Flower drop

Shortage of water makes plants wilt, which even for short periods weakens them, leaving them more vulnerable to attack. Prolonged water shortage can result in stunted growth and tissue death in all or parts of the leaves. Water shortages can have delayed effects on plants flower drop in camellias in spring is caused by dry conditions the previous fall. [Pg.86]

Symptoms A powdery white coating on buds, leaves, and stems. Flowers drop leaves distort, wither, and fall. Early infections cause weblike russeting on fruit... [Pg.321]

Eggplants are susceptible to many of the same problems, pests, and diseases as tomatoes, including flower drop or misshapen fruit due to extreme temperatures, flea beetles, Colorado potato beetles, aphids, hornworms, mites, Verticillium and Eusarium wilts, tobacco mosaic virus, and anthracnose fruit rot. See the Tomato entry beginning on page 227 for symptoms, causes, and controls. [Pg.93]

Besides some occasional gas or upset stomach, this plant is not very toxic to people. It is however a fast acting herbicide, very toxic to other plants. In nature the leaves and flowers drop from the plant and decay into the ground. This deposits the poisons from the plant into the soil to deter competition from other plants. [Pg.48]

In the past, treatment of diseases caused by nematodes was primarily concerned with those parasites that infected humans. Plants or plant juices were traditionally used as vermifuges. The juice of marigold flowers dropped into the ear was reputed to kill worms [28]. Some marine algal... [Pg.430]

Ornamentals are treated with GA for a variety of purposes including more profuse flowering, increasing flower number, and in some circumstances flower size. It is a common practice in the southeastern United States to gib camelHas prior to flowering, ie, a small amount of the potassium salt of GA at 100 ppm is dropped into the floral bud at a very early stage of development to produce large showy flowers. [Pg.420]

Naphthalene acetic acid is used to thin apple and pear blossoms and to control apple and pear preharvest drop (10). It also is used to induce flowering in pineapple, but conversely inhibits sprouting in potatoes, sweet potatoes, and turnips (Brassica rapd) (23). It also is used to promote rooting in... [Pg.425]

Tinctures are very concentrated. For most elder flower tinctures, an appropriate dose would be 20 to 40 drops in a bit of water. This can be taken 3 times daily for a chronic condition. However, if it is an acute condition, once every 1 or 2 hours that you are awake would be more appropriate. To determine dosage for a child, to treat a fever, for example, take the weight of the child and divide by 150. Thus a 50-pound child would get 1/3 of the adult dose. The tincture can be put in a bit of water or juice to dilute the taste of the alcohol. [Pg.32]

Don t freak out when the plants go deciduous, usually about a year or a year and a half from sprouting. They drop almost all their leaves except the ones at the tip of the stems, turn yellow and mottled, and you think they re dying. They re not - in fact, they re growing Within a few days, little spike-shaped green sprouts will appear, and tiny, usually white, flowers. After a few years, the flowers will start producing little... [Pg.176]

Digging In green manure Green manure plants need to decompose quickly once incorporated into the soil. Younger plants will rot down more rapidly, so dig them in before growth begins to toughen up, ideally before flower buds appear. If you leave the plants to flower, seed may form and ripen, and drop into the soil to reseed, which may or may not be useful. [Pg.51]

What to do Hand-pick larvae several times weekly and drop them into soapy water. Till crop residues into the soil before adults emerge in spring. Attract native parasitic wasps by planting pollen- and nectar-rich flowers. [Pg.324]

What to do In early morning, shake beetles from plants onto dropcioths, then drop into soapy water to kill them. Cover crop plants with row cover or mesh. Plant pollen- and nectar-rich flowers to attract native species of parasitic wasps and flies. [Pg.331]

Hawthorn has long been used as a medicinal substance, and an extract such as WS 1442, a formulation of hawthorn leaves with flowers, has been evaluated in different studies for treatment of heart failure (40 2). Patients with New York Heart Association class II heart failure participated in a placebo-controlled, randomized, multicenter trial. They received 30 drops of the extract three times daily for eight weeks. At the end of the study, heart failure condition was improved (41). A meta-analysis of available clinical trials suggests that the extract is useful as an adjunct treatment for patients with mild to moderate heart failure (42). Therefore, it is likely that hawthorn products would be administered together with digoxin in clinical management of patients (Fig. 4). [Pg.136]
