Cherry leaves

Under special conditions, such as hot weather followed by a freeze and drought, cyanogenic compounds can accumulate in cherry leaves. Caterpillars such as the Eastern tent czterpi hr,Malacosoma americanum, concentrate the toxic substances further in their bodies. Finally livestock inadvertently ingest their feces and carcasses on pastures or from water tanks. In 2001, this resulted in over... 

A composition of balsam ingredients is disclosed. It contains color, natural honey, milk, nut infusion, nut aromatic alcohol, sugar, Jerusalem artichoke infusion, black choke-berry juice, ashberry juice, St. John s wort, blackcurrant leaves, cherry leaves, echinacea, spiruline, pine (young sprouts), and a cinnamon infusion. 

The answer finally tnrned ont to be a rare coincidence of unusual weather and a cyclical peak in caterpillar reprodnction. The popnlation of tent caterpillars reached a 10-year high and they munched on wild cherry leaves to gorge their hunger. 

Wild cherry leaves contain snbstances that can form naturally occurring cyanide. All livestock owners know abont wild black cherry leaves that are safe for animals to eat when they are green and again when they are completely dry. But in the wilted stage, they can be deadly. 

Unusual weather in March and April increased the potency of young cherry leaves. However, mares rarely had the opportnnity to eat cherry leaves. Horse owners would have eliminated them from pastures long ago. 

This is where the hungry caterpillars came into the picture. They ate the cherry leaves and migrated to other sites, carrying the toxic chemicals with them. Mares ingested the abnormally abundant insect larvae or their feces from grass or water tanks, poisoning their babies in the womb.

Frequently overlooked as a nutrient, water can have a major influence on the growth of immature insects (Scriber and Slansky, 1981). Water content alterations in artificial diets (Reese and Beck, 1978) and in excised cherry leaves (Scriber, 1977) affect the metabolic costs, efficiencies and growth rates of Lepidoptera. In spite of a variety of behavioral, physiological and ecological adaptations to acquire adequate water and avoid desiccation, low leaf water content has remained a major evolutionary hurdle for most phytophagous insects (Southwood, 1972).

Other materials based on EDA have also been suggested as fungicides. The most important of the imida2oline type (162) is 2-heptadecyl-2-imida2oline (163), prepared from EDA and stearic acid [57-11-4]. It is used as the acetate salt for control of apple scab and cherry leaf spot. A 2 1 EDA—copper sulfate complex has been suggested for control of aquatic fungi (164).

Fungicides are used on stone fruit crops in the eastern United States to control brown rot blossom blight and fruit rot (Monilinia fructi-cola), cherry leaf spot (Coccomyces hiemalis), powdery mildews (Sphaerotheca pannosa and Podosphaera oxyacanthae), and scab (Clado-sporium carpophilium). In the northeastern states about six applications are applied per season while in the southeastern states up to ten applications are applied.

Folpet is a protective leaf fungicide. Its mode of action inhibits normal cell division of a broad spectrum of microorganisms. It is used to control cherry leaf spot, rose mildew, rose black spot, and apple scab. It is used on berries, flowers, ornamentals, fruits and vegetables, and for seed- and plant-bed treatment. Folpet also finds use in paints, plastics, and treatment of internal and external structural surfaces of buildings to control fungal attack.50,52...

The death of leaf cells can result in well-defined, circular spots. Spots can be of various colors and may change colors as symptoms progress. In some cases, as in cherry leaf spot, the dead cells eventually fall out, leaving holes. 

Folpet inhibits cell division in many microorganisms. As a fungicide, it is used to control cherry leaf spot, rose mildew, rose black spot, and apple scab and is also used on berries, flowers, fruits, and vegetables for seed treatment.

As evidenced by the dendrogram in Fig. 4.3, separation down to species level is superimposed by a high similarity within genera. Examples for a high chemical similarity within the same genus are the spectra obtained from two species of Prunus, Bird Cherry and Wild Cherry. They form a distinct group, as do also two Acer species, Norway Maple and Sycamore Maple (see Fig. 4.3). However, the pollen spectra from a third species of Acer, the Ash-leaf Maple (or Maple Ash), resemble those of oak and sycamore tree pollen rather than the other Acer species. The tree is native to North America, different from the other two Acer species, which are natives to Europe and Asia. 

New leaves twisted or curled and covered with a sticky coating. Cause Black cherry aphids. Look on leaf undersides for clusters of these tiny black insects. The sticky coating is honeydew secreted by these pests. Leaves also may be covered with a black fungus, called sooty mold, which feeds on honeydew. Aphids... 

Leaves unusually small leaves yellow or oddly shaped. Cause Viral infection. A few viral diseases cause leaf anomalies in peach trees. One particular virus, known as peach rosette, causes trees to produce shoots that have abnormally short distances between the leaf nodes. Avoid viruses by starting with clean stock. Avoid planting near possible virus carriers, such as old peach trees or wild choke-cherries Prunus virginiana). Remove and destroy infected trees.
