摘要:The present invention relates to pesticidal compositions and methods for controlling plant pathogens, particularly basal stem rot in the oil palm primarily caused by Ganoderma species. The pesticidal compositions comprising, as active components: (A) Bioactive compound derived from a whole broth culture of an chitinolyic microorganisms, wherein the bioactive compound comprises any or any combination of: chitinolyic microorganism, whole cell broths, liquid cultures, spores, pure cultures, cell fraction, substances, suspensions, supernatants, filtrates, extract or a cell-free extract thereof or metabolite thereof or isolated compounds, wherein the bioactive compound is derived from at least one chitinolyic microorganisms that degrade chitinous substrates. The said chitinolytic microorganism is bacteria belonging to genus Bacillus, Streptomyces and/or fungal genus Trichoderma; (B) at least one organic acid; and (C) at least one pesticide selected from chemical pesticides, microbial pesticides, plant defense activators, cuticle degrading enzymes, cell wall synthesis inhibitors, bacteriocins, antifungal peptides, antimicrobial preservatives, plant oil or plant extract. More specifically, this invention envisions the use of bioactive compounds and/or metabolites from chitinolyic microorganisms in combination essentially of organic acid and the compositions comprising them, in the use form as fungicides and/or insecticides, also be present as 'booster' to other pesticides results in many cases in an expension of pesticidal spectrum of activity or in a prevention of pesticide resistance development. Furthermore, in many cases, synergistic effects are obtained. In various embodiments, the organic acid consists essentially of acetic acid, preferably acetic acid from a fermentation. The formulation is typically applied to agricultural soil or plant material. In a particular, the present invention can be used in combination with a carrier selected from the plant growth nutrient, organic fertilizer or inorganic/organic mixture fertilizer. Although the following description relates almost exclusively to managing basal stem rot (BSR) disease in oil palm primarily caused by Gonoderma species. It will be appreciated by those skill in the art that the invention could be used to treat other diseases and pests of other plants, includes but is not limited to a fungus, bacteria, actinomycete, virus, insects, Acari and/or nematodes.
