tdelta: Optimum conditions for pesticide application

In EstimateBreed: Estimation of Environmental Variables and Genetic Parameters

Optimum conditions for pesticide application

Description

Determining the ideal time for pesticide application using TDELTA

Usage

tdelta(
  LON,
  LAT,
  type = 2,
  days = 7,
  control = NULL,
  details = FALSE,
  verbose = TRUE,
  dates = NULL,
  plot = FALSE
)

Arguments

LON	Longitude (in decimal)
LAT	Latitude (in decimal)
type	Type of analysis. Use 1 for forecast and 2 for temporal data.
days	Number of days (only use this argument if type=1).
control	Type of product to be applied. Use 'fung' for fungicide, 'herb' for herbicide, 'ins' for insecticides, 'bio' for biological products.
details	Returns the result in detail if TRUE.
verbose	Logical argument. Runs the code silently if FALSE.
dates	Only use this argument if type=2. Start and end date for obtaining weather data for a crop cycle.
plot	Logical argument. Plots a graphic if 'TRUE'.

Value

Returns the ideal application times, considering each scenario. Taking as a parameter a TDELTA between 2 and 8, wind speed between 3 and 8, and no precipitation.

Examples

library(EstimateBreed)

# Forecasting application conditions
forecast <- tdelta(-53.6969,-28.0638,type=1,days=10,verbose=TRUE)

# Retrospective analysis of application conditions
retrosp <- tdelta(-53.6969,-28.0638,type=2,days=10,
                 dates=c("2023-01-01","2023-05-01"),
                 verbose=TRUE)
