Emergency and First Aid Procedure for Pesticide Poisoning
·
Become familiar with the chemicals you are using. Keep a list of common and active
ingredient names in case of accidents or emergencies. This information can be found on
product labels and cross-referenced in this publication.
·
If a pesticide has come in contact with the skin or has been spilled on clothing, remove
the clothing and wash the skin thoroughly with soap and warm water.
·
If poisoning from exposure to a pesticide by swallowing, inhalation or contact with skin
or eyes, is suspected read the label of the pesticide container if available and carry out
first aid treatment as suggested.
·
Immediately after first aid treatment has been given, wrap the patient in a coat or blanket
and rush him/her to the nearest hospital. Take the list of chemical common names with
you and identify the one being used.
·
If a person is unconscious or lapses into unconsciousness, call
911
immediately.
·
Emergency advice on pesticide poisoning is available from the Poison Information

PESTICIDES LISTED IN THIS SCHEDULE
This listing includes all the registered pesticides (excluding herbicides) detailed in the Apple and Pear Orchard Management Schedules. Some of the secondary insects and diseases referred to on the pesticide labels are also listed, but caution must be used in interpreting the effects on these secondary pests. The Schedule recommends the timing of application based on the target pest which is often not the appropriate time for control of the secondary pests.

Apple Orchard Management Schedule for Nova Scotia 2013/2014
A guide to insect, mite and disease management in apple orchards
-
All rates are per hectare of mature (“standard”) trees or full dilute volume of about 3370 litres of water /ha. To adjust for smaller trees and higher density plantings, refer to Tree Row Volume factsheet TF 92002 or Integrated Fruit Production Guide.-All rates are based on label rates. In some cases, reduced rates can be used based on factors other than tree size. Please refer to specific notes or your agricultural advisor for details. -Always read the label before using any pesticide. Where differences between the label and this schedule occur, label information prevails.
Disease and Insects Products Formulation Rate per ha Notes
GREEN TIP
Apple Scab Use one of the following listed fungicides. ► Maestro Supra Captan 80 DF 80 WDG
3.75 kg Do not mix with oil or strongly alkaline materials. Do not use 7 days before or after an oil application. Early season sprays may cause injury to the foliage of Red Delicious.
► Dithane Manzate 200 Penncozeb 75 DG 75 DF 75 DF
6.00 kg Compatible with oil.
► Polyram 80 DF 6.00 kg Compatible with oil. Do not mix with liquid fertilizer or hydrated lime.
► Allegro 500 F 0.75-1.0 L Make no more than 3 sequential applications before alternating with a fungicide belonging to alternate chemical family. Make no
more than 9 applications per year. Apply with a minimum of 1000 liters of water. Use higher rate for heavy disease pressure and on more susceptible cultivars.
► Scala SC 0.75-1.0 L Apply at 7-12 day intervals from green tip to petal fall. Do not apply post bloom. Do not apply more than 6.0 L per hectare or
more than 4 applications in a row. Apply in a minimum spray volume of 1000 L/ha.
► Vangard 75 WG 370 g Apply as a protectant spray on a 7 to 10 day schedule. Do not apply more than 2 applications alone. Do not apply more than 6
times per season. Do not apply more than 1.5 kg/ha of Vangard per season. Avoid drift onto cherries. For added protection and resistance management tank mix with one of the following: Polyram DF, Manzate 200 DF or Dithane DG at full rate.
► Equal/Syllit 65 WP 1.08-2.25 kg Compatible with oil. Use high rate for high disease pressure and low rate for low disease pressure. For missed infection periods, apply 3.25 kg/ha within 36 hours of infection period start. Restrict use to avoid scab resistance, alternate with other fungicides that are not in group M7.
► Senator + Captan 70 WP 80 WP 625 g 2.00 kg
Must be used as a mixture to avoid scab resistance. Do not mix with lime or other alkaline materials. Do not mix the Captan mixture with oil or apply 7 days before or after an oil application. If Benomyl resistance has been detected this product may be ineffective.
European Red Mite Assess winter eggs on twigs and bark, refer to Pest Management Fact Sheet #6 or Best Management Practices for NS Apple Production. http://perennia.ca/fruit.php ► Superior Oil
Purespray Green Spray Oil
70 sec 13 E
65 L 65 L
Best results are obtained when applied with a high volume of water 1500 to 3370 L/ha. Do not apply oil during freezing temperatures or just following a frost. Check compatibility with fungicide. May cause bark injury on Red Delicious and Empire.
15 mm GREEN to TIGHT CLUSTER
Apple Scab Use a fungicide as listed under Green Tip. Check fungicide compatibility with oil treatments for mites.
Powdery Mildew If mildew was a problem during the previous growing season select an appropriate fungicide listed below. In most cases mildew treatment should begin around the tight cluster stage of bud development. Under extreme mildew pressure treatments can begin earlier. General fungicide treatments for powdery mildew will also control apple scab.
Tight Cluster-Bud Separation

Disease and Insects Products Formulation Rate per ha Notes
Powdery Mildew ► Sovran 50 WG 240-450 g Do not make more than 2 sequential applications or more than 4 applications per year of Sovran or Flint then alternate with 2 applications of a fungicide with a different mode of action. Apply at 10 to14 day intervals using the shorter interval for periods of rapid shoot growth. Use the 240 g rate for low to moderate disease pressure and 450 g for high to extreme disease pressure.
► Flint 50 WG 140-210 g Do not apply more than 2 sequential applications of Flint or Sovran. Do not apply more than 4 times per season.
► Pristine WG 1.0-1.2 kg Do not apply more than 4 times per year. Use high rate under high disease pressure.
► Fontelis S 1-1.5 L Use high rate when disease pressure is high. Make no more than 2 sequential applications before switching to a fungicide of a
different chemical family. Maximum seasonal use rate 4.5 L.
► Luna Tranquility SC 600 mL Apply with a minimum water volume of 500 L/ha. Do not exceed 4 applications or 3.2 L/ha/season. Do not make more than 2
sequential applications. Will also control apple scab when used at a rate of 800 mL/ha.
► Microscopic Sulphur Kumulus 92 G DF 19.50 kg 22.50 kg
Do not apply within 30 days of an oil treatment. Do not apply if high temperatures (26º C+) and humidity prevail or are expected during the three days following application. Do not use on Delicious. Usage may result in elevated populations of red mite and scale.
Winter Moth Assess larvae at this stage and refer to Pest Management Fact Sheet #8 or Best Management Practices for NS Apple Production. http://perennia.ca/fruit.php
Spotted Tentiform
Leafminer Assess adult activity at this time and refer to Pest Management Fact Sheet # 21. http://perennia.ca/fruit.php
European Red Mite Assess winter eggs on twigs and bark. Refer to Pest Management Fact Sheet #6 or Best Management Practices for NS Apple Production. http://perennia.ca/fruit.php
► Superior Oil Purespray Green Spray Oil

65 L 65 L
Best results are obtained when applied with a high volume of water 1,500 to 3,370 L/ha. Do not apply oil during freezing temperatures or just following a frost. Check compatibility with fungicide. May cause bark injury on Red Delicious and Empire.
Solupacks-Many pesticides have been packed into solupacks, but beware that these may not dissolve properly in the presence of oil, boron or chlorine in the spray tank.
BUD SEPARATION
Apple Scab Use one of the following listed fungicides.
► Allegro 500F 0.75-1.0 L Make no more than 3 sequential applications before alternating with a fungicide belonging to alternate chemical family. Make no

Start checking in early April when day time temperatures are near 10ºC for the presence of adults and egg laying activity ► ► Superior Oil Purespray Green Spray Oil 70 sec 13 E 65 L 65 L
Apply late dormant season when first adults are observed on a sunny day. Good coverage is essential; use a minimum of 1000 L of water per hectare. 3000 L of water will provide the best results. Check 10 to 14 days following treatment for signs of new egg laying and the need to apply a second treatment. Pear leaf blister mite would also be controlled.
