High relative humidity conditions in the crop canopy are frequently essential for effectiveness of the control. Environmental aspects may as well have a crucial role in the fungal success. Non-target death in beneficial insects’ populations may have negative impacts on the achievement of the overall program of biological control. The wide host range of fungi may at times be a trouble, particularly when beneficial insects are there in a crop. High spores concentrations are frequently required in order to get sufficient pests control in a crop, and this can reduce the effectiveness of cost of fungal products.
Fungi have comparatively wide host range and, therefore, there can be an achievement of control of a number of pests using one product. This is mainly factual in control strategies of insects (Jackson, 1997).Ī number of commercial products of fungi are developed as spores that are easily adjusted to existing technology of application, for example, spray rigs. Fungi possess the possibility to create pan epidemic in the population of the host. The accessibility of many pathogenic fungi for insects and weeds control is another benefit to the commercial utilization of these organisms as biological control agents. Stability and tolerance to desiccation as a dry preparation are a total condition for commercial application. Sclerotial propagules or spores of fungi are usually more stable as compared to cells of bacteria. Due to this benefit that fungi possess as well as the large number of pathogenic fungi of weeds, a list of agents of biological control under evaluation for weed control named 22 fungi and no bacteria (Jackson, Schisler, Slininger, Boyette, & Silman, 1996).įungi have propagule stability. Spores of fungi are able to germinate as well as penetrate a healthy insect or weed and without the need to a compromise the defense of the host. Fungi have the ability to actively infect and cause death to the weed or insect host. There are several advantages related to the use of fungi for biological control. The most important fungi are the ones that are utilized as biological control agent (Jackson, Schisler, Slininger, Boyette, & Silman, 1996). Some groups of fungi are utilized successfully for crops protection from various pests.
A number fungi lead to annihilating crops diseases as others are crops themselves such as mushrooms.
