The latest control methods of blueberry fruit

Blueberry has high nutritional value and is very popular with consumers in the market, but one of the most serious diseases occurs when planting ossified fruit, which will seriously affect the yield of blueberry and cause great economic losses to farmers. So what is the reason for blueberry nuts? How to prevent and cure it? Let's take a look at the detailed introduction.

1. Symptoms of stiff fruit

Stiff fruit is a disease caused by fungi. in the early stage of the disease, mature spores germinate on the surface of new leaves or flowers, and hyphae develop on the surface of flowers and leaves, resulting in cell rupture and death, resulting in sudden withering and browning of leaves, buds, flowers and other parts. After about a period of time, fungal spores will produce powdered matter to cover leaves, stems and styles, and at the same time spread like blooming flowers for secondary transmission, resulting in fruit wilting, dehydration, drying, and rigidity.

2. The regularity of the disease

After overwintering, if the fallen fruit is not cleaned up in time, its spores will germinate again, causing cyclic damage in the second year. The occurrence of stiff fruit disease is related to climate and species. It is serious in rainy and high temperature areas in early spring and in areas with long low temperature in winter. The disease degree of different varieties will be different, some varieties have weak disease resistance and are easily infected at the time of disease, while some varieties have strong disease resistance and are not easy to catch the disease.

3. Prevention and control methods

First of all, we should choose varieties with strong disease resistance to plant, reduce the probability of infection, clear the garden before overwintering, burn or bury the fallen leaves and fruits in the orchard, reduce the pathogen and reduce the possibility of disease. Shallow ploughing and fertilizer application before flowering in spring can reduce the occurrence of diseases. When the disease occurs, the diseased leaves or flowers should be removed in time to prevent the disease from spreading. At the same time, it can also be sprayed to prevent it. Spraying urea solution in early spring will reduce the incidence of disease. Spraying azinamide before flowering can avoid plant invasion, and the effective rate is more than 90%.
