Universal Citation: ID Admin Code 02.02.02.130
Current through September 2, 2024
01. Injury. Any specific defect defined in this subsection or an equally objectionable variation of any one (1) of these defects, any other defect, or any combination of defects, that more than slightly detracts from the appearance or the edible or shipping quality of the apple. The following specific defects are considered as injury:
a. Russeting in the stem cavity or calyx basin that cannot be seen when the apple is placed stem end or calyx end down on a flat surface, is not considered in determining whether or not an apple is injured by russeting. Smooth net-like russeting outside of the stem cavity or calyx basin is considered as injury when an aggregate area of more than ten percent (10%) of the surface is covered, and the color of the russeting shows no very pronounced contrast with the background color of the apple, or lesser amounts of more conspicuous net-like russeting when the appearance is affected to a greater extent than the above amount permitted.
b. Sunburn or sprayburn, when the discolored area does not blend into the normal color of the fruit.
c. Dark brown or black limb rubs that affect a total area of more than one-fourth (1/4) inch in diameter, except that light brown limb rubs of a russet character are considered under the definition of injury by russeting. The area refers to that area of a circle of the specified diameter.
d. Hail marks, drought spots, other similar depressions or scars.
i. When the skin is broken, whether healed or unhealed;
ii. When there is appreciable discoloration of the surface;
iii. When any surface indentation exceeds one-sixteenth (1/16) inch in depth;
iv. When any surface indentation exceeds one-eighth inch (1/8) in diameter; or
v. When the aggregate affected area of such spots exceeds one-half (1/2) inch in diameter. The area refers to that of a circle of the specified diameter.
e. Disease.
i. Cedar rust infection that affects a total area of more than three-sixteenths (3/16) inch in diameter. The area refers to that of a circle of the specified diameter.
ii. Sooty blotch or fly speck that is thinly scattered over more than five percent (5%) of the surface, or dark, heavily concentrated spots that affect an area of more than one-fourth (1/4) inch in diameter. The area refers to that of a circle of the specified diameter.
iii. Red skin spots that are thinly scattered over more than one-tenth (1/10) of the surface, or dark, heavily concentrated spots that affect an area of more than one-fourth (1/4) inch in diameter.
f. Insects.
i. Any healed sting or healed stings that affect a total area of more than one-eighth (1/8) inch in diameter including any encircling discolored rings. The area refers to that of a circle of the specified diameter.
ii. Worm holes.
02. Damage. Any specific defect defined in this subsection or an equally objectionable variation of any one of these defects, any other defect, or any combination of defects, that materially detracts from the appearance, or the edible or shipping quality of the apple. The following specific defects are considered damage:
a. Russeting in the stem cavity or calyx basin that cannot be seen when the apple is placed stem end or calyx end down on a flat surface, is not considered in determining whether or not an apple is damaged by russeting, except that excessively rough or bark-like russeting in the stem cavity or calyx basin shall be considered as damage when the appearance of the apple is materially affected. The following types and amounts of russeting outside of the stem cavity or calyx basin are considered as damage:
i. Russeting that is excessively rough on Roxbury Russet and other similar varieties.
ii. Smooth net-like russeting, when an aggregate area of more than fifteen percent (15%) of the surface is covered, and the color of the russeting shows no very pronounced contrast with the background color of the apple, or lesser amounts of more conspicuous net-like russeting when the appearance is affected to a greater extent than the above amount permitted.
iii. Smooth solid russeting, when an aggregate area of more than five percent (5%) of the surface is covered, and the pattern and color of the russeting shows no very pronounced contrast with the background color of the apple, or lesser amounts of more conspicuous solid russeting when the appearances affected to a greater extent than the above amount permitted.
iv. Slightly rough russeting that covers an aggregate area of more than one-half (1/2) inch in diameter.
v. Rough russeting that covers an aggregate area of more than one-fourth (1/4) inch in diameter.
b. Sunburn or sprayburn that has caused blistering or cracking of the skin, or when the discolored area does not blend into the normal color of the fruit unless the injury can be classed as russeting.
c. Limb rubs that affect a total area of more than one-half (1/2) inch in diameter, except that light brown limb rubs of a russet character are considered under the definition of damage by russeting.
d. Hail marks, drought spots, other similar depressions or scars.
i. When any unhealed mark is present;
ii. When any surface indentation exceeds one-eighth (1/8) inch in depth;
iii. When the skin has not been broken and the aggregate affected area exceeds one-half (1/2) inch in diameter. The area refers to that of a circle of the specified diameter; or
iv. When the skin has been broken and well healed, and the aggregate affected area exceeds one-fourth (1/4) inch in diameter.
e. Stem or calyx cracks that are not well healed, or well healed stem or calyx cracks that exceed an aggregate length of one-fourth (1/4) inch.
f. Invisible water core existing around the core and extending to water core in the vascular bundles; or surrounding the vascular bundles when the affected area surrounding three (3) or more vascular bundles meet or coalesce; or existing in more than slight degree outside the circular area formed by the vascular bundles.
g. Disease.
i. Scab spots that affects a total area of more than one-fourth (1/4) inch in diameter. The area refers to that of a circle of the specified diameter.
ii. Cedar rust infection that affects a total area of more than one-fourth (1/4) inch in diameter. The area refers to that of a circle of the specified diameter.
iii. Sooty blotch or fly speck that is thinly scattered over more than one-tenth (1/10) of the surface, or dark, heavily concentrated spots that affect an area of more than one-half (1/2) inch in diameter. The area refers to that of a circle of the specified diameter.
iv. Red skin spots that are thinly scattered over more than one-tenth (1/10) of the surface, or dark, heavily concentrated spots that affect an area of more than one-half (1/2) inch in diameter. The area refers to that of a circle of the specified diameter.
h. Insects.
i. Any healed sting or healed stings that affect a total area of more than three-sixteenths (3/16) inch in diameter including any encircling discolored rings. The area refers to that of a circle of the specified diameter.
