Embodiment 1

[0044] The present embodiment provides a kind of comprehensive prevention and control method of lentil sclerotinia, comprising the following steps:

[0045] 1) Agricultural control:

[0046] ① For the fields where the disease occurred in 2015, the infected straw and stubble were composted and fermented to eliminate the intermediate host of Sclerotinia lentils.

[0047] ② Rice was planted in 2016, corn was planted in 2017, and the fields were rotated

[0048] ③Keep reasonable row and plant spacing when planting, pruning frequently, and maintaining ventilation.

[0049] 2) Biological control:

[0050] ① Soil treatment: one week before sowing lentils, apply 60g of shell mold wettable powder per mu, dissolve in 20L of water, spray on the soil surface, turn it and mix it into the soil surface.

[0051] ②Prevention at the seedling stage, one week after the emergence of the seedlings, spray the shell mold once again.

[0052] 3) Chemical control:

[0053] Spray sclerotia net at th...

Embodiment 2

[0058] A comprehensive control method for sclerotinia sclerotiorum, comprising the following steps:

[0059] 1) Agricultural control:

[0060] ① In 2015, in the plots where Sclerotinia sclerotiorum was more severe, rice was planted for two years, and the fields were soaked in water in winter.

[0061] ② When planting lentils, plant them properly and sparsely, keep a reasonable row and plant spacing, trim once every two weeks, and keep ventilation.

[0062] 2) Biological control:

[0063] ① When planting lentils, apply 70g of shell mold wettable powder per mu, dissolve in 15L of water, spray on the soil surface, combine with plowing and mix into the soil surface 5-10 cm.

[0064] ② One week after the emergence of the seedlings, spray the seedlings and the surface soil near the surrounding area with Mushroom once.

[0065] 3) Chemical control:

[0066] At the initial flowering stage, spray evenly with 1000 times liquid of wettable powder containing 40% of sclerotia per mu, a...

Abstract

The invention discloses a comprehensive prevention and control method for hyacinth dolichos sclerotinia rot, and relates to the technical field of plant protection. The method comprises agricultural prevention and control, namely field sanitation keeping, crop rotation or fallow, moisture adjustment and row spacing and plant spacing keeping; biological prevention and control, namely soil treatment, seedling stage prevention and full-bloom stage prevention and control; chemical prevention and control, namely chemical prevention and control in an initial flowering stage and a full-bloom stage; and weather prediction, namely, preventing and controlling by using chemical medicine in advance. The method for comprehensively preventing and treating hyacinth dolichos sclerotinia rot has the advantages that early prevention and control and early drug use can be achieved, serious loss caused to production is avoided, the prevention and control effect is good, and environmental pollution is small.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a method for preventing and treating lentil sclerotinia. Background technique [0002] Sclerotinia sclerotiorum is a major disease that harms lentils, such as Dutch yellow lentils, the disease rate is as high as 36.8%, and severe plants wither and die. If it is not checked and prevented in time, it will have a great impact on the later yield loss of lentils. Affected plants often begin to infeste the vines near the base of the ground or on the first branches. It was water-stained at first, and gradually turned grayish white, and the cortical tissue was torn and dried up, showing a fibrous shape. When wet, black sclerotia can be seen in the middle cavity of the stem diseased tissue, which looks like rat droppings. In severe cases, a white flocculent mold layer can be densely grown on the surface of the diseased stem and leaves, and black sclerotia can form on it, and s...
