Description
Technical field
The invention belongs to crop disease control field, relate to a kind of compositions preventing and treating galic bolt maculopathy and application thereof.
Background technology
Galic bolt is the tender scape of children of Bulbus Allii, nutritious, and function highlights, and is deeply liked by consumer.Galic bolt can by the measure such as low temperature, controlled atmosphere carry out batch, Long-term Storage and realize year-round supply.But galic bolt can be threatened by various diseases before and after gathering, the Major Diseases before wherein adopting is galic bolt maculopathy.
Galic bolt maculopathy refers to the yellow scab occurred on a kind of sedge stem and a kind of sedge bud of galic bolt, and the initial stage is Semen Sesami size, scatterplot shape, can connect in flakes time serious.With the galic bolt of maculopathy after Storage in cold bank 3～4 months, concave downward at macula lutea, it is highly prone to microbial infection and aging, contracting root, rotten nest etc. occur.Suffering from the galic bolt not storage tolerance of maculopathy, purchase and selling price are the most relatively low, and the time that disease incidence is high has a strong impact on galic bolt quality, affects the income of peasant.Fourth surpass the article delivered on " the Changjiang river vegetable " for 2003 analyzes the whole nation galic bolt production and marketing market, it is indicated that the diseases such as galic bolt maculopathy the most seriously restrict Bulbus Allii and galic bolt quality, even cause the minimizing in planting garlic region time serious.
Following 2 kinds of viewpoints are had for the pathogenic factor of galic bolt maculopathy:
A kind of viewpoint thinks that galic bolt maculopathy is a kind of microorganism disease, field carry disease germs and cause, and available antibacterial is prevented and treated.The article that Shen Rui 2007 delivers in " Henan science and technology " is pointed out with 1000 times of liquid of 50% Sukeling agent in 4～May or spray with 800 times of liquid of 40% thiophanate methyl and can suppress the generation of galic bolt maculopathy, more preferable with 0.3% potassium dihydrogen phosphate mixing spraying effect.But use chemical bactericide to be easily caused pesticide residues exceed standard and induce pest and disease damage resistance, and, chemical bactericide residue problem has become as the key factor affecting China's fruit and vegerable outlet.
The second viewpoint thinks that galic bolt maculopathy belongs to physiological disease, is susceptible under adverse environmental factor, and its morbidity has obvious relation with planting technology, field fertilization management.Zhou Xiaolin introduces in the master thesis of 2012, and galic bolt maculopathy belongs to physiological disturbance, can increase the weight of the generation of disease such as wet weather, greasy weather before gathering, and needs by changing planting system, improving field management, change the measures such as kind disease is mitigated or eliminated.During implementing, certain difficulty is there is at present by measures such as change planting system, improvement field management.Xue Pingxia in the article delivered for 1997 with experiment prove galic bolt maculopathy disease sites cultivate after microscopy do not find any pathogen, and point out that application of potash fertilizer has certain inhibitory action to this disease.But the improvement of galic bolt field management and planting system etc. is required to take time and effort, application of potash fertilizer is the most undesirable to the effect of preventing and treating galic bolt maculopathy.
The most less for the research of galic bolt maculopathy.And for scab evil, basic employing uses chemical bactericide or the method spraying antagonistic microbe.But use the safety problems such as the chemical residual that chemical bactericide easily causes.Antagonistic microbe uses has certain condition restriction and effect limited.Therefore, it is badly in need of developing a kind of specificity safely and efficiently medicament for galic bolt maculopathy, to reduce the generation of galic bolt maculopathy, alleviates the loss in galic bolt storage.
