Sesame Seed (Benne, Benni, Bene Seed). Sesame seed is the whole dried seed of Sesamum indicum L. (PedaUaceae), an annual plant now cultivated in Mexico and Central America, although indigenous to Indonesia and tropical Africa. It may be the oldest condiment known. The seed is small, shiny, and oval shaped, about 0.32 cm long. The unhuUed seeds are dark and the hulled seeds are pearly white. Sesame seeds, when baked, have a pleasant, roasted, nutty flavor. They are used in baked goods and in confections, eg, halvah. [Pg.29]

For metals and crystals, cleavage can attempt similar feats, but the results are not as good. Metal surfaces formed by cleavage are usually not atomically flat. When an Au wire is flame-annealed in a hydrogen-air flame, the Au(lll) face is formed preferentially, since it has a lower surface energy than the Au(100) or Au(110) faces, but these Au(lll) faces resemble New Mexico mesas the atomically flat region may be only 50 x 50 nm, and is surrounded by one- or two-atom steps leading down to the plain, and then on to the next mesa. [Pg.45]

Corn seed treatment has not usually resulted in improvement in stand where it has been tried in Mexico. High soil temperatures, favoring rapid emergence, tend to reduce any possible benefit. One important need is a good repellent that can be safely applied to corn seed. Rodents and crows are common thieves in recently planted fields, and are responsible for much of the replanting that has become customary in tropical lands. [Pg.5]

The presence of aphids, Toxoptera graminum (Rondani) and Macrosiphum granarium (Kirby), on wheat during March and April has caused considerable alarm to wheat farmers in central Mexico. It has been found, however, that in the majority of cases the aphids do not represent a serious economic problem. Naturally occurring predators are able to reduce the aphid populations rapidly. For cases in which this natural biological control is not effective it has been found that benzene hexachloride (BHC) applied as a dust gives good control of these pests. [Pg.6]

In a very local area in Mexico, the larvae of Phyrdenus muriceus have been found to be an important pest of potatoes. The application of soil insecticides, including aldrin, dieldrin, and chlordan, have given good control in experimental tests. Further work, however, needs to be done with this pest before definite conclusions may be made. As in other countries, the use of DDT applied to the foliage results in healthier plants and greater yields. [Pg.7]

Rats are a serious pest in cane fields in several countries, particularly in Australia, Taiwan, British Guiana, Puerto Rico, and Mexico. They are a factor in dissemination of leaf scald disease in British Guiana. Trapping and warfarin [3-(alpha-acetonylbenzyl)-4-hydroxycoumarin] baiting are practiced. Warfarin is used by an estimated 80% of the cane growers in Puerto Rico. Mexico uses 1000 pounds of warfarin annually. British Guiana uses 12,000 pounds of 1% warfarin annually and anticipates this demand will continue indefinitely. Taiwan reports use of 6565 pounds of 0.5% warfarin on 13,000 acres with good results and expects to continue its use. [Pg.18]

A severe thrips infestation occurred in 1953 in cacao plantations in the Comal-calco area of the state of Tabasco, Mexico. The trees suffered a nearly total defoliation. Control was reported to have been obtained by applications of aqueous solutions of Deenate 75W (DDT 75%) according to the formula Deenate 150 gram, Spreader Sticker 15 cc., and water 100 liters. Bordeaux mixture and milk of lime have also been reported as giving good control in some localities. [Pg.24]

Natural gas has been discovered in many places in the world and many countries have petroleum. The chemical industry has a greater value added than is possible when gas or oil is used for energy. Newcomers are Saudi Arabia, Canada, Mexico, South American countries, former members of the USSR, and Asian countries. In Taiwan the chemical industry is 30% of manufacturing compared to 11% in the U.S. Saudi Arabia has 25% of the world s oil reserves and a good supply of gas. These countries at least enter the chemical business to provide for their own needs. [Pg.14]

Dr. Chambers has written an excellent review article on "Attractants for Fruit Fly Survey and Control" (5 ). In this review. Chambers discusses the development of parapheromones and food baits and the implementation of these attractants. Thousands of compounds were screened in Hawaii and in Mexico during the period of 1950 to 1955 (6), and this screening process yielded some promising candidates. Methyl eugenol, proposed by Steiner in 1952 (X), remains the most effective lure for the Oriental fruit fly. Cue lure, found by Beroza in 1960 (8), is a good lure for the melon... [Pg.433]
