“…The use of formulations based on plant extracts (which have bioactive substances capable of acting as resistance inducers) has been subject to intense research (Costa et al, 2017). Guimarães et al (2016) verified that the application of Greenforce CuCa (formulation based on the by-products of the coffee industry supplemented with copper and calcium) and acibenzolar-S-methyl (ASM) reduced the incidence of BYS by 38% and 35%, respectively.…”

The use of resistance inducers is a promising development in the management of plant diseases, owing to their ability to control a broad spectrum of pathogens and improve the efficacy of fungicides. This study evaluates different sources of phosphonates (potassium, manganese, copper), a formulation prepared from the by‐products of the coffee industry (Greenforce CuCa), as well as the effects of their application, alone or in association with fungicide, in the management of two important coffee fungal diseases in Brazil: leaf rust and brown eye spot, caused by Hemileia vastatrix and Cercospora coffeicola, respectively. The effect of these products on defoliation, productivity and chemical composition of coffee beans (content of trigonelline, chlorogenic acid, caffeine and total soluble solids) was evaluated. Among all the alternative products tested individually, potassium phosphonate (P2O5—33.6% + K2O—29%) stood out, particularly for rust control, which was similar to the results of fungicide treatments. Treatments with fungicide, Greenforce CuCa and cuprous oxide, individually, caused less plant defoliation. Regarding the chemical composition of the coffee beans, the manganese phosphonate treatment showed the highest values for trigonelline, chlorogenic acid, caffeine and total soluble solid content. The results of this study show that resistance inducers can be useful in disease management, may come to eventually replace traditional fungicides and can also contribute to the beverage quality.

“…The highest mean observed was for the control treatment, with levels of 7.48 % of severity. Costa et al (2017) evaluated the effects of chemical products on the severity of bacterial leaf spot in passion fruit and showed that treatments with copper oxychloride limit the number of colonyforming units of Xanthomonas axonopodis pv. Passiflorae.…”

Xanthomonas vasicola pv. vasculorum is one of the main bacterial diseases in corn, which causes damage to crops due to its fast dissemination and difficult control. This study aimed to evaluate the effects of chemical products on its control and corn grain yield. The experimental design was randomized blocks, in a 2 x 7 factorial arrangement, with three replications. The first factor consisted of the corn hybrids P30F53VYHR (more resistant to the disease) and P4285VYHR (more susceptible) and the second one of six active ingredients (kasugamycin, sulfur, cuprous oxide, copper oxychloride, quaternary ammonia and potassium phosphite) and one control (no application). The obtained data were used to estimate the area under the disease progress curve. The products based on quaternary ammonia, cuprous oxide, copper oxychloride and kasugamycin provided a greater disease control. P30F53VYHR presented a higher grain yield than that for P4285VYHR. Therefore, the use of a genetically resistant hybrid is an efficient alternative for the management of this bacteriosis.
