Abstract

The invention relates to the use of a compound of formula (I)

or salts thereof

for controlling coffee rust, citrus black spot, citrus scab or banana black sigatoka disease, and to corresponding methods.

First claim

The invention claimed is:

1. A method for treating plants in need of control of citrus scab or banana black sigatoka disease, consisting of applying to said plants or parts of said plants, to the seeds from which they grow or to the locus in which they grow, an effective amount for controlling the disease, of
(i) a compound N-(5-chloro-2-isopropylbenzyl)-N-cyclopropyl-3-(difluoromethyl)-5-fluoro-1-methyl-1H-pyrazole-4-carboxamide, or an agrochemically acceptable salt thereof, or
(ii) a composition consisting of N-(5-chloro-2-isopropylbenzyl)-N-cyclopropyl-3-(difluoromethyl)-5-fluoro-1-methyl-1H-pyrazole-4-carboxamide, or an agrochemically acceptable salt thereof, and one or more additives selected from the group consisting of extenders, solvents, diluents, dyes, wetting agents, dispersants, emulsifiers, antifoams, preservatives, secondary thickeners, stickers, gibberellins, and water,
wherein the citrus scab or banana black sigatoka disease is caused by a fungus selected from the group consisting of Elsinoe fawcettii and Mycosphaerella fijiensis , and
wherein (i) or (ii) is applied at an application rate of N-(5-chloro-2-isopropylbenzyl)-N-cyclopropyl-3-(difluoromethyl)-5-fluoro-1-methyl-1H-pyrazole-4-carboxamide, or an agrochemically acceptable salt thereof, from about 0.5 g/ha to about 6.25 g/ha.

2. The method according to claim 1 , wherein (i) or (ii) is applied to genetically modified cultivars, the seed thereof, or to cultivated areas on which these cultivars grow.

3. The method according to claim 1 , wherein (i) is applied.

4. The method according to claim 1 , wherein (ii) is applied.

5. The method according to claim 1 , wherein (i) or (ii) is applied by spray application.
