摘要

在罐式混合药剂中加入助剂可以提高作物的农药施用效果。本研究评估了佐剂在不同剂量下对水溶液物理化学特性的影响。在推荐剂量(全剂量)和推荐剂量的一半(半剂量)下,除单独蒸馏水外,对8种市售佐剂水溶液的氢离子电位、电导率、密度、动态粘度、表面张力和稳定性进行了评价。采用分层析因方案(8 ×2+1),采用4个重复的随机设计。结果表明,佐剂对水溶液理化性质的影响取决于其化学性质和配方。即使对于相同推荐使用的添加剂,这些特性的性能也不相似。各佐剂的理化特性受剂量变化的影响不同。pH、表面张力和粘度对佐剂的添加最为敏感。

Características físico-químicas de soluções aquosas com adjuvantes de uso agrícola
SummARY Pesticide application efficacy on crops can be improved by adding adjuvants to tank mixtures. The present study evaluated the adjuvant effect, in different doses, on the physico-chemical characteristics of aqueous solutions. The hidrogenionic poten tial, electrical conductivity, density, dynamic viscosity, surface tension and stability of aqueous solution with eight commercial adjuvants were evaluated at the recommended dose (full-dose) and at half of it (half-dose), besides the distilled water alone. A randomized design with four replications was used, in a hier archy factorial scheme (8 ×2+1). From the results it can be con cluded that the adjuvant effect on the physico-chemical charac teristics of aqueous solutions was based on their chemical properties and formulation. The performance of these characteristics was not similar, even for additives with the same use recommendation. The physico-chemical characteristics for each adjuvant were affected differently by the dose alteration. The pH, surface tension and viscosity were the most sensitive characteristics to the adjuvant addition.

期刊介绍: Interciencia is the monthly multidisciplinary publication of the INTERCIENCIA Association. It is dedicated to stimulate scientific research, its humanitarian use and the study of its social context, specially in Latin America and the Caribbean and to promote communication between the scientific and technological communities of the Americas. Interciencia has been published uninterruptedly since 1976. Its Founding Director, Marcel Roche (endocrinologist and sociologist of science) was editor until 2008, and thereafter Miguel Laufer (neurobiologist) has been in charge. It has been included since 1978 in the Science Citation Index and other international indexes, and since 2008 it maintains an open access electronic version with material from 2005 onwards. The priority areas of the journal, without exclusion of other areas, are Agronomy, Arid Lands, Food and Nutrition, Biotechnology, Ecology and Environment, Energy, Innovation and Technology Transfer, Marine Resources, Non-renewable Resources, Science Education, Science Policy, Study and Sociology of Science, and Tropical Forests. Interciencia publishes in Spanish, Portuguese and English research and review articles, communications and essays, all of which are subjected to peer review. Additionally, it includes non-refereed sections such as Editorial, Letters to the Editor, Open Town Hall, Book Reviews and Upcoming Events. All the material submitted to the journal for publication and accepted by the Editorial Committee in view of its quality and pertinence is subjected to review by peer specialists in the corresponding fields of knowledge. Neither the INTERCIENCIA Association, nor the journal or the institutions to which the authors belong carry responsibility for the contents. Signing authors are responsible for the material published under their names.
