When seedlings areinfected with Fusarium, damping-off may occur.
Fusarium vasinfectum G.F.
(1978) Refusal of food contaminated with T-2 fusariotoxin.
(1985) Effect of cultural practices, soil phosphorus, potassium and pH on the incidence of Fusarium head blight and deoxynivalenol levels in wheat.
Only a few of the known trichothecenes have been found to contaminate food or animal feed including: deoxynivalenol (DON), nivalenol (NIV), diacetoxyscirpenol (DAS), and T-2 toxin and, less frequently, certain derivatives (3-Ac-DON, 15-Ac-DON, fusarenon-X and HT-2 toxin).
Vomiting factor from moldy corn infected with Fusarium spp.
The doses that produced 50% inhibition of 3H-thymidine uptake in mitogen-stimulated human lymphocytes for fusarenon-X, NIV, DON, and 15-AcDON were 18, 72, 140, and 240 ng/ml, respectively.
The diarrhoea induced by ip admin-istration of 1.0 mg fusarenon/kg in male Wistar rats was not mediated by the cyclic nucleotide system as the mycotoxin did not increase the cyclic GMP and AMP contents in the intestinal mucosa (Matsuoka & Kubota, 1987).
Fusarium wilt disease is caused Fusarium oxysporum f
Disinfested soil was quickly contaminated by certain pathogens ( Fusarium and Pythium spp.) and there was also a possibility of reinfection from the lower layer of soil not reached by the fumigant.
When the mice were fed a diet containing 5, 10, or 20 mg fusarenon-X/kg throughout the gestation period or in the early stages of gestation, the mycotoxin inhibited embryonal implantation.

AgroAtlas - Diseases - Fusarium oxysporum f
Humans carry proteins needed for survival and are used for metabolization, fighting infections, and behavior factors.
Pea plants infected with Fusarium oxysporum
The data indicate that crops parasitized by Fusarium species will probably be contaminated with these mycotoxins.
Evaluation of Fungicides for Control of Fusarium Wilt …
(1984) Detection of T-2 toxin in Fusarium sporotrichioides-infected corn by enzyme-linked immunosorbent assay.
Evaluation of Fungicides for Control of Fusarium Wilt ..
The potential for the production of a number of trichothecenes among Fusarium species is well documented, and the toxicology of a few trichothecenes and the natural occurrence of some of these compounds in food is fairly well established.
against five isolates of Fusarium oxysporum f
There is no evidence from the published long-term toxicity studies in animals to indicate that T-2 toxin, fusarenon-X, and NIV are tumorigenic in animals.
