Fertilizer application may substitute, or at least reduce, the demand for chemical disease control in some cases, but may increase the demand in others. These interactions are illustrated in Fig. for winter wheat naturally infected by yellow rust. In temperate climates, high N application rates to winter wheat early in the growing season. rates, and applied lime on wheat grain yield and take-all disease in winter wheat. MATERIALS AND METHODS One ﬁeld experiment was initiated in the fall of to evaluate the effects of Cl fertilizer sources and rates on wheat grain yield and take-all EFFECT OF CHLORIDE FERTILIZERS .
Stripe Rust. Stripe rust or yellow rust is caused by a fungal pathogen, Puccinia striiformis f. sp. tritici and infection and disease progress is favored by cooler temperatures and wet conditions (at least 8 hours of leaf wetness). We are still experiencing cooler nights (stripe rust development. Stripe rust thrives in cool and damp conditions, which have not been prevalent in winter wheat country yet this spring. If conditions turn cool and damp - like they did in - stripe rust could spread. Incidentally, those are also the conditions that maximize winter wheat yield.
The average yields of winter wheat achieved by Irish growers are amongst the highest globally. This is facilitated by the mild, wet climate and long summer days which results in slow crop development, and a long grain filling period rarely affected by drought. The crops development through its growth stages.

For example, Shefelbine, Mathre, and Carlson found that chloride‐containing fertilizer application can control common root rot in barely, and Scheyer, Christensen, and Powelson revealed its effects on stripe rust development in winter : Lili Yang, Zhijun Zhu, Jinshui Zhang, Yimin Gao, Xingmei Wang, Gaoyuan Liu, Na Li, Long Ma, Yan‐an T.
Chloride Fertilizer Effects on Stripe Rust Development in Winter Wheat by Joyce Mack Scheyer A THESIS submitted to Oregon State University in partial fulfillment of the requirements for the degree of Master of Science Completed Commencement June that chloride-containing fertilizer application can control common root rot in barely, and Scheyer, Christensen, and Powelson () revealed its effects on stripe rust devel-opment in winter wheat.
In addition, Fixen et al. () suggested that chloride is an important osmoticum in higher. effect on development of stripe rust. The graph below shows the rate at which stripe rust can develop each month for some locations in the wheat belt.
For the main wheat belt, temperatures are ideal for stripe rust in the autumn and spring and it can have over 2 cycles per month at those times.
Its rate of development drops to less than. The interpretation of the Cl test and corresponding fertilizer recommendations for wheat are given in the table below. Chloride fertilizer is recommended when the soil test is below 6 ppm, or 45 pounds soil chloride in the inch sample depth.
Potassium chloride (potash) and ammonium chloride are the most commonly available and widely used. Wheat's primary advantage is the established root system that can take up nitrogen in the early spring before corn is even planted," Casteel says.
While that's an advantage in the sheer volume of the nitrogen you'll likely need to apply, you'll need to make certain you're putting down the right amounts in the right spots in the field. Abstract. Stripe rust, caused by Puccinia striiformis, can be controlled by growing resistant cultivars, applying fungicides and through some cultural developing and growing resistant cultivars is the most preferred approach for control of stripe rust and a great body of knowledge has been obtained for resistance, the topic of resistance is discussed in Chap.
In winter wheat production maturity advances of 5 to 7 days have been observed. stripe rust, leaf rust, and Septoria, while in corn and grain sorghum it has been shown to suppress stalk rot. Fertilizing with chloride There are several -fertilizer sources of Cl, but the most common and readily available is.
Winter wheat fertilization recommendations in North Dakota previously were similar to spring wheat and durum. As a larger research base was developed for spring wheat and durum, separating the winter wheat from other wheat became necessary due to their unique nutrient requirements.
The effects of stripe rust on N yield are most likely associated with reduced uptake of N during grain filling. fertilizer applied to winter wheat. Both timing and amount of N were varied to. Wheat stripe rust (Puccinia striiformis f. tritici, Pst), is one of the most serious diseases of wheat (Triticum aestivum L.) gain a better understanding of the protective mechanism against stripe rust at the adult plant stage, the differences in photosystem II and antioxidant enzymatic systems between susceptible and resistant wheat in response to stripe rust disease (P.
Both phosphorus and potassium suppressed brown rust, but the effect of potassium might have been related partially to the chloride in the potassium chloride fertilizer (Sweeney et al., ). Stripe rust of wheat caused by Puccinia striiformis f. tritici reduced kernel mass and the number of kernels per head in field epidemics from to in southern New South Wales.
These epidemics began at the stem elongation stage of growth in and at booting to heading stages in the other years. The effects were greatest in very susceptible cultivars when the epidemic began before. Miller, T.; Jungman, M. Chloride fertilizer in winter wheat - effect of Cl and interactions with foliar fungicides under severe leaf rust pressure.
Proceedings of Intensive Wheat Management Conference, March 4 to 5, ; Texas Agricultural extension Service, The Texas A&M University System: College Station, TX, Among the most notable impacts of Cl- is its role in reducing the effects of numerous plant diseases.
This effect may be related to its function in osmotic regulation. In wheat, Cl- has been shown to suppress take-all root rot, tan spot, stripe rust, leaf rust, and Septoria, while in corn and grain sorghum it has been shown to suppress stalk rot. Foliar N fertilizer products are just as effective as traditional N fertilizers on a pound-for-pound basis, but they are not more effective than traditional N fertilizers.
They can be applied in a broadcast spray application at later growth stages of wheat growth than traditional N fertilizer products without damaging the wheat. Diseases continue to be important constraints in wheat and barley conservation cropping systems in the semiarid Pacific Northwest.
Several diseases are more damaging in highthan low-residue seedbeds, and in crops planted during early autumn to reduce soil erosion during winter, especially unirrigated winter wheat in rotation with summer fallow in low rainfall zones (– mm).R.F. Park, in Encyclopedia of Food Grains (Second Edition), Stripe Rust.
Stripe rust (also known as yellow rust), caused by P. striiformis f. sp. tritici (Pst), is a very destructive disease of wheat globally, having been reported from more than 60 countries and on all continents except pathogen infects leaves and leaf sheaths and can cause severe infection of glumes.Figure 1.
Statewide N-rate data and wheat yield from to Available-N includes soil test nitrate-N to 2 feet in depth, fertilizer N rate and any previous crop N credit. Wheat response to N fertilizer is closely linked to wheat protein concentration. Growers rely .
