Xanthomonas fragaria is an exotic bacterial pathogen of strawberry. The pest poses a significant production threat to the strawberry market. Angular leaf spot (ALS) disease primarily destroys the leaves of strawberry plants and on occasions, also affects the plant’s flowers. It does not affect the fruit grown on infected plants, but has the potential to significantly reduce the performance and yield capacity of an infected strawberry crop.
Overview
| Symptoms |
Early symptoms of angular leaf spot form on the underside of leaves as small, angular, water-soaked spots that enlarge and become visible on the upper surface of the leaf. Daylight can usually be seen through the angular spots on the leaf. As the infection advances, reddish brown spots, 1 – 4 mm across, will develop on the upper leave surface, causing the death of tissue. Where spots are close together, they may join to form large areas of dead leaf tissue, giving the plant a blotchy appearance. If left unchecked, tissue damage may become so severe as to kill the plant. |

| What do you do if you find symptoms | Report any possible infections immediately to Biosecurity Queensland on 13 25 53. |
| Susceptible plans (hosts) | ALS is a host specific disease. The only known susceptible host of angular leaf spot is strawberry plants. |
| Infection and spread | The disease is favoured by prolonged leaf wetness caused by frequent rain, overhead irrigation, or heavy dews. ALS is readily distributed through infected nursery stock or other infected plant material. Local spread of the bacteria is by water splash and wind dispersal. |
| Where angular leaf spot occurs | The infection attacks the leaves of strawberry plants. In some cases, the bacterium has also been known to infect strawberry flowers, but does not directly affect fruit. |
| Significance | ALS presents a significant risk to the Queensland strawberry industry. Although this pathogen does not directly infect the fruit, infection generally causes stress to the plant and the quality of fruit is significantly reduced. |
| Human health | ALS does not affect human health. |

ORGANİC FERTILIZERS AND PRODUCTIONS
LIQUID OR SOLID ORGANIC FERTILIZER PRODUCTION is not very complicated. For the production, there is need usable and tried a formulation, raw materials and mixing tank. For raw materials to be used, quantities to be used and ingredients usage rankings, you should look into this formulation. Therefore, formulation and productıon methods of ORGANIC FERTILIZERS are important. If you have not a good formulation, you cannot make healthy and efficient production of any fertilizer.
If you need any manufacturing formulations and production methods about
any liquid and solid organic fertilizer,
ORGANIC

is enough.
This encyclopedia has many formulations about organic soil conditioner,humic acid productions,compositions,fulvic acid manufacturing,organic fertilizers,animal manure,amino acid organic fertilizers, organomineral powder fertilizers,organomineral liquid fertilizers productions,liquid root growth fertilizers formulas,granular root growth fertilizers,seaweed organic fertilizers,wermicompost fertilizers formulations,gel organic fertilizers,organomineral gel fertilizers manufacturing and any organic fertilizers etc.
All organic fertilizers in the encyclopedia are producible easily.You need no help and no technıcal support. The encyclopedia is enough to produce organic fertilizers itself.
