preparation example Construction

[0033] Representative organic liquids that may be employed in the preparation of the emulsifiable concentrates of the present invention are aromatic liquids such as xylene and propylbenzene fractions; or mixed naphthalene fractions, mineral oils, substituted aromatic organic liquids such as phthalates Dioctyl formate; kerosene; dialkylamides of various fatty acids, especially dimethylamides of fatty diols and diol derivatives such as n-butyl, ethyl or methyl ethers of diethylene glycol Ether and methyl ether of triethylene glycol, etc. Mixtures of two or more organic liquids are also suitably employed in the preparation of emulsifiable concentrates. Preferred organic liquids are xylene and propylbenzene fractions, with xylene being most preferred. Surface active dispersants are typically employed in liquid formulations and are present in an amount of 0.1 to 20 wt%, based on the combined weight of the surface active dispersant and synergistic composition. The formulations may...

[0047] Fungicide mixture against spot blight of wheat (Gremina graminearum; anamorph: Septoria tritici; Bayer coded as: SEPTTR) evaluation of therapeutic agent and protective agent activity

[0048] Wheat plants (var. Yuma) were grown from seed in a greenhouse in plastic pots with a surface area of ​​27.5 square centimeters (cm2) containing a 50% mineral soil / 50% soilless Metro mix, 8-12 seeds per pot. The plants were used for testing when the first leaves had fully emerged (this usually required 7 to 8 days after planting). The test plants were inoculated with an aqueous spore suspension of Septoria tritici 3-days before (3-day treatment test; 3DC) or 1-day after (1-day protectant test; 1DP) of fungicide treatment. After inoculation, the plants were kept at 100% relative humidity (1 day in a dark dew chamber, then two days in a lighted mist chamber) to allow spores to germinate and infect the leaves. The plants were then transferred to the greenhouse until the disease ha...

Abstract

A fungicidal composition containing a fungicidally effective amount of a) a compound of Formula I and (b) at least one fungicide selected from the group consisting of epoxiconazole, prothioconazole, azoxystrobin, pyraclostrobin, penthiopyrad, isopyrazam, bixafen, boscalid, chlorothalonil and isobutyric acid (3S,6S,7R,8R)-8-benzyl-3-[(3-isobutyryloxymethoxy-4-methoxypyridine-2-carbonyl)-amino]-6-methyl-4,9-dioxo-[1,5]dioxonan-7-yl ester 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 61 / 249,475, filed October 7, 2009, which provisional application is expressly incorporated by reference into this application. Technical field [0003] The present invention relates to synergistic fungicidal compositions containing (a) a compound of formula I, and (b) at least one fungicide selected from the group consisting of epoxiconazole, prothioconazole, and azoxystrobin. esters, pyraclostrobin, pyritiostrobin, isopyrazam, bixafen, nicotinamide, chlorothalonil and isobutyric acid (3S,6S,7R,8R)-8-benzyl-3-[(3-isobutyryl Oxymethoxy-4-methoxypyridin-2-carbonyl)-amino]-6-methyl-4,9-dioxa-[1,5]dioxacyclononan-7-yl ester . 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...
