Perlakuan lama kebasahan terdiri dari 0, 3, 6, 9, atau 12 jam dan aplikasi dilaksanakan pada pagi atau sore hari. Hasil penelitian menunjukkan bahwa penyakit yang ditimbulkan oleh Fusarium sp. pada eceng gondok lebih parah dan berkembang lebih cepat ketika eceng gondok dipaparkan pada suhu yang lebih tinggi segera setelah inokulasi, dan tidak tergantung pada lama kebasahan ketika diaplikasikan pada pagi hari. Jamur ini tidak dapat menginfeksi beberapa tanaman budidayam sehingga aman digunakan sebagai agen pengendali hayati gulma eceng gondok.

Percobaan ini merupakan percobaan faktorial dengan dua faktor yaitu umur teki saat inokulasi dan penggunaan jamur patogen sekunder. Percobaan dirancang mengunakan Rancangan Acak Lengkap dengan 6 kali ulangan. Hasil menunjukkan bahwa jamur patogenik sekunder yang paling umum ditemukan berasosiasi dengan gulma teki yang terinfeksi jamur karat adalah Curvularia sp., Aspergillus sp. dan Fusarium sp. Jamur patogenik sekunder dapat meningkatkan kemampuan biokontrol jamur karat yang ditunjukkan oleh semakin meningkatnya intensitas penyakit yang terjadi pada gulma teki, berkurangnya jumlah umbi teki yang terbentuk dan terhambatnya pertumbuhan gulma teki.

A range of spore germination temperatures as well as dew period durations and temperatures were investigated to determine some of the environmental requirements for disease establishment and disease progress. Plants were inoculated with urediniospores and exposed to dew periods between 3 to 12 h at temperatures of 10, 15, or 20°C. For disease expression, the inoculated plants were then grown in a glasshouse at one of two temperature regimes (30/26°C or 18/13°C; day/night). Urediniospores germinated best at 12 ± 1°C, with lower germination rates at 5°C or above 20°C. No infection occurred when the plants were exposed to dew periods of ≤3 h, regardless of the incubation temperature. The disease progressed most rapidly when plants were inoculated and incubated for a dew period of at least 12 h at a temperature of 15 ± 1°C. The disease progressed most slowly following inoculation at dew periods of 6 h or less. Disease progress was more rapid when the plants were exposed to a cool-temperature regime (18/13°C) than when exposed to a warm-temperature regime (30/26°C). This suggests that good infection of parthenium weed could be obtained when the urediniospores arrive on the plants during the afternoon in the cooler months of the central Queensland autumn when relatively long dew periods are expected.

A 2 x 3 factorial experiment was arranged in a completely randomized design with six replicate plants in each treatment. The experiments consisted of one parthenium weed plant grown together with either 1, 2 or 3 buffel grass plants that are the same age as the parthenium weed plant (non-established treatments) or grown together with either 1, 2 or 3 buffel grass plants that are 20 days older than the parthenium plant (established treatments). The results showed that the disease progress of P. abrupta var. partheniicola increased as the competitor density decreased. The early establishment of the competitors did not affect the rate of disease progression. Above grown biomass of inoculated plants decreased as the density of the buffel grass plants increased. The greatest impact of competition working together with the rust in suppressing parthenium weed was observed on the reduction in seed production (98%). The biggest component of this reduction was due to competition rather than infection by the rust.

The study also investigated the combined effect of the infection and the competitor plant, i.e. buffel grass (Cenchrus ciliaris L.), a pasture species usually found in the weed habitat in Central Queensland. The 2 x 3 factorial experiment was arranged in a completely randomized design with six replicates in each treatment. The parthenium weeds were planted with or without buffel grass. The plants were inoculated with P. abrupta var. partheniicola urediniospores either at the rosette, flowering or mature growth stage of development. As controls, an additional six non inoculated plants with and without buffel grass were planted. The results showed that P. abrupta var. partheniicola affected more on the younger plants than on the older ones. Its infection decreased the plant height. A higher reduction in plant above ground biomass was recorded because of the rust when the plants were inoculated at the rosette growth stage of development in the presence of competition. The impact of the rust was greatest on the ability of parthenium to produce seeds.
