Book Description :

More and more biologists, chemists, pharmacologists, toxicologists, governmental agencies, and "food control" (regulatory) officials around the world are finding it increasingly difficult to keep abreast of the technical literature in the pesticide field; indeed, many libraries do not have even a small proportion of the journals and other sources that now regularly contain research, development, and application information about all aspects of modern chemical pest control. As a result, a very large number of requests has come to RESIDUE RE VIEWS to publish detailed digests of information on single pesticide chemicals so that the interested person in any part of the world could easily be brought up to date with all available important information without having to search probably several hundred literature sources, many of them obscure or simply not available except in very large libraries. The service and convenience rendered the readership by such a series of volumes on major individual pesticide chemicals would therefore be considerable. Type and scope of coverage in this series of single-pesticide vol umes will of course vary with available information. The coverage 'lhould be as complete as possible, however, to be of maximum value to all interested individuals, industries, research institutions, and governmental agencies concerned with the continuing production of an adequately large yet safe food supply for the world. Among the topics bracketed for a single pesticide should ideally be: I. Introduction II. History of development and use, including alternate names around the world, patent information III.

Book Description :

Growth chamber bioassay experiments using oats (Avena sativa L. var. Russell) were conducted over a 2 year period using soil from 4 locations. The degree of herbicide movement in the soil profile, the influence of cropping systems on dissipation and the degradation rate of atrazine, SD15418 and S6115 were investigated. In all cases, the greatest amount of herbicide was retained in the upper 5 cm of soil. As the rate of herbicide application was increased, more herbicide was detected in the lower soil horizons. There appeared to be a greater downward movement of herbicide in the plots containing corn than in fallowed plots. More herbicide residue was detected at the Winnipeg and Portage la Prairie (Portage) sites (heavy clay soils) than at the Graysville and Carman sites (very fine sandy loam soils). At the Graysville and Carman sites, triazine herbicides appeared to breakdown more rapidly in fallow than in the corn plots. No difference was detected at Winnipeg or Portage between corn and fallow plots. It appeared that there was a greater percent breakdown of triazine herbicides at high rates than at low rates. Field bioassay experiments showed that there was more severe injury to oats due to triazine residue at the Winnipeg and Portage sites than at the Graysville site. At all sites atrazine and S6115 caused a greater degree of oat injury than SD15418. At the Winnipeg and Portage sites there appeared to be similar triazine injury to oats grown on either corn or fallow plots. At the Graysville site there was less injury to oats grown on the fallow plots than on the corn plots.

Book Description :

The triazines are one of the most widely used herbicide classes ever developed, and play a role in managing herbicide-resistant weed populations in sustainable agricultural production systems. The triazines are traditionally valued for their persistence and season-long weed control in over 50 crops including corn, soybeans, wheat, and vegetables. The literature suggests that atrazine, the most widely used triazine, may no longer remain persistent in soils due to enhanced microbial degradation. Experiments examined the rate of degradation of atrazine and two other triazine herbicides: simazine and metribuzin in both atrazine adapted and non-adapted soils from across the United States. Additional studies examined the rate of atrazine dissipation in flooded and non-flooded soils, as well as soils with varying history of atrazine use. In soils with a history of atrazine use, the t1/2 [half-life] of atrazine was up to 40 times more rapid than in soils with no history of atrazine use. Simazine t1/2 was at least 2.4-15 times more rapid in history soils than non-history soils, and metribuzin was degraded at 0.6, 0.9, and 1.9 times the rate in the same soils. These results indicate cross-enhancement of the symmetrical triazine simazine, but not for metribuzin, an asymmetrical triazine. In soils with 3, 5, and 10 years of previous atrazine use, atrazine t1/2 was 2.66, 4.44, and 2.14 respectively, indicating that atrazine adapted soils may develop rapidly. Finally, atrazine dissipation in flooded and non-flooded soils appears rapid, indicating that soybeans are a viable option when replanting production con fields previously treated with atrazine.

Book Description :

Studies were initiated to determine the response of two common groundsel biotypes (Senecio vulgaris L.) to several s-triazine herbicides. Herbicides tested were: 2-chloro-4,6-bis(ethylamino)-striazine (simazine), 2-chloro-4-(ethylamino)-6-(isopropylamino)- s-triazine (atrazine) 2-(sec-butylamino)-4-(ethylamino)-6-methoxys- triazine (GS-14254), 2, 4-bis(isopropylamino)-6-methoxy-striazine (prometone), 2-(tert-butylamino)-4-(ethylamino)-6-methylthio- s-triazine (terbutryn), and 2, 4-bis(isopropylamino)-6- methylthio-s-triazine (prometryne). One biotype was much more susceptible than the other. Sensitive plants were effectively controlled by 0. 5 ppm of atrazine and simazine, 1 ppm of GS-14254 and prometone, and 4 ppm of prometryne. The resistant biotype failed to show any symptoms of photosynthesis inhibition at the highest rates tested, i. e. 4 ppm of simazine and 30 ppm for atrazine, GS- 14254, prometone, and prometryne. Both biotypes were resistant to terbutryn at 30 ppm. When a triazine herbicide was applied, the susceptible plants became chlorotic and died; resistant plants never exhibited these symptoms. Photosynthesis was completely inhibited by simazine in susceptible (S) plants but resistant (R) plants were unaffected. Photosynthesis in the susceptible biotype resumed when the herbicide was removed after 24 hours. Absorption and metabolism of simazine were explored as possible explanations for the herbicide tolerance exhibited by the R biotype. Both biotypes absorbed the herbicide equally well, and no differences in simazine metabolism were found which could explain the mechanism of resistance. Plants of both biotypes were subjected to 14C-simazine for up to 96 hours. The greatest concentration of 14C activity (80 to 90%) was located in the chloroform-soluble fraction of the foliage tissue of each biotype. The 14C in this fraction of the plant extracts was determined by thin-layer chromatography to be similar to 14C- simazine. Small amounts of 14C activity (10-1 5%) were isolated in the water-soluble fraction of the plant extracts, but time-course studies revealed no differential increase in watersoluble simazine metabolites by either biotype. A similar metabolism study using corn was conducted, which substantiated the findings of numerous workers. Several alternative explanations for the difference in triazine sensitivity between the two common groundsel biotypes are suggested.

Book Description :

This chapter is a review of literature concerning the fate of chloro-s-triazine herbicides, particularly atrazine, in the environment. It addresses the distribution of such herbicides and their metabolites in the soil and in water bodies, including the conditions that affect their transport mechanisms. The biodegradation pathways regarding the microbial degradation are presented as well as modification mechanisms of the compounds in plants capable of tolerating their action. Studies on the influence of the compounds on animal and human physiological processes and health, that is distribution of atrazine in the animal organisms, effects on the regulatory platform in the liver, possible carcinogenesis and endocrine disruption risks are assessed. Toxicity tests used for evaluation of the toxicity of the compounds are critically reviewed. Possible methods for atrazine degradation, including advanced oxidation procedures (AOP techniques), are outlined.

Book Description :

Triazine herbicides are used in aquatic management primarily to control macrophytes and undesirable phytoplankton populations. Triazines used for terrestrial weed control also enter aquatic systems through runoff, aerial drift or from spillage. This study assesses the impact of two of these triazines, simazine and terbutryn, on the structure, function and biomass of periphytic algae within in-situ littoral enclosures. Secondary effects of treatment on water chemistry were also monitored during an 87 days experimental period. The second half of this study describes an automated quantitative grain density microautoradiography procedure. The effects of Lugol's iodine on isotope leakage from cells preserved for autoradiography, was demonstrated using three haptobenthic diatom species. The applicability of using this technique to evaluate intra and interspecific variation in algal response to triazine exposure in-situ was also discussed.
