“…The results obtained from this study using Afla-Guard in corn showed parallelism with the results of studies conducted in different countries on peanuts and corn using Afla-Guard, and it was seen that it could successfully solve the AF problem on a field basis. ,,, In a study conducted in Turkey for the biological control of AF contamination in peanuts in 2015, Afla-Guard was shown to give effective results . In this study, the researchers reported that AF concentrations were generally quite low in treated samples (between 0.04 and 0.71 μg/kg), and AFs were reduced by 97 to 99% compared with the controls.…”

Aflatoxins (AFs) are a family of mycotoxins produced by molds in agricultural products. To deal with this problem, one of the control methods is the biological solution using a non-pathogenic strain Aspergillus flavus NRRL 21882 (Afla-Guard). This study was conducted to evaluate the potential of A. flavus NRRL 21882 to control the AF contamination of corn in the field and during storage in 2018 and 2019. The experimental design consists of treatment at different vegetative stages of infested corn in the field trial. After the field has been harvested, half the corn kernels from both treated and control plots were treated with biopesticide; the other half of the kernels from each group were not treated and used as the control of the storage. Consequently, storage applications consisted of kernels: (1) not treated at all; (2) treated prior to storage; (3) field-treated; and (4) treated both in the field and prior to storage. After field trials, the AF content was very low in the treated plots, ranging from 0.50 to 1.04 μg/kg and from 0.50 to 0.73 μg/kg in 2018 and 2019, respectively, while the AF content in the control was 98.3 and 73.9 μg/kg in 2018 and 2019, respectively. After storage, corn kernels from field plots that were treated with the biopesticide (treated/control) showed low levels of AFs, even after they have been stored under conditions conducive to AF contamination. The biopesticide effect ranged from 98 to 99% and from 69 to 99% in the field and during storage, respectively. This paper has provided the first indications on AF biocontrol based on a competitive exclusion in the corn-growing region of Turkey. The data showed that spraying during the storage period did not provide any further prevention of AF contamination, and only treatment in the field had a significant effect on AFs that occurred in storage.

“…A second biocontrol product, Afla-guard ® , containing a different atoxigenic A. flavus isolate (NRRL21882) as an active ingredient, was registered with USEPA for use in maize and groundnut in the US [58]. The product Afla-guard ® is commercialized by Syngenta Crop Protection, Inc. (Greensboro, NC, USA) and has been used in experimental groundnut fields in Turkey [59].…”

Aflatoxin contamination of important food and feed crops occurs frequently in warm tropical and subtropical regions. The contamination is caused mainly by Aspergillus flavus and A. parasiticus. Aflatoxin contamination negatively affects health and trade sectors and causes economic losses to agricultural industries. Many pre- and post-harvest technologies can limit aflatoxin contamination but may not always reduce aflatoxin concentrations below tolerance thresholds. However, the use of atoxigenic (non-toxin producing) isolates of A. flavus to competitively displace aflatoxin producers is a practical strategy that effectively limits aflatoxin contamination in crops from field to plate. Biocontrol products formulated with atoxigenic isolates as active ingredients have been registered for use in the US, several African nations, and one such product is in final stages of registration in Italy. Many other nations are seeking to develop biocontrol products to protect their crops. In this review article we present an overview of the biocontrol technology, explain the basis to select atoxigenic isolates as active ingredients, describe how formulations are developed and tested, and describe how a biocontrol product is used commercially. Future perspectives on formulations of aflatoxin biocontrol products, along with other important topics related to the aflatoxin biocontrol technology are also discussed.

“…Synthetic pesticides are known have a negative effect to environment, human health, and natural enemies [6,7]. It has encouraged the researcher to developed of alternative non-synthetic pesticide to control chili diseases [8,9]. One of the alternative methods is developed a botanical pesticide [10,11].…”

Colletotrichum sp. and Phytophthora capsici are a causative diseases in chili, they are causing damage up to 50%. Inorganic pesticides are commonly used to treat the diseases, but there are many impacts to plant and consumers of chili. As an alternative, botanical pesticide such as Colletotrichum sp. and Phytophthora capsici are developed massively, since they are good for consumer health. The aim of this research was to evaluate the effectiveness of various botanical extract of Jatropha curcas, Toona sureni, Pangium edule, Syzygium aromaticum and Cymbopogon citratus L as natural antifungal against the Colletotrichum sp. and Phytophthora capsici. The results showed that the inhibition on colony development of Colletotrichum sp. and Phytophthora capsici tested was significant. Extract of P. edule inhibited of Colletotrichum sp. growth at 6 DAI up to 74.06% and P.capsici up to 24.03%. At the same times observation (6 DAI) C. citratus L extract inhibited up to 44.38% colony growth of Colletotrichum sp. and 86.82% colony of P. capsici. Extract of Syzygium aromaticum showed the perfect inhibition (100%) on mycelial growth for P. capsici and 91.71% for Colletotrichum sp. Whereas, J. Curcas and T. sureni extract showed insignificant effect for all fungal pathogen. We are presumed that it because the bioactive compound of the extract. In this research we found that the main compounds of S. aromaticum is eugenol up to 70.97% that we know as antimicrobial.
