Embodiment 1

[0013] 1. Material preparation

[0014] (1) Preparation of lime sulfur mixture stock solution

[0015] It is made by decoction of lime, sulfur powder and water. First adjust the sulphur powder to sulphur paste, pour 130 kg of water into the pot, add 20 kg of pre-adjusted sulphur paste when the water temperature rises to 40℃, and when the liquid temperature is 60℃, add quicklime along the side of the pot from all around 10kg, after the medicinal solution boils, keep it at 120°C and boil it for another 45 minutes. When the medicinal solution turns brownish-red, stop the fire and set aside.

[0016] (2) Preparation of Bordeaux mixture:

[0017] The Bordeaux mixture is prepared from 1kg of copper sulfate, 1kg of lime and 200kg of water, for use.

[0018] 2. After deciduous grape leaves and before germination in early spring, spray the lime-sulfur mixture of 6 Baume degrees twice, mainly to kill overwintering bacteria, mites, whiteflies and other pests, and spray the branches each time Ca...

Abstract

The invention relates to a method for preventing grape diseases, which comprises the following steps of: a) after grape defoliation and before early spring sprouting, spraying lime sulfur with a baume degree at 5-6 for 2 times; b) during the growth period from July to October, spraying a Bordeaux mixture (diluted for 200 times) for one time per 15-20 days, and totally spraying for 6-8 times; and c) after blooming for 10, 40 and 70 days, spraying Vitacat (diluted for 10000 times) for 3 times. According to the method provided by the invention, the lime sulfur, the Bordeaux mixture and the Vitacat are adopted during different growing periods of the grape; the technical effect is obvious; the method is simple and labor-saving, is low in cost, can effectively prevent downy mildew and powdery mildew of the grape, and plays a significant role in ensuring the production of green, organic and high-class grape.

Description

Technical field [0001] The invention belongs to the technical field of plant protection, in particular to a method for preventing grape diseases. Background technique [0002] At present, most production areas use chemical pesticides to prevent and control grapes after they become ill, which affects the appearance and quality of grapes, and pesticide residues reduce the safety of grape food. In the prevention of grape diseases, in the past, the spraying of synthetic chemical pesticides was used to prevent grape diseases. This method was used to prevent grape diseases, resulting in excessive pesticide residues in grapes, which seriously affected the health of consumers. Summary of the invention [0003] The technical problem to be solved by the present invention is to further improve the quality of grape fruit, aiming at the diseases prone to occur in grapes, and provide a grape disease prevention method suitable for grape green and organic cultivation management. [0004] The tech...
