Common Plants Can KENNETT SQUARE (Chester Co.) The-leaves, flowers and berries of some common plants may be beautiful, but they can be deadly if eaten by livestock and pets, according to doctors at the University of Pennsylvania School of Veterinary Medicine. Rhododendron, azalea, night shade, acoms, mountain laurel cherry trees, apple trees and yew are all toxic. “Even maple leaves, which are not usually harmful, become acutely toxic in the fall,” said Dr. Robert Poppenga, director of the toxicology laboratciy ai ihe New Bolton ',’rr.ipr, Penn's iarge-ani mal facil'ty in Kennett Square. “Plant poisoning in pet animals is less common than in livestock,” said Dr. Michaela Kristula of New Bolton Center’s Field Service. “Small pets can be poisoned by household plants such as dieffen bachia, philodendron, and similar common house plants.” Leaves of the red maple, Acer rubrum, which become increas Field Day Set For Tree Fruit Growers BIGLERVILLE (Adams Co.) —Tree fruit growers in Pen nsylvania and neighbor ing states are invited to a Held day July 26 from 8:30 a.m. to 3:30 p.m. here at Penn State’s Fruit Research and Extension Center. Visitors will tour orchard research plots and hear presentations highlighting new research and extension programs. The entomology program will include the latest information on various integrated pest management tac tics, including degree days and weather fore casting, mating disrup tion, new biological control agents, ground cover management, and insect growth regula tors. Participants will also learn how to com bat insecticide resis tance and what is being done to understand the development of resis tance in insects. The horticulural information that will be highlighted will include production data and economic evaluation of apple rootstocks, apple root system dynamics, performance of scab resistant apple varieties, peach and apple thin ning programs, and apple plant growth reg ulators to manage excessive tree vigor. The postharvest por tion of the program will include the introduction of the new postharvest physiologist and research program. Work conducted over the past three seasons concerning controlled atmosphere (CA) stor age of apples from reduced pesticide trials will be briefly discussed. Presentations will ingly toxic as they dry out, are particularly dangerous in the fall. If eaten by horses, the toxin con tained in the leaves causes hemo lytic anemia and secondary kidney damage, usually resulting in death or permanent kidney dysfunction. Other maple species are not con sidered toxic. “There is no known antidote for maple-leaf poisoning,” said Kris tula. “Some horses die from the poison only 12 hours after it is in gested, so it is important to have the horse examined by a veterinar ian immediately if you suspect he may have maple leaf poisoning.” Clinical signs associated with he molytic anemia resulting from toxins include lethargy, increased breathing rate, jaundice, and red dish-brown colored urine in the early stages. To protect the animals, Kristula suggests horse owners take the following precautions: • Do not plant red maple trees in or near your horse’s pasture, as horses may nibble the leaves over include the control ot major diseases of tree fruit crops caused by .fungi, bacteria, viruses, and nematodes. Empha sis will be placed on methods helpful in reducing pesticide usage, including anta gonistic bacteria and cover crops useful in controlling nematodes.

This is especially important in the fall when pastures dry out and grass is sparse. Other plants to watch out for are several species of nightshades and horsenettle. The berries and vege tation are poisonous. Toxicity is not lost in drying, thus contamin ated hay may be toxic. When in gested, they cause neurologic and digestive problems. These plants are found in disturbed soil, woods, meadows and pastures and culti vated fields. Nightshade poison ing affects all animals, but horses, sheep and goats are the most likely to nibble on it if feed is not avail able. In sheep, severe intestinal les ions develop as a result of horse nettle toxicosis. There may be in flammation of the mouth and eso phagus in calves. Nervous symptoms may include apathy.

The dried berries of horsenettle, which cling to the plant over the winter, are so potent they can kill cattle in March. Buttercups that proliferate in fields in May and June can cause critical gastrointestinal problems in livestock. In severe cases but tercups induce convulsions ending in death. Dried material in hay re portedly is not poisonous. Most livestock will not eat the plant when plenty of other forage is available. Acom poisoning can cause di gestive problems, jaundice, per manent kidney damage and even tually, death. Calves, goats, and sheep are particularly susceptible to this poison; horses are rarely af fected.

The leaves and buds of hydrangea con tain poisonous constituents that cause painful sickness in livestock and humans. Iris, if eaten in large quantities, causes gastroenteritis and labored breathing in livestock. The common morning glory’s leaves and stems are toxic. Espe cially predisposed to poisoning from this creeping vine are hogs, sheep, cattle and goats. Prolonged consumption results in anorexia, coma, and, in severe cases, death. Yew leaves are extremely toxic for all animals. Cattle seem parti cularly sensitive to the toxin. As little as one mouthful of the plant can be fatal, so it is essential for owners to dispose of clippings out of the animals’ reach whenever pruning yew trees and shrubs. A particularly harmful plant for horses is the black walnut Inges tion is not necessary for poisoning to occur. Black walnut trees in the (Turn to Pago D 3)
