To preserve the planet's productivity it is vital that less potent insecticides be developed and utilized worldwide. This paper reviews one possible alternative to chemical insecticides by examining the evidence for the potential of diatomaceous earth, a nontoxic naturally occurring material, as a pest control agent. Tests conducted by the United States Department of Agriculture have shown that diatomaceous earth can be more effective than malathion in controlling a variety of insects, including the lesser grain borer, rice weevil, and confused flour beetle. It is possible that with proper climatic conditions and application techniques diatomaceous earth could be effectively used on field crops as well, thus reducing the amount of chemical residues in water, soil, and atmosphere. Diatomaceous earth is not a miracle cure to the insect problem, but it does have many attractive features that should be considered by the world's agriculturalists.</p></div>","PeriodicalId":100064,"journal":{"name":"Agriculture and Environment","volume":"6 1","pages":"Pages 43-51"},"PeriodicalIF":0.0,"publicationDate":"1981-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0304-1131(81)90026-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76598480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Symptoms of the deteriorating physical environment include channel incision, gullying, stream capture, spawning of erosion cells and extensive mass movements, products of the increase of erosive energy throughput in the system. Separate experimental runoff plots were established in the basin to represent three different environmental conditions: re-vegetated hill slopes, cane fields and abandoned down-hill furrows. Analysis of data reveals an association between land use types and runoff. It supports the hypothesis that large-scale deforestation and cane growing since colonization have changed the hydrologic regime, bringing accelerated erosion to these areas outcropped by the relatively weak, impervious Joe's River Muds. The present “conservation” practice of down-hill furrows is aggravating the erosion problem further.</p></div>","PeriodicalId":100064,"journal":{"name":"Agriculture and Environment","volume":"5 4","pages":"Pages 285-308"},"PeriodicalIF":0.0,"publicationDate":"1981-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0304-1131(81)90045-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86648750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
