The alkaloid Nigellicine proved to be the pyridazino[l,2-u]indazolium-l 1-carboxylate (234) and forms yellow crystals (Scheme 77). It was isolated from the widely distributed herbaceous plant Nigella saliva L., which is used as a spice and for the treatment of various diseases (85TL2759). The structure was determined by an X-ray crystal structure analysis. The carboxylate bond distances are essentially equal (123.3 and 125.6 pm). An intramolecular hydrogen bond was found between the carboxylate oxygen atom and the hydroxy group. In mass spectrometry, the molecular peak was found at mjz —246 (20) and the base peak at mjz —202 which corresponds... 

The family Aristolochiaceae is a family of herbaceous plants often used in Asia and the Pacific to counteract snake poisoning, promote urination and menses, mitigate stomachache, and treat dropsy and skin diseases. During the past 20 years, members of this family, especially from the genus Aristolochia have attracted much interest and has been the subject of numerous chemical and pharmacological studies. The anti-inflammatory property of Aristolochia species is probably the result of a direct... 

Only live, clean plants free of insects, disease, molds, bryophytes, etc. are included. The collection of sample parts depends on plant habit, characteristics, and abundance. Woody species may be divided into several samples of leaves, twigs, bark, wood, roots, and fruits. Herbaceous plants, when abundant, are divided into aerial and below-ground parts otherwise they are collected as whole-plant samples. Samples are weighed fresh, before freezing. 

Unlike vegetable crops, which share many of the same pests, fruit crops are affected by a wide variety of insects and diseases. Because fruit crops are borne on so many types of plants—including fruit trees, berry bushes, vines, and herbaceous plants such as strawberries—they have a wide range of cultural requirements as well. However, regardless of the crop you are growing, there are basic steps you can take to help prevent and control insects and diseases. 

Plants Affected A wide range of woody and herbaceous plants. This disease is a serious problem on grapes. 

Throughout human history, natural products, compounds that are derived from natural sources such as plants, animals, or microorganisms, have played a very important role in health care and prevention of diseases. For example, some of the first records on the use of natural products in medicine were written in cuneiform in Mesopotamia on clay tablets and date to approximately 2600 BC Chinese herb guides document the use of herbaceous plants as far back in time as 2000 BC Egyptians have been found to have documented the uses of various herbs in 1500 BC. 

Additional reasons to manage weeds in ornamental plants and conifer trees include fire protection, frost protection, rodent and disease mitigation, nutrient management, and aesthetics. Uncontrolled weeds and brush become serious fire hazards in the fall or early spring when herbaceous weeds are dry. Plantations of conifers have been lost because weeds were not controlled and fires started. Fires are less destructive when herbaceous vegetation is controlled. 

Portulaca oleracea commonly known as purslane belongs to the family Portulacaceae and is an herbaceous cosmopolitan weed. P. oleracea is one of the major sources of omega-3 fatty acids and was found to produce beneficial effects on cholesterol and triglyceride levels in heart disease and in strengthening the immune system. The plant also possesses marked antioxidant activity (Reid, 1986 Chevallier, 1996 Hocking, 1997). 

The symptoms listed below represent damage caused by pests and diseases that attack a wide variety of herbaceous perennials. Controls for these problems do not vary significantly among plant species. 

TM) Turf and Ornamental Fungicide is a finely ground wettable powder containing 50% by weight of thiophanate for prevention and control of Dollar Spot, Copper Spot, Brown Patch, Red Thread, Fusarium roseum, Helminthosporium. Stripe Smut and many other diseases. It is labelled for use also on shade trees, ornamentals, herbaceous annual, perennial and bedding plants, and flower beds.
