Southern anthracnose or crown rot, caused by Colletotrichum trifolii (Bain et Essary), is a disease which has been detected on alfalfa in the 9th decade of last century in Serbia. ALFALFA VARIETY PLACEMENT The map on page 69 can be used to determine which alfalfa varieties are recommended for your area’s climate challenges. Also, use the chart below to place the correct variety to help manage common diseases and pests in your area, and to match quality to your desired cutting frequency. To view more.
Disease Resistance Alfalfa root and crown diseases occur in most Minnesota soils. The most important diseases are Bacterial wilt, Phytophthora root rot, Fusarium wilt, Anthracnose, Verticillium wilt and Aphanomyces root rot (races 1 and 2). Variety resistance ratings for each dis-ease are available on the web at www. Head Office P.O. St. Norbert Postal Stn. Winnipeg, Manitoba R3V 1L5 Canada.

The series concludes this month.

Plant Disease Cited by: 4. Leaf diseases of alfalfa tend to become more severe after flowering begins, so harvesting at no later than 10 percent flower, or earlier, is a good cultural practice to minimize leaf disease losses.
Seeding alfalfa with a companion, or “nurse,” crop can also increase the incidence of leaf and stem diseases. Alfalfa varieties are screened. The present disclosure provides alfalfa plants exhibiting broad spectrum resistance to Race 1, Race 2, and Race 5 anthracnose.
Such plants may comprise novel introgressed genomic regions associated with disease resistance from Race 1, Race 2, and Race 5 anthracnose. In certain aspects, compositions, including novel polymorphic markers and methods for producing, breeding, identifying.
Alfalfa requires a well-drained soil for optimum production. Wet soils create conditions suitable for diseases that may kill seedlings, reduce forage yield, and kill established plants.
You can reduce some disease problems associ-ated with poor drainage by selecting varieties with high levels of resistance and by using fungicides for establish.
Fungicide seed treatments are not effective against Aphanomyces root rot. It is best managed by using resistant varieties.
Race 2 is more virulent. Many alfalfa varieties are resistant to race 1, but few are resistant to race 2. Anthracnose Definition: a serious stem and crown rot disease, which can kill individual plants and cause rapid stand.

Churchill Street, #1 | St. Paul, MN | Phone: | Fax: However, creeping bentgrass varieties vary tremendously in their susceptibility to anthracnose as well.
Older varieties, such as Penncross, Pennlinks, Dominant, Dominant Plus, L, and Crenshaw are susceptible to anthracnose, whereas the disease is rarely observed on modern varieties such as the Penn A and G series. varieties used in the West have ratings of 5, 6, or 7.
Non-hardy alfalfa varieties are usually not well adapted for Michigan, even for short-term stands. Important Diseases in Michigan An alfalfa variety consists of a population of plants, which are genetically different from each other.
Sorghum Anthracnose, caused by Colletotrichum sublineolum, is one of the most important disease causing significant economic loss of sorghum production in pathogen C. sublineolum is a highly variable pathogen.
So there is an imperative need for screening resistance sources for breeding and resistant varieties deployment. Alfalfa plants produce flowers on racemes (flower stalks) and each raceme possesses 10–35 densely packed purple flowers.
Alfalfa produces spirally coiled seed pods each containing 2–6 seeds. Pods may have a smooth or hairy outer surface. Alfalfa plants can reach a height of cm (47 in) and live for between 3 and 8 years.
Legacy Seeds is excited about alfalfa. Our alfalfa breeding program began in and has since introduced many excellent varieties, including L APH2, L HD and multiple private-label varieties that perform exceptionally well on the farm and in university yield trials.
Comments on the Disease. Anthracnose is a common problem in older alfalfa stands. The fungus persists in alfalfa debris and crowns. The disease reaches maximum severity during late summer and early fall coincident with warm and humid weather.
During the growing season, spores on stem lesions are a source of inoculum. Plant resistant cultivars with an R (resistant) or HR (highly resistant) rating to anthracnose.

Vincelli, Extension Plant Pathology, University of Kentucky. Diseases. Resistance to disease is of much greater importance when lucerne is grown under irrigation than when grown dryland.
Phytophthora root rot: Resistance is essential under irrigation and desirable on poorly drained soil types dryland. Anthracnose: Desirable to have at least moderate resistance under irrigation and in humid environments.
Information on variety, disease, and insect resistance and performance in Nebraska is available in Extension Circular EC, Selecting Alfalfa Varieties for Nebraska Cleaning debris from haying machinery before the first cutting in spring and during the growing season can help to prevent introduction of the anthracnose fungus into clean.
Anthracnose occurs sporadically throughout soybean fields in NY, though rarely reaches epidemic proportions. The disease is more prevalent during warm, humid conditions. Infection may occur at any growth stage, but symptoms usually develop during the reproductive stages. Symptoms may include small lesions on leaves, petioles and stems.

Algonquin is a very winter hardy alfalfa with a wide crown producing many fine leafy stems.istration and alfalfa production has not been conducive to the use of pesticides for disease control in alfalfa, with the exception of seed treatments.
