Abstract

The present invention relates to compositions and methods for disease control in plants. The compositions for use in the methods of the invention include glyphosate as the active compound. In addition, methods and compositions are disclosed to prevent and treat pest infection in glyphosate tolerant plants.

Claims

1. A method for treating leaf rust disease in a soybean or corn plant or wilt disease in a cotton plant comprising,

identifying a soybean or corn plant as being infected with a rust pathogen, or a cotton plant as being infected with a wilt pathogen;

and

applying a composition having glyphosate to said soybean, corn, or cotton plant or portion thereof, further wherein the composition comprises at least one fungicide selected from the group consisting of;

a strobilurin and epoxiconazole;

whereby said composition results in said disease being controlled.

2. The method of claim 1, wherein the strobilurin is pyraclostrobin.

3. A method of controlling weeds and Soybean Rust disease in a field of glyphosate tolerant soybean plants, weeds and corn rust in a field of glyphosate tolerant corn plants, or weeds and cotton wilt disease in a field of glyphosate tolerant cotton plants, said method comprising,

identifying a soybean or corn plant as being infected with a rust pathogen, or a cotton plant as being infected with a wilt pathogen

applying a first composition to the field, comprising a first glyphosate composition comprising an effective amount to control said weeds;

and

applying a second composition to the field, comprising an effective amount of a second glyphosate composition, whereby said second composition comprises a fungicide containing pyraclostrobin and epoxiconazole and controls said disease of said plants.

4. A method of controlling weeds and Soybean Rust disease in a field of glyphosate tolerant soybean plants, said method comprising,

identifying a soybean plant as being infected with Soybean Rust;

applying a first composition to the field, comprising a first glyphosate composition comprising an effective amount to control said weeds; and

applying a second composition to the field, comprising an effective amount of a second glyphosate composition, wherein said second composition also comprises at least one fungicide selected from the group consisting of;

a strobilurin and epoxiconazole; and

controls said disease of said plants.

5. The method of claim 4, wherein the strobilurin is pyraclostrobin.
