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.

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.

► 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

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.

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.

-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

Pear Leaf Blister Mite

► Sevin XLR Plus FLO 2.3 L Oil for Psylla control would also control blister mite.

Pear Psylla European Red Mite

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.
