Pepper rust occurs in all producing areas and is one of the major diseases of pepper. Often cause a lot of jalapeno pepper, a direct impact on the yield and quality of pepper. Therefore, prevention and control should be advanced, losses should be reduced, and yields and benefits should be increased.
The main symptoms
Pepper rust mainly damages the leaves, reduces the photosynthesis of the leaves, and reduces the accumulation of organic matter. At the early stage of disease, water-stained spots appeared on the front of the leaves and gradually expanded, showing a yellowish-brown worm-like appearance. The damaged prickly ash tree can often sprout two new leaves in a year, and the new leaves can still be susceptible.
The law of incidence
The time of onset of pepper rust varies depending on the characteristics of climate, geography, and management. According to the author's many years of investigation results, the local general from the end of June to late July, the onset of disease, generally from early August to early September, the incidence of disease from September to late September is the peak period, a large number of victims of loss of leaves. Excessive management, severe soil consolidation, severe grass shortage, unpleasant vegetation, and debilitating prickly pepper trees have a serious onset.
Prevention
1. Strengthen management and improve tree resistance. One is cultivating and weeding. Due to the shallow root system of prickly ash, timely cultivating and loosing weeds can improve soil physical and chemical properties, reduce nutrient ineffective consumption, promote healthy growth of trees, and enhance disease resistance; Second, top-dressing replenishment should be based on The tree grows and fertilizes in the spring, late-to-mid-late growth period from late June to early July and after pepper harvesting, supplementing nutrition. According to climate conditions, in the event of drought, it is necessary to combine fertilization with supplementary irrigation. To prevent water and fertilizer deficiency and weaken the tree vigor and reduce the resistance to disease; Third, appropriate pruning, pull branches, reduce the field closed, improve plant ventilation and light conditions, promote tree growth and growth, and enhance disease resistance.
2, late autumn garden, reducing the source of overwhelming bacteria. In late autumn, after the defoliation of prickly ash, it is necessary to cut off the dead branches, branches of diseases and insects, and the residual diseased leaves in time, clean the fallen leaves under the trees in the garden, eradicate the weeds in the garden and around, and bring them out of the park for centralized treatment, so as to reduce the source of the winter fungus and reduce the disease. Incidence.
3, chemical control, control the spread of the disease. Before the onset of the disease spray 1:1:100 Bordeaux spray protection, spray again every 10-15 days. The diseased prickly ash tree can be sprayed with 65% mancozeb WP 400-500 times or 1:2:200 times Bordeaux liquefaction at the beginning of the disease. It is sprayed once every 10 days and sprayed 2-3 times.
