tdelta: 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
)

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.

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.
