There is a unique way to prevent grape downy mildew. Microbial agents are very effective.

Grape downy mildew is one of the main diseases of grape, which is distributed in vineyards all over China, especially in wet and rainy areas, the disease is more serious, which will lead to scorched leaves, poor growth of new shoots, and even young fruit rot, seriously affecting grape quality and yield. it will also lead to poor cold resistance of grapes, causing difficulties for overwintering.

Until the outbreak of grape downy mildew to control, is bound to greatly increase the cost, the later quality, output will also have an irreparable impact, so grape downy mildew, prevention is the key! So what aspects should we start with?

Clear Garden Prevention:

Thoroughly clean the vineyard in autumn, especially for the orchards with downy mildew in that year, thoroughly clean, cut off the disease, collect diseased leaves, and concentrate on burning.

Pharmaceutical prophylaxis:

After clearing the garden, the microbial agent was applied near the grape plant, and then added once a month to achieve the preventive effect.

After the active beneficial bacteria in the microbial agent enter the soil, they can inhibit or kill the pathogenic bacteria through their own life activities, improve the soil structure, fertilize the soil, make the grape root system developed, the stems and leaves strong and thick, and improve its disease resistance. resist the infection of grape downy mildew from the root.

Strengthen orchard management:

After the application of microbial agents to establish a protective barrier, it is still necessary to strengthen orchard management, so that the vineyard planting environment is not conducive to disease breeding, and appropriate supplement of nutrients needed for growth, so as to make grape growth stronger and better quality!

First, it is timely to carry out summer clipping to bind the branches and improve the ventilation and light transmission conditions of the grape shelf surface.

Second, weeding in time, pay attention to drainage after rain, and reduce ground humidity.

The third is to increase the application of phosphorus and potassium fertilizer to improve plant disease resistance and fruit quality.
