Detecting coffee leaf rust with UAV-based vegetation indices and decision tree machine learning models

Computers and Electronics in Agriculture, 2021
Coffee leaf rust (CLR) is one of the most devastating leaf diseases in coffee plantations. By knowing the symptoms, severity, and spatial distribution of CLR, farmers can improve disease management procedures and reduce losses associated with it ...

Coffee tree growth and environmental acclimation

, 2018
In this chapter, some aspects of coffee growth and development as well as the recent advances in the environmental physiology of growth and production are reviewed. The information deals with both Coffea arabica and C. canephora, which together account for 99% of coffee bean production worldwide.

Boron translocation in coffee trees

Plant and Soil, 2006
Boron deficiency in coffee trees (Coffea arabica) is widespread, however, responses to B fertilizer have been erratic, depending on the year, method, and time of application. A better understanding of B uptake, distribution, and remobilization within the plant is important in developing a rational fertilization program. Field and greenhouse experiments

Redistribution of Fungicides in Coffee Trees

Experimental Agriculture, 1973
SUMMARYUsing coffee trees sprayed with cuprous oxide and captafol it has been shown that both fungicides are redistributed within the tree canopy by rain. Under conditions of light rain fungicides are removed from upper parts of trees and redeposited at lower levels within the canopy in amounts capable of providing effective protection against coffee ...

Shade tree Chloroleucon eurycyclum promotes coffee leaf rust by reducing uredospore wash-off by rain

, 2020
Shade trees stimulate many pathways that influence disease development in opposite directions, and that, in addition, may interact with environment.
