Sistemas de plantio direto e pacotes tecnologicos para as cultivares de algodao da coodetec e demais no mato grosso : aditivo 2 : Pragas e biodiversidade nos sistemas de cultivo algodoeiros do Mato Grosso, avaliaçao dos riscos fitossanitarios na safrinha e de uma proteçao alternativa. Safra 2004-2005

The general objective of the project is to identify crop systems which facilitate a better control (natural and/or chemical) of pests with lower protection costs. The project of the 2004-2005 harvest aims to answer the following specific questions : - What are the crop systems which facilitate a better pest management ? What are the species which can be considered as regular pests or biodiversity indicators and how to consider these species ? - What are the crop residues, mulch or cover crops, which can facilitate the natural biological control of the pests ? - What are the risks of multiplication of the pests (Anthonomus grandis, Spodoptera frugiperda, Pectinophora gossypiella) developing in the secondary crop season (called "safrinha") and how to manage the increasing species S. frugiperda ? The research will be carried out on the same experimental design of Fazenda Mourao in Campo Verde-MT, as part of the project submitted to FACUAL (" No-tillage systems and technological packages for cotton cultivars grown by Coodetec and others in the Mato Grosso "). After the two first campaign results with the experimental matricial design, we want to increase the qualitative and quantitative observations, particularly with a comparison of an alternative protection option crop system, the monitoring of the fauna in the mulch in the various crops of the systems, and the caracterization of the Spodoptera species complex.
