5430062	sulfentrazone		Damage from herbicide, Sulfentrazone The leaves show two primary symptoms:1- areas or blotches of necrotic tissue that is due to splashing of “Spartan” up onto the leaf. It is associated with highrates of the herbicide (or overlapping), wet prone soils, and/or a heavy rain preceding the onset of symptoms by a few days. 2- a death (whitening) of the finer veins and a little puckering. This can be associated with the herbicide "Spartan" when taken up through the roots. The injury is associated with movement of the herbicide into the root zone due to incorporation and/or a heavy rain preceding the onset of symptoms by a few days. These symptoms are usually seenon the older leaves and little or no symptoms on the younger ones. The plants will usually grow out of the injury sustained earlier in the season. Plants taking up enough herbicide to cause injury later in the season will be stunted and the leaves that are injured are not marketable.

5430045	sulfentrazone		herbicide damage of Sulfentrazone The leaves show two primary symptoms:1- areas or blotches of necrotic tissue that is due to splashing of “Spartan” up onto the leaf. It is associated with highrates of the herbicide (or overlapping), wet prone soils, and/or a heavy rain preceding the onset of symptoms by a few days. 2- a death (whitening) of the finer veins and a little puckering. This can be associated with the herbicide "Spartan" when taken up through the roots. The injury is associated with movement of the herbicide into the root zone due to incorporation and/or a heavy rain preceding the onset of symptoms by a few days. These symptoms are usually seenon the older leaves and little or no symptoms on the younger ones. The plants will usually grow out of the injury sustained earlier in the season. Plants taking up enough herbicide to cause injury later in the season will be stunted and the leaves that are injured are not marketable.

The spots are often concentrated along the side of the midrib and large secondary veins but can be found anywhere on the leaf. On expanding leaves the spots appear near the tip. Lower leaf surfaces may show no evidence of damage in the early stages. Lesions may run together causing the leaf surface to become necrotic and fall out.

5369003	leaf distortion		Leaves showed white tissue in areas on the margins and areas of white flecking located symmetrically on the leaves. A representative from Yoder Bros. said they call this the "Lisa problem". Yoder has done extensive virus/viroid testing over time and we have never been able to associate a virus or viroid. Likewise, they have done foliar and soil analyses and not been able to associate anything consistently. Also, they have never been able to associate spray injury, etc. Yoder sees this on 'Lisa' usually in the heat of the summer. The sunken white flecks are not apparent in cooler temperatures. Usually the crop grows out of it. After several years, this flecking symptom has not been considered a major problem for the chrysanthemum crop.

5368774	herbicides (general)		The leaves show two primary symptoms:1- areas or blotches of necrotic tissue that is due to splashing of “Spartan” up onto the leaf. It is associated with highrates of the herbicide (or overlapping), wet prone soils, and/or a heavy rain preceding the onset of symptoms by a few days. These symptoms are usually seenon the older leaves and little or no symptoms on the younger ones. The plants will usually grow out of the injury sustained earlier in the season. Plants taking up enough herbicide to cause injury later in the season will be stunted and the leaves that are injured are not marketable.
5368864	weather fleck		Dark tobacco. Note "ring spot" on the leaves. This “ring spot” (also known as "star and crescent spot") which has the form of a necrotic spot encircled by alternating rings of healthy and injured tissue, with the necrotic rings being partial rings or broken lines, is described in an Agronomy Journal of 1971 as physiological in cause (not being caused by a pathogen, air pollutant, nutrient, or chemical). The book "Diseases of Tobacco" 3rd edition, puts this "ring spot" and the reference that says it is not caused by an air pollutant, under the category of weather flecking.We have sent similar samples in the past to a private laboratory for a tobacco virus screen and they have always come back with negative results.

5368914	weather fleck		The spots usually start as small dark green water-soaked areas. Within 48 hours, the lesions change to a brown color then to a gray or white and appear as sunken necrotic areas bordered by chlorotic tissue (on dark tobacco you usually do not see any yellow halo). The spots are often concentrated along the side of the midrib and large secondary veins but can be found anywhere on the leaf. On expanding leaves the spots appear near the tip. Lower leaf surfaces may show no evidence of damage in the early stages. Lesions may run together causing the leaf surface to become necrotic and fall out. Symptoms may occur at any growth stage, but most commonly occur during periods of rapid growth. Older leaves are more susceptible. Dark fired types usually show less injury than burley types when at the same growth stage and exposed to the same level of ozone.

5368978	catfacing		Symptoms at stem end. Catfacing symptoms are associated with adverse growing conditions during blossoming; the adverse conditions result in poor pollination, which leads to irregularly shaped fruit. Catface symptoms are most often seen in large-fruited, fresh market varieties (although other varieties can also be affected) and are associated with disturbances in flower production such as low temperature injury 3 weeks before flowers are mature, especially in early plantings, but also with injury from growth regulators such as 2,4-d. Pruning and high nitrogen can also aggravate the problem.
