Risk of Disease Occurrence in Soybeans

Description

Calculation of the Risk of Disease Occurrence in Soybeans as a Function of Variables meteorological variables (Engers et al., 2024).

Usage

risk(DAY, MONTH, AAT, RH, disease = "rust", verbose = FALSE, plot = FALSE)

Arguments

DAY

The column for the day of the month.

MONTH

The column for the month of the year (numeric value).

AAT

The average air temperature column (in degree Celsius).

RH

The relative humidity column (in %).

disease

Define the soybean disease (Standard = 'rust').

verbose

Logical argument. Runs the code silently if FALSE.

plot

Plot a graph of the accumulation (Default is F (FALSE)).

Value

Returns the parameters of the incidence probability of the selected disease in the soybean crop, being:

* RHrisk
Risk caused by relative humidity.

* TEMPrisk
Risk caused by air temperature.

* TOTALrisk
Product of the multiplication between RHrisk and TEMPrisk.

* RELrisk
Relative risk obtained from the highest value of TOTALrisk.
