Abstract:

Fungicide resistance, whereby a mutation conferring reduced sensitivity to chemical control arises and spreads through a fungal population, severely inhibits the successful control of crop disease. Mathematical models play a vital role in assessing the risk of invasion of fungicide-resistant pathogens, and in the design of effective resistance management strategies. In this thesis, I investigate the factors affecting the invasion of resistance in heterogeneous crop environments. I develop a simple, nonlinear model for fungicide resistance which, improving on existing work, incorporates the dyn

Abstract:

This work was carried out to study the sensitivity of barley and wheat powdery mildew (<I>Erysiphe graminis </I>f.sp. <I>hordei</I> and <I>E. graminis </I>f.sp. <I>tritici</I> respectively) to morpholine fungicides. Morpholine fungicides are classified as compounds with a low risk of resistance development. On the other hand, barley and wheat powdery mildews belong to the group of high risk fungi as far as development of fungicide resistance is concerned. Firstly, mildew isolates collected in the UK were assessed, over the period 1992 to 1995, for their sensitivity to three morpholine fungicid

Two upland cotton varieties (Deltapine 5415 and SureGrow 125) were subjected to various seed fungicide treatments to determine seedling emergence and vigor in a Mohave Valley field prone to Rhizoctonia infection of cotton seedlings. During 1998, cotton seedlings in this field exhibited symptoms associated with Rhizoctonia, Pythium, and Thielaviopsis fungi. Of the treatments examined in this study, Baytan+Thiram+Allegiance or Baytan+Ascend+Allegiance cotton seed treatments provided superior seedling disease protection.

Within this vast production panorama, the Eurasian grapevine (Vitis vinifera L.) is the most cultivated species of grapevine due to the high quality of its grapes.

Abstract:

Phoma stem canker is a disease of oilseed rape (Brassica napus) caused by closely related plant pathogens Leptosphaeria maculans and L. biglobosa. It is an economically important disease, causing annual yield losses of approximately £770 million worldwide. When colonising oilseed rape, L. maculans and L. biglobosa exist in close proximity on the leaf, competing for resources as they move through the main leaf vein and into the stem. Fungicides are commonly used to decrease severity of phoma stem canker on oilseed rape. However, the efficacy and longevity of active chemicals is under threat fro

Recent observations indicate that V. inaequalis populations in Virginia have developed resistance to myclobutanil and other SIs.

Abstract:

Commercial development of the fungicide prochloraz for the control of pre- and post-harvest diseases in fruit crops has been restricted by the occasional occurrence of 'musty' taints. The primary aims of this research were to identify the cause of taint and and its means of formation. Sensitive and selective residue methodology based upon determination by gas chromatography with mass selective detection was devised, validated and used to establish 2,4,6-trichloroanisole (2,4,6-TCA) as the direct cause of taint by analysis of field-treated samples and studies involving 14C-radiolabelled prochlo

Thesis (MScAgric)--Stellenbosch University, 1998.<br>ENGLISH ABSTRACT: Eyespot is an important disease of spring wheat (Triticum aestivum L.). Four species of Ramulispora are associated with this disease, of which Tapesia yallundae and T. acuformis. are common. This thesis investigates the broader subjects of genetic variability, reproductive dynamics and fungicide resistance in Tapesia yallundae. Each of the chapters treats specific but related topics. T. yallundae, which is the only species thus far reported from South Africa, has been associated with yield losses of up to 50%. To ena
