| The protective, eradicative and curative activities of the fungicides azoxystrobin, tebuconazole, pyraclostrobin+metiram, and ciproconazole against grapevine rust, were determined in greenhouse. To evaluate the protective activity, leaves of potted ´Niagara´ (Vitis labrusca) vines were artificially inoculated with an urediniospore suspension of Phakopsora euvitis four, eight or forteen days after fungicidal spray; and to evaluate the curative and eradicative activities, leaves were sprayed with fungicides two, four or eight days after inoculation. Disease severity was assessed 14 days after each inoculation. All tested fungicides present excellent preventive activity against grapevine rust; however, tebuconazole and ciproconazole provide better curative... |

| Em Rondônia, capim-amargoso (Digitaria insularis (L.) Mez ex Ekman), capim-colchão (Digitaria horizontalis Willd.), capim-milhã (Digitaria ciliaris (Retz.) Koel), capim pé-de-galinha (Eleusine indica, (L.) Gaertn) e capim rabo-de-burro (Andropogon bicornis L.), são ervas daninhas muito freqüentes em cultivos de seringueira, o que justifica a realização de trabalhos específicos para seu controle. O objetivo deste trabalho foi avaliar e comparar nas condições de campo, a eficácia de três herbicidas pós-emergentes no controle de gramíneas importantes em cultivo de seringueira em Rondônia. |

| The objective of this study was to find effective fungicides against eucalypt powdery mildew. Fungicides tested were chlorothalonil, fenarimol, sulfur, tebuconazole, propiconazole, benzothiazole, pyraclostrobin + epoxiconazole and triadimenol. These fungicides were sprayed on Eucalyptus benthamii seedlings in a greenhouse infested with powdery mildew. Severity was evaluated at 9, 16, 23, 30 and 37 days after spraying, classifying symptoms observed with a scale 0 (symptoms absent) to 4 (strong symptoms). Best treatments were obtained with pyraclostrobin + epoxiconazole, propiconazole + trifloxystrobin and triadimenol, with an infection index average of 0.39, 0.63 and 1.01, respectively. |

| The objective of this research was to determine, in field conditions, the minimal of phosphine effective dose for the cashew root borer control. Three experiments were set up at three different periods: August, October and November, 1994, to control the cashew root borer, Marshallius bondari Rosado-Neto (Coleoptera: Curculionidae), in Piaui State, Brazil. One, two, three and six phosphine tablets of three gram each, per plant were tested. In the August essay, phosphine was inefficient to control the borer. In the October essay, control was achieved using as little as 2 tablets per plant and in November with one tablet per plant to control the adult borers in the soil. Higher efficiency was achieved when treatment was applied far away from the last rain, in... |

| The usage of insecticidal plants and others insect resistant varieties can be strong allies to the Integrated Pest Management (IPM), being able to reduce the number of insecticides applications and to minimize its effect to the man and the environment.The following control techniques were compared in field conditions, investigating the late pest control of two determinate tomato cultivars: a) Conventional - sprayings of metamidophos, buprofezin, acephate, cipermetrin, abamectin, permetrin, teflubenzuron and lufenuron, applied every three to six days; b) IPM - action threshold of each pest to the spraying of imidacloprid, triflumuron, lufenuron and abamectin; c) IPM - Azadirachta indica (neem) - Action threshold of each pest to the spraying of the nim oil... |
