Abstract
The present invention relates to the control of harmful organisms which may appear during the cultivation of crop plants. The control is effected on the basis of the prediction of subarea-specific infestation risks.
Claims15
A method for the control of harmful organisms in a field in which crop plants are grown, wherein the method comprises the following steps:
- (A) creating a first infestation map, wherein in the first infestation map subareas in the field are indicated in which an infestation with harmful organisms has been observed in a past cultivation period,
- (B) creating a second infestation map, wherein in the second infestation map subareas in the field are indicated in which an infestation with harmful organisms has been observed in a current cultivation period, and
- (C) determining subarea-specific prediction of the infestation risk to the crop plants with harmful organisms for the current cultivation period, wherein the prediction is made based on the first infestation map and/or the second infestation map, and wherein the prediction is further based on subarea-specific information of a state of development of the crop plants, subarea-specific environmental factors, and/or weather information, and
- (D) creating a treatment map, wherein the treatment map indicates which subareas of the field are to be treated in order to prevent the dispersal of the harmful organisms and/or to control harmful organisms, wherein the treatment map is further created based on:
- the prediction of the infestation risk for the current cultivation period, and
- the treatment map is optionally created and/or adapted based on conditions predicted for a time of a planned treatment with regard to:
- weather, a development state of the crop plant, and/or environmental factors, and
- (E) treating subareas of the field in accordance with the treatment map.
A system for the control of harmful organisms in a field in which crop plants are grown, comprising
- (A) a first infestation map, wherein in the first infestation map subareas in the field are indicated in which in a past cultivation period an infestation with harmful organisms has been observed,
- (B) a second infestation map, wherein in the second infestation map subareas in the field are indicated in which an infestation with harmful organisms has been observed in the current cultivation period, and
- (C) means for predicting the infestation risk to the crop plants with harmful organisms for the current cultivation period, wherein the prediction is made based on:
- the first infestation map and/or the second infestation map,
- the subarea-specific information of a state of development of the crop plants and/or subarea-specific environmental factors, and
- weather information, and
- (D) means for creating a treatment map, wherein the treatment map indicates which subareas of the field are to be treated in order to prevent the dispersal of the harmful organisms and/or to control harmful organisms, wherein the treatment map is created based on:
- the prediction of the infestation risk for the current cultivation period, and
- the treatment map is further optionally created and/or adapted
- based on the conditions predicted for a time of a planned treatment with regard to weather, a development state of the crop plant, and/or environmental factors, and
- (E) optionally:
- a means for treating the subareas of the field in accordance with the treatment map.
A computer program product comprising:
- a computer-readable data storage device,
- program code which is stored on the data storage device, and which when run on a computer causes the computer to read one or more digital infestation maps into the working memory of the computer, wherein in the one or more infestation maps, subareas in the field indicate that a past cultivation period with harmful organisms has been observed, and/or an infestation with harmful organisms in a current cultivation period has been observed,
- the program code further causing the computer to calculate subarea-specific risks for an infestation of the crop plants with harmful organisms for the current cultivation period, wherein the calculation is made based on the following information:
- the digital infestation map(s),
- subarea-specific information of a state of development of the crop plants,
- subarea-specific environmental factors, and/or
- weather information,
- the program code further causing the computer to create a digital treatment map and output it in digital form to a user, wherein the treatment map indicates which subareas of the field are to be treated in order to prevent the dispersal of the harmful organisms and/or to control harmful organisms, wherein the treatment map is further created based on a prediction of the subarea-specific infestation risks for the current cultivation period, and
- optionally, the treatment map is created and/or adapted based on conditions predicted for a time of a planned treatment of the subareas with regard to:
- weather, a development state of the crop plant, and/or environmental factors.
A treatment map, wherein the treatment map indicates which subareas of a field for the cultivation of a crop plant are to be treated with a plant protection agent in order to prevent the dispersal of the harmful organisms and/or to control harmful organisms, wherein the treatment map has been created based on a subarea-specific prediction of the infestation risk of the field with one or more harmful organisms for a current cultivation period, and optionally, the treatment map has been created and/or adapted based on conditions predicted for a time of the planned treatment with regard to weather, a development state of the crop plant, and/or environmental factors.
