Dear Francis,

Efficacy of Ampelomyces quisqualis and 1,2 dibromo chloro propane in suppression of Erysiphe pisi in peas (Pisum sativum)

Dibromo chloro-propane was used as a nematocide or soil fumigant. Its no longer being used.  Where will you get it?

It has been reported to cause low sperm count.  Be careful. You may never have children.

Its better you do this work as an MSc project where you will have time to implement the control (precautions) of your inputs (i.e., bio agents) & not a BSc project.

See brief below.

Ampelomyces quisqualis
(Deuteromycetes)

by David Gadoury, Department of Plant Pathology, Cornell University-NYSAES, Geneva NY

The fungus Ampelomyces quisqualis is a naturally occurring hyperparasite of powdery mildews. It infects and forms pycnidia (fruiting bodies) within powdery mildew hyphae, conidiophores (specialized spore-producing hyphae), and cleistothecia (the closed fruiting bodies of powdery mildews). This parasitism reduces growth and may eventually kill the mildew colony. A. quisqualis has been the subject of numerous investigations on biological control of powdery mildews for over 50 years.

1,2-Dibromo-3-chloropropane (DBCP) was used in the past as a soil fumigant and nematocide on crops; it is no longer used except as an intermediate in chemical synthesis. Acute (short-term) exposure to DBCP in humans results in moderate depression of the central nervous system (CNS) and pulmonary congestion from inhalation, and gastrointestinal distress and pulmonary edema from oral exposure. Chronic (long-term) exposure to DBCP in humans causes male reproductive effects, such as decreased sperm counts. Testicular effects and decreased sperm counts were observed in animals chronically exposed to DBCP by inhalation.

Best regards.
