Abstract
A method controlling an agricultural sprayer includes identifying an herbicide to be sprayed using the agricultural sprayer, determining a geoposition associated with the agricultural sprayer within a field, determining if crop planted at the geoposition is tolerant to the herbicide using as-planted data, and if the crop is not tolerant of the herbicide, preventing herbicide spraying operations while the agricultural sprayer is at the geoposition. An agricultural sprayer adapted for performing the method is also provided.
Claims20
A method for controlling an agricultural sprayer, comprising:
- identifying an herbicide to be sprayed using the agricultural sprayer;
- determining a geoposition of a crop associated with the agricultural sprayer within a field;
- receiving herbicide resistance data associated with the crop at the determined geoposition associated with the agricultural sprayer;
- determining, via sprayer control hardware, if the crop planted at the geoposition associated with the agricultural sprayer is tolerant to the identified herbicide to be sprayed using as-planted data and the received herbicide resistance data associated with the crop;
- if the crop is determined not to be tolerant of the herbicide, preventing spraying of the herbicide while the agricultural sprayer is at the geoposition.

A method comprising:
- receiving as-planted map data for a land area, the as-planted map data identifying a first boundary associated with planting of a first hybrid or variety of seed, and a second boundary associated with planting of a second hybrid or variety of seed;
- identifying a planter fill event associated with the as-planted map data occurring between the planting of the first hybrid or variety of seed and the planting of the second hybrid or variety of seed;
- identifying a mix area in the land area containing both the first hybrid or variety of seed and the second hybrid or variety of seed;
- producing an herbicide application map to prescribe spraying an identified herbicide within the first boundary if the first hybrid or variety of seed is genetically resistant to the herbicide, within the second boundary if the second hybrid or variety of seed is resistant to the herbicide, and within the mix area if both the first hybrid or variety of seed and the second hybrid or variety of seed are genetically resistant to the herbicide;
- determining a geoposition of a crop located within at least one of the first boundary, the second boundary, or the mix area and
- determining, via sprayer control hardware, whether or not to apply the identified herbicide at the geoposition associated with a crop based on the genetic resistance of the crop indicated in the herbicide application map.

A method for controlling an agricultural sprayer, comprising:
- identifying an herbicide to be sprayed using the agricultural sprayer;
- determining a geoposition of a crop associated with the agricultural sprayer within a field;
- determining control hardware, whether or not to apply the identified herbicide to be sprayed at the geoposition of the crop according to an herbicide application map that indicates an herbicide resistance of the crop at the determined geoposition;
- wherein the herbicide application map is produced by:
- receiving as-planted map data for a land area, the as-planted map data identifying a first boundary associated with planting of a first hybrid or variety of seed, a second boundary associated with planting of a second hybrid or variety of seed,
- identifying a planter fill event associated with the as-planted map data occurring between the planting of the first hybrid or variety of seed and the planting of the second hybrid or variety of seed,
- identifying a mix area in the land area containing both the first hybrid or variety of seed and the second hybrid or variety of seed,
- producing the herbicide application map to prescribe spraying the identified herbicide within the first boundary if the first hybrid is genetically resistant to the herbicide, within the second boundary if the second hybrid is resistant to the herbicide, and within the mix area if both the first hybrid and the second hybrid are genetically resistant to the herbicide.

An agricultural sprayer comprising:
- a sprayer control system electrically connected to a plurality of valves for controlling application of an herbicide to a land area;
- a GPS receiver electrically connected to the sprayer control system for providing a geoposition associated with a crop to the sprayer control system;
- wherein the sprayer control system is configured to:
- receive as-planted data for the land area, the as-planted data identifying a first boundary associated with planting of a first hybrid or variety of seed and a second boundary associated with planting of a second hybrid or variety of seed,
- identify a planter fill event associated with the as-planted data occurring between the planting of the first hybrid or variety of seed and the planting of the second hybrid or variety of seed,
- identify a mix area in the land area containing both the first hybrid or variety of seed and the second hybrid or variety of seed,
- determine whether the crop associated with the geoposition is genetically resistant to the herbicide to be applied based on whether the geoposition is within the first boundary, the second boundary, or the mix area;
- and
- control the spraying of the herbicide at the geoposition associated with the crop based on the determination of whether the crop is genetically resistant to the herbicide.
6 more elements
A method, comprising:
- identifying an herbicide to be applied;
- determining a geoposition of a crop;
- receiving herbicide resistance data associated with the crop at the determined geoposition;
- determining, via sprayer control hardware, if the crop at the geoposition is tolerant to the identified herbicide to be applied using as-planted data and the received herbicide resistance data associated with the crop;
- and
- if the crop is determined not to be tolerant of the herbicide, preventing application of the herbicide at the geoposition.
