Abstract

The invention relates to a disease prevention and control method for tomato seedlings. According to the technical scheme, the method includes the steps of firstly, processing seeds before sowing; secondly, sterilizing substrates; thirdly, using the 600-800 times solution of a 72.2% propamocarb hydrochloride aqueous solution to spray the seedlings when the cotyledons of the seedlings flatly spread; fourthly, after the true leaves of the seedlings grow and after seedling bed water spraying, mixing the 550-650 times solution of 75% chlorothalonil wettable powder with the 3000 times solution of organic silicon auxiliaries, and using the mixture to perform foliar spraying; fifthly, one day later, after the seedling bed water spraying, mixing the 1200-1700 times solution of 46% copper hydroxide water dispersible granules with the 3000 times solution of organic silicon auxiliaries, and using the mixture to perform foliar spraying. The method has the advantages that the cultivated tomato seedlings are healthy, free of diseases and stable in quality, and the method is simple to operate, low in cost and widely applicable to the technical field of tomato seedling cultivation.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for preventing and controlling tomato seedling diseases. Background technique [0002] Vegetables are the necessities of people's life. Vegetable seedlings are a vital link in the development of the vegetable industry. Healthy seedlings are the basis for ensuring a good harvest in the future. Vegetable tray intensive substrate seedling cultivation technology is to make full use of natural resources under artificially controlled environmental conditions, adopt scientific and standardized technical measures, and use mechanized and automated means to make seedlings intensively produced to achieve rapid, high-quality, and high-efficiency. It is a modern seedling raising method for batches and stable seedling growth, which has been popularized in a large area in production. [0003] The most basic work of vegetable intensive seedling cultivation is to reduce the probab...
