Nickelfll) complexes of p-anisaldehyde thiosemicarbazone, [Ni(HL)2X2] with X = Cl [212], Br [213], showed greater activity than the corresponding ironfll), manganesefll) and cobalt(II) complexes against Alternaria (Sp.), Paecil-omyces (Sp.) and Pestalotia (Sp.). All complexes were more active than the uncomplexed thiosemicarbazone.

Saprophytic, dark pigmented fungi such as Alternaria spp. can infect a wide range of plant species, especially tissues that are exposed to other biotic or abiotic stressors and older and senescing plant tissues. Also, wet weather conditions favour attack by Alternaria spp. Inoculum of Alternaria and potentially production of altemariol is further enhanced when cereal straw and stubble is left on the soil surface and not sufficiently incorporated into the soil after harvest (direct seeding and minimum tillage systems).

Early blight, Alternaria solani Kuhn., is a problem in some areas, particularly in. warmer climates where potato growth is not optimum. Control can be obtained by protective sprays, particularly with the organics that have been recommended for late blight control.
