As new applications of silafluofen to termite control, we have developed another type of products in the forms of practical anti-termitic plastic sheets and anti-termitic plastic heat insulators which are free from the exposure risk of termite control operators and inhabitants to the sprayed chemical. Anti-termitic plastic sheets containing silafluofen in ethylene vinylacetate copolymer film have already been put into practical use, showing a high anti-termitic effect. Plastic heat insulators made of such materials as polystylene and polyurethane have the problem of the decrease in their insulating effect due to termite damage, although they have been widely used as building materials. To solve this problem, we prepared anti-termitic plastic heat insulators by impregnating silafluofen at concentrations of 0.1 ～0.3 % into plastic foam.

Received: 3 October 2011; in revised form: 29 October 2011 / Accepted: 30 November 2011 / Published: 8 December 2011 Abstract: With the advancement from natural pyrethrins to synthetic pyrethroids, their applications have expanded from household insecticides for indoor use against sanitary pests to outdoor use for agriculture, forestry, animal health, termite control, and many other pest situations. However, high fish toxicity and development of pyrethroid resistance in some pests have been cited as common shortcomings of pyrethroids. To overcome these pyrethroid problems such as high fish toxicity, Katsuda and fellow scientists invented silafluofen by introducing a silicone atom into the pyrethroidal chemical structure in 1984. In addition to the high insecticidal activity and low mammalian toxicity, this compound features low fish toxicity, chemical stability under sunlight, in the soil and under alkaline environments. These features make silafluofen unique among pyrethroids. In Japan, silafluofen has been used as an agricultural insecticide for 15 years since 1995 for various plants, especially useful for paddy rice protection because of its low fish toxicity.

  • Prohibited and Restricted Pesticides List Fair Trade USA® Agricultural Production Standard Version 1.1.0
    Version 1.1.0 Prohibited and Restricted Pesticides List Fair Trade USA® Agricultural Production Standard Version 1.1.0 Introduction Through the implementation of our standards, Fair Trade USA aims to promote sustainable livelihoods and safe working conditions, protection of the environment, and strong, transparent supply chains.. Our standards work to limit negative impacts on communities and the environment. All pesticides can be potentially hazardous to human health and the environment, both on the farm and in the community. They can negatively affect the long-term sustainability of agricultural livelihoods. The Fair Trade USA Agricultural Production Standard (APS) seeks to minimize these risks from pesticides by restricting the use of highly hazardous pesticides and enhancing the implementation of risk mitigation practices for lower risk pesticides. This approach allows greater flexibility for producers, while balancing controls on impacts to human and environmental health. This document lists the pesticides that are prohibited or restricted in the production of Fair Trade CertifiedTM products, as required in Objective 4.4.2 of the APS. It also includes additional rules for the use of restricted pesticides. Purpose The purpose of this document is to outline the rules which prohibit or restrict the use of hazardous pesticides in the production of Fair Trade Certified agricultural products. Scope • The Prohibited and Restricted Pesticides List (PRPL) applies to all crops certified against the Fair Trade USA Agricultural Production Standard (APS). • Restrictions outlined in this list apply to active ingredients in any pesticide used by parties included in the scope of the Certificate while handling Fair Trade Certified products.
