Lucerne selection. The activity level of a lucerne variety determines the number of cuts or grazings across the season. High winter activity lucernes can be cut more often than more dormant types due to their more erect habit, faster regrowth and longer growing season. of infected lucerne seed or hay. PEST SIGNIFICANCE Economic impact In the USA, bacterial wilt may be considered the most important disease of lucerne, reducing hay yields and killing plants very rapidly, so that fields become unprofitable after years, particularly in well irrigated areas. In Australia, the disease is a serious problem.

Bacterial wilt of lucerne, caused by Clavibacter michiganensis subsp. insidiosus (Cmi) is an important disease of lucerne worldwide. Detection and identification of the pathogen, especially in symptomless plant material, is difficult and often requires plating on specific media. Three polymerase chain reaction (PCR)-based assays have been published for identification of Cmi.

Fast recovery after cutting makes 55V Following the 1st record of Corynebacterium insidiosum in Australia in [cf. 46, ] an extensive survey was undertaken in N.E. Victoria in areas exporting lucerne and lucerne hay to New South Wales. Seven infected stands were discovered in 4 different localities near Cobram and the identity of the pathogen confirmed.
The disease is thus centred on Cobram in the N.E. and Sale in the S.E.

FREE LUCERNE MANUAL VISIT OR CALL PIONEER TO REQUEST YOUR FREE COPY. Bacterial wilt of lucerne is caused by the bacterium Clavibacter michiganense subsp. insidiosus (Cmi). The disease causes wilting, stunting and yellowing. In the field the symptoms of the disease are not severe until the second or third year when it begins to cause significant yield loss.
Ditylenchus dipsaci transmitted Corynebaeterium insidiosum into crown buds of lucerne resulting in an increased bacterial wilt in the wilt-susceptible variety "Grimm". Observations indicate that C. insidiosum is carried on, rather than within, the nematode.
D.J.H. A trial is reported and results tabulated of the susceptibility of lucerne (varieties Buffalo and Grimm) to bacterial wilt (Corynebacterium insidiosum) at varying levels of soil N, P and K. It was concluded that both varieties were most resistant when N and P were low and K medium or high.- R.H.F.
Bacterial wilt: Resistance is desirable on some river systems only (seek local advice). Stem nematode: Resistance desirable on some river systems only (seek local advice). Potential hay quality: Highly winter active varieties may be more stalky especially as lucerne stands thin.

In this paper a full description is given of the bacterial wilt of lucerne (Medicajo saliva) caused by Apiatiobacter insidiosum [R.A.M., v, p.
36], which is stated to be a most serious and threatening disease in some of the irrigated and more humid areas of the United States. It is advised that seeds must be treated with Rhizobium Bacteria. Lucerne can produce high yields from tons of dry matter per ha per season when properly irrigated and given enough fertilizer.
It uses 21kg K, 13kg Ca, kg Mg, kg P, kg S and kg N to produce 1ton dry matter. Optimum Planting Date for Lucerne is from February to. The results of preliminary studies insome of which have been noticed from another source [see above, p.
], of the inheritance in lucerne of resistance to bacterial wilt (Phytomonas insidiosa) [Aplano-bacter insidiowm: R.A.M., xiii, p. ] indicated that resistance behaves as an intergrading character and probably depends on a complex of genetic factors, an interpretation of which is. Bacterial wilt of lucerne Fig.
I-Field symptoms of bacterial wilt of lucerne: The three plants on left show stunting. some proliferation of stems, reduction in size and distortion of leaflets, and yellowing of foliage; the plant on right shows no symptoms of infection.
All plants were close to one another in a lucerne stand at Willowby, Mid. stem nematode, Australian lucerne yellows, bacterial wilt and various leaf spots. All of these pests and diseases are listed in Tables 7 and 8. 42 Table 7. Major diseases of lucerne Symptoms Occurrence Spread Control Phytophthora root rot (Phytophthora medicaginis) –fungus.
Sincenew diseases have been found to occur here, notably bacterial wilt of lucerne, and research has provided information on the biology, ecology, incidence and importance of many of these lucerne diseases.
Over the last ten years there have been many articles on lucerne diseases. Download Citation | Detection of bacterial wilt pathogen of lucerne by PCR | A polymerase chain reaction (PCR) based assay was compared with assay involving traditional microbiological tests to.
reported in the main lucerne-producing MSs. There are no indications that in last decade the pathogen has a high impact on lucerne production in the EU, possibly because of the use of bacterial wilt-resistant varieties. C. michiganensis. subsp. insidiosus. is seed-borne and probably seed-transmitted, although with some uncertainty.Fusarium wilt, caused by several formae speciales of Fusarium oxysporum, is an important disease of most crop and pasture legumes, including field pea (Pisum sativum), chickpea (Cicer arietinum), lucerne (alfalfa, Medicago sativa) and barrel medic (M.
truncatula). Medicago truncatula is an important pasture legume and a model legume species. Hence, it can be used to increase our knowledge of.Pioneer ® Brand 54Q29 Lucerne HIGH YIELDS, FAST RECOVERY 54Q29 is a new, high yielding 4 dormant* variety (slightly more winter dormant than 55Q27) with above-average forage quality.
