Description
Technical field
The present invention relates to agriculture field, particularly, relate to a kind of disease resistance composition, and the purposes of this disease resistance composition.
Background technology
Bacterial wilt of tomato is one of bacterial disease common on tomato, and various places generally distribute, and protection ground and open country all can occur, and the southern and rainy time occurs serious.Fall ill and cause blue or green withered the dying of plant when serious, cause Severe Reduction even to have no harvest.The control for this disease in the urgent need to efficient germicide in production.This disease is infected and is caused by bacterium Pseudomonas solanacearum (Pseudomanas solanacearum Smith).The various crop such as harm tomato, eggplant, capsicum, potato and ginger.Pathogenetic bacteria mainly survives the winter on field or potato ball with invalid body, and during without host, germ can reach 14 months in Tu Zhongying saprogenesis, becomes the main primary source of infection of this disease.This bacterium is mainly propagated by rainwater, irrigation water and farm implements, and sick potato piece and the fertilizer that carries disease germs also can carry disease germs.Germ is invaded from root or basal part of stem wound, and expansion in the vascular bundle tissue in plant body causes conduit to stop up and cytotoxic.
Tomato wilt claims again wilt disease, and majority occurred in the tomato phase of yielding positive results, and part is injured, and complete stool is aobvious sick.Their early stage, only plant lower blade flavescence, but majority do not come off, along with the development of the state of an illness, the flavescence from bottom to top of sick leaf, browning, except top several pieces intact, all the other are all downright bad or shrivelled.Sometimes diseased plant one lateral lobe sheet withers vertically, and opposite side blade is still normal.This disease is caused by Deuteromycotina fungi-tomato point Fusariumsp tomato specialized form (Fusarium oxysporum f.sp.Lycopersici Snyder et Hansen), main harm rhizome portion, and main manifestations is the strain phase.The morbidity of strain phase is initial, and blade is wilted sagging at noon, and has and upper flavescence, and then browning withers vertical, sooner or later recover again normal, leaf look thin out, and like lack of water shape, the state of an illness develops from bottom to top, repeatedly after a couple of days, spread all over gradually whole strain blade and wilt saggingly, blade no longer restores, and last complete stool is withered.Cross-sectional sick stem, sick portion vascular bundle is brown.When humidity is high, the mould layer of the normal cloth pink of the basal part of stem of dead strain, the i.e. conidiophore of germ and conidium.
At present the means of prevention of above-mentioned plant disease is comprised: use withered pair of wetting powder of enemy, antibiotic in pyrimidine nucleoside class, agricultural streptomycin sulphate or new phytomycin spray or fill with root.But there is the poor defect of preventive effect in current means of prevention.
Summary of the invention
The object of the invention is to overcome the lower defect of preventive effect that agricultural chemicals exists in the time of the disease of control crops, the disease resistance composition that a kind of usefulness is higher is provided.
To achieve these goals, the invention provides a kind of disease resistance composition; This disease resistance composition contains Zhongshengmycin and amino-oligosaccharide; With respect to the Zhongshengmycin of 1 weight portion, the content of amino-oligosaccharide is 0.1-80 weight portion.
The present invention also provides the purposes of disease resistance composition as above in the disease of control crops.
By technique scheme, Zhongshengmycin and amino-oligosaccharide in disease resistance composition of the present invention can be obtained the effect of notable synergistic, thereby have improved the usefulness of the disease of anti-crops.
Other features and advantages of the present invention are described in detail the embodiment part subsequently.
