“…non-target mortality, the current tendency is to enhance specificity of control techniques.The problem of accidental by-kills of non-target species is a recurring theme in biological conservation, as exemplified in reviews in quite distinct fields such as risk related to fungi used to control plant diseases (Brimner & Boland 2003), chemical substances against introduced lamprey in American lakes (Sullivan et al 2003), organophosphate spraying to control the red-billed quelea (Quelea quelea) in Africa (McWilliam & Cheke 2004), brodifacoum used to control invasive mammal species (Eason & Spurr 1995;Murphy et al 1998), and biological control in general (Simberloff & Stiling 1996).…”

Introduced vertebrate predators are one of the most important threats to endemic species throughout a range of ecosystems, in particular on islands in biodiversity hot spots. Consequently, the reduction of predator numbers is considered a key conservation action in the management of many native vertebrates vulnerable to predators. It is now established that control attempts may affect non-target species through trophic interactions, but little is known concerning their consequences on competitive relationships. We study a mathematical model mimicking the effects of controlling introduced species in the presence of their competitors.We used two competing rodents to illustrate our study: black rats, Rattus rattus, and mice, Mus musculus. Analyses of the model show that control of only one introduced species logically results in the dramatic increase of the overlooked competitor. We present empirical data that confirm our theoretical predictions. Less intuitively, this process, which we term 'the competitor release effect', may also occur when both introduced competitors are simultaneously controlled. In our setting, controlling both predators can promote their coexistence. This occurs as soon as the inferior competitor benefits from the differential effect of the simultaneous control of both competitors, that is, when the indirect positive effect of control (the removal of their competitors) exceeds its direct negative effect (their own removal). Both control levels and target specificity have a direct influence on the extent of this process: counter-intuitively, the stronger and more specific the control, the greater the effect. The theoretical validation of the competitor release effect has important implications in conservation, especially for control management.

“…Similarly, a total of14 isolates of T. harzianum were tested, only three isolates such as H-10, H-12 and H-21 were considered as high potential and the isolate H-6 was considered as low potential based on the specific activity of the enzymes. There are many reports demonstrating that cellulase, β-1,3glucanase, β-1,4glucanase, chitinase and proteases are effective features associated with the ability of Trichoderma to control plant pathogens (Brimner et al, 2003;Haran et al, 1996;Wang et al, 2003;Lorito et al, 1994).…”

Wilt desease of banana caused by Fusarium oxysporum f.sp. cubense (FOC) is one of the most destructive deseases of banana in the tropics. Actinomycetes are the most economically and biotechnologically valuable prokaryotes able to produce wide range of bioactive secondary metabolites. The aims of the present study are to isolate and screen the actinomycetes with high potential ability to produce secondary metabolites that have inhibitory activity against plant pathogenic fungi, Fusarium oxysporum f. sp. cubense. Two isolates from Lampung and Cianjur showed activity against fungi. The isolates designed as L.3.1 and CiIA5b. The metabolites from potent stain was produced by extraction of culture filtrate with ethyl acetate : methanol (4 : 1), it was tested for their antifungal activity by well diffusion method. Evidence for in vitro antibiosis of L.3.1 and CiIA5b isolates was demonstrated by the zone of fungal-growth inhibition. Production of secondary metabolites was analysis by thin layer chromatography (TLC) and bioautography assays. In this study, the metabolites from L.3.1 and CiIA5b have showed good antifungal activity.
