Problems solved by technology

[0005] However, no single fungicide is useful in all situations, and repeated use of a single fungicide often leads to the development of resistance to that fungicide or related fungicides

Embodiment

[0043] Representative synergies, including the application rates used and the resulting disease control results for wheat leaf rust and wheat spotted blight are presented in Table 1.

[0044] For mixture studies with compounds of formula I: Treatments consisted of fungicides comprising compounds of formula I and flufenapyr. Technical grade materials were dissolved in acetone to make stock solutions, which were then used to make 4-fold dilutions in acetone for each individual fungicide component or two-way mixture. After mixing dilution with 9 volumes of water containing 110 parts per million (ppm) Triton X-100, the desired fungicide ratio was obtained. The fungicide solution (20 milliliters (mL)) was applied to 12 potted plants using an automated booth sprayer utilizing a 20 pounds per square inch (psi) operating at a relative angle setting. Two 6218-1 / 4 JAUPM spray nozzles thus covering both surfaces of the leaves. All sprayed plants were allowed to air dry before further t...

Abstract

A fungicidal composition containing a fungicidally effective amount of (a) the compound of Formula I, (3S,6S,7R,8R)-8-benzyl-3-(3-((isobutyryloxy)methoxy)-4-methoxypicolinamido)-6-methyl-4,9-dioxo-1,5-dioxonan-7-yl isobutyrate, and (b) fluxapyroxad, provides synergistic control of selected fungi.

Description

[0001] Cross-references to related applications [0002] This application claims the benefit of U.S. Provisional Patent Application Serial No. 61 / 747,094, filed December 28, 2012, which is expressly incorporated by reference. Technical field [0003] The present invention relates to synergistic fungicidal compositions comprising (a) a compound of formula I and (b) fluxapyroxad. Background technique [0004] Fungicides are compounds of natural or synthetic origin that are used to protect plants from damage caused by fungi. Current agricultural methods rely heavily on the use of fungicides. In fact, some crops cannot be grown effectively without the use of fungicides. The use of fungicides allows growers to increase yields and crop quality, and thereby increase the value of the crop. In most cases, the increase in crop value is at least three times the cost of fungicide application. [0005] However, no one fungicide is useful in all situations, and repeated use of a sing...
