Poiretia latifolia Vogel has bioactive potential that includes antibiotic properties for human uses. The aim of this research was to develop an efficient method for vegetative propagation of P. latifolia by using cuttings as an aid to the selection and multiplication of interesting genotypes. In the first experiment, the cuttings were collected in vegetative and reproductive stages and treated with six plant growth regulators and distilled water. In the second experiment, the treatments consisted of cuttings from the apical, median, and basal branch segments. The treatment with the immersion of cuttings in 4,000 mg L-1 of IBA provided greater number and length of the roots, while high dilution of Calcarea phosphorica at 20CH produced longer branches. The cuttings of the middle and basal part of the branch were found to be more viable. It was achieved 79.17% of cuttings rooting using Calcarea phosphorica 20CH. The vegetative propagation employed in this work is a feasible option for the domestication, preservation, and cultivation of Poiretia latifolia.

Agroecological interventions for pest and disease management include several strategies to enhance homeostasis of the crop. Biological agents and homeopathic remedies are innovative and efficient agriculture technologies in the production of pesticide-free food. The objective of this work was to evaluate the effects of the biological control Trichoderma spp. and high-dynamized dilutions of Silicea terra to manage grey mould (Botrytis cinerea) and to promote growth in strawberry plants cv. San Andreas. The experiment was carried out in a greenhouse at EPAGRI experimental station, Lages-SC, 2017. The experimental design consisted of six treatments and five repetitions which were completely randomised. Each plot consisted of a strawberry plant cultivated in a 3.6 L plastic pot. Leaf area, number of leaves, root and leaf weights were assessed. The incidence and severity of grey mould on fruits was also evaluated. The statistical analysis was done by environment R®. Plants treated with Trichoderma spp. (WP formulation) resulted in a lower fruit incidence of B. cinerea fruits in all evaluated periods. Plants treated with Silicea12CH showed wider leaf area, produced more leaves during the cycle and had greater root weight.
