Bears weed

ProfiGene) had been grown the previous season but failed to provide adequate weed control to eliminate drug-bearing corn volunteers. Eventually, the corn-contaminated soybean was harvested and pooled with other soybeans. The entire batch had to be destroyed. [Pg.191]

Petroleum products such as stove oil were used as selective herbicides in fields of guayule—a rubber-bearing shrub—grown experimentally in California and the Southwest during World War II. Mineral spirits are used rather extensively for weed control in cranberry bogs in the lake states and in the Northwest. [Pg.84]

Benzofurans 247 <2002USP6352958> and 248, both of which bear pyrimidinedione groups, are pre- and postemergent herbicides. The second is reported to have application to broad-leaved weeds, cyperaceous weeds, and the protection of rice crops <2000USP6130187>. [Pg.601]

Phytotoxic compounds are produced by many crop species, and some of these compounds may play a role as allelochemicals in plant interference. This has bear hard to prove, much less taken advantage of in weed management. Many crops have been screened for allelopathic potential [28]. However, in all but a few cases, the effects of crop allelopathy are quite subtle compared to the effects of chemical herbicides. Efforts to produce allelopathic crop varieties through conventional breeding have not generated commercial varieties sold with this trait. Molecular biology approaches to this problem might be helpful. [Pg.150]

The naming of a new product is not as simple as it may appear at first glance. The name must be unique in the field in which it is to be used. Because of the many thousands of names now registered, it is not too easy to find a name that is suitable for the product and yet does not bear too close a resemblance to a trademark already in use. Generally, a preliminary list of names is drawn up and is then weeded out until only a very few names are left. Even these names, however, may have to be discarded because conscious or subconscious analogies are drawn from existing names. [Pg.172]

Jimson weed is a malodorous, fruit-bearing plant with dark green pointed leaves and tubular white flowers. It grows 3-5 ft in height. Jimson weed is native to Asia however, it is also found throughout the United States and elsewhere. Other names for this plant and related species with the same active substance are locoseed, locoweed, devil s trumpet, Tolguacha, apple of Peru, Jamestown weed, devil s apple, thorn apple, stinkweed, hyoscyamine (leaves, roots, seeds) hyoscine (roots). [Pg.2029]

Auxins are one of the five major classes of plant-produced hormones that affect plant growth including bud formation and root initiation (see http //en.wikipedia. org/wiki/Plant hormone Auxins), lndole-3-acetic acid is the most common auxin found in plants. Although the small amounts produced internally have the desired effects, auxins are toxic to plants in larger amounts. The nefarious weed-control products 2,4-D and 2,4,5-T target the auxin receptor but bear little resemblance to the natural ligand. Other man-made auxins such as 1-naphthaleneacetic acid and indole-3-butyric acid are used, not to kill weeds, but to stimulate root production in cuttings taken from the parent plant (Scheme 6). [Pg.35]

Kaundun and Windass [56] described an alternative derived Cleaved Amplified Sequence (dCAPS) method [57] that can be used on several grass weeds and that offers the additional advantage of easy discrimination between homozygous and heterozygous LI781 mutation bearing plants. [Pg.343]

Facilities for storage of research materials in the laboratory should be selected with as much care as any other item of equipment. Many chemicals may be stored on ordinary shelves or cabinets, with only common sense safety provisions being necessary. Obviously, the shelves or cabinets must be sturdy enough to bear the weight of the chemicals. Storage should be such as to make it unlikely that the materials wUl be knocked off during the normal course of activities in the room. Shelves should not be overcrowded. It should not be necessary to strain to reach materials or to return them to their places. Incompatible chemicals should be stored well apart. Finally, the amount of storage should not be excessive, in order to restrict the amount of chemicals not in current use that would otherwise tend to accumulate within the facility. Periodically, one should weed the shelves of chemicals which have not been used for some time and for which no immediate use is foreseen. Older chemicals are rarely felt to be... [Pg.142]
