not use Aprovia when sporulating lesions of the target disease are present. See label for suggested tank-mix products.
Preharvest interval (PHI): 30 days
Re-entry interval (REI): 12 hours
Maximum # of applications per year (on label): 2 L/ha

Mako (cypermethrin) is a group 3 insecticide replacing Ripcord. Mako is registered for the same pests and timing as Ripcord.
Preharvest interval (PHI): 7 days
Re-entry interval (REI): 12 hours
Maximum # of applications per year (on label): 2

Xiameter OFX-0309 is a silicone surfactant replacing Sylgard 309. Add Xiameter to Retain at a rate of 0.05%-0.1% by volume to improve spray coverage and enhance absorption.

Reminder: due to the decision by the Pest Management Regulatory Agency (PMRA) to phase-out diazinon insecticides, Diazinon 500 E (PCP # 11889) and Diazinon 50 WSP (PCP # 29976) will no longer be permitted for use on apple after December 31, 2016. Diazinon products can be used until December 31, 2016, provided changes to the label are followed. Do not use in 2017.
