Investigations were carried out in 2007-2009 on the plots of the Felin Experimental Station belonging to the University of Life Science in Lublin. The studies comprised two cultivation lines of durum wheat (<i>Triticum durum</i> L.): STH 716 and STH 717, as well as the 'Tonacja' cultivar of common wheat (<i>T. aestivum</i> ssp. <i>vulgare</i> L.). Two levels of chemical protection were applied in the cultivation: minimal and complex protection. Infection of wheat roots and stem bases was recorded in each growing season at hard dough stage (87 in Tottman's scale, 1987). After three years of study, the mean disease indexes for the analyzed wheat genotypes in the experimental treatment with minimal protection were 31.13, 30.43 and 38.83 for, respectively, the 'Tonacja' cultivar and the cultivation lines of <i>T. durum</i> STH 716 and STH 717. In the experimental combination with complex protection, after three years of study the disease indexes ranged from 25.26 (<i>T. durum</i> STH 716) to 30.83 (<i>T. durum</i> STH 717). The results of mycological analysis of diseased plants showed that <i>Fusarium</i> spp., especially <i>F. culmorum</i>, <i>F. avenaceum</i> as well as <i>Bipolaris sorokiniana</i> and <i>Rhizoctonia solani</i>, caused root rot and necrosis of wheat stem bases. The analyzed chemical protection levels did not significantly influence grain yield of the investigated genotypes of <i>T. aestivum</i> and <i>T. durum</i>.

Natural Infestation

AbstractTwenty-five varieties of common wheat (Triticum aestivum L.) and 25 durum wheat (Triticum durum Desf.) grown in the Western Canadian Co-operative Tests were studied at Morden, Manitoba, in 1964, for their resistance to natural infestation by a spider mite, Tetranychus sinhai Baker. Some of these were heavily infested whereas others showed no infestation. The differences were statistically significant. Generally, the commonly grown varieties, such as, Selkirk, Thatcher, Ramsey, Stewart were resistant, but some of the hybrid varieties, such as Sask. 6070, Q2331-5 under test were susceptible.

Wheat Seeds

Wheat midge larvae, Sitodiplosis mosellana (Géhin), attack developing seeds and cause losses of common wheat, Triticum aestivum L., and durum wheat, Triticum durum Desf. (Olfert et al. 1985; Lamb et al. 1999). Insecticide applied as the crop flowers can reduce damage (Elliott 1988). The economic threshold varies from 4 to 7% of common wheat seeds infested by larvae, depending upon grade of wheat and cost of insecticidal control (Lamb et al. 2000). To make control decisions, farmers count adults at sunset during the period from heading to flowering (Elliott and Mann 1996), and apply insecticide if densities reach a nominal threshold of one adult per four or five wheat spikes (Anonymous 1993). Decisions must be made although no relationship has been detected between the number of adults in the crop and subsequent densities of damaging larvae (Oakley et al. 1998), and farmers have little confidence in their counts. The pest is difficult to sample because adults are small, short-lived, crepuscular, and are usually hidden in the crop canopy (Pivnick and Labbé 1993); eggs are microscopic (Mukerji et al. 1988); larvae feed inside florets (Lamb et al. 2000); and mature larvae and pupae are in the soil (Lamb et al. 1999). Sticky traps have been used to sample midges in sorghum (Merchant and Teetes 1992) and in wheat (Oakley et al. 1998), with mixed results. Our objective was to determine if catches of wheat midge adults on sticky traps can effectively guide farmers in making control decisions.
