Problems solved by technology

However, at present, due to the weak research foundation of sesame diseases, the progress of sesame disease-resistant breeding is relatively slow, and the overall disease resistance of varieties still needs to be improved; in actual production, farmers mainly use chemical control methods for sesame diseases, and the control methods are relatively single
In the actual application of chemical control and biological control technologies to prevent and control sesame wilt, there are still problems such as poor control effect and high cost
In addition, in the process of disease prevention and control, the frequent use of a large number of chemical pesticides can easily lead to gene mutations and antagonistic effects of pathogenic bacteria, and damage the ecological environment, and frequent problems such as excessive pesticide residues in agricultural products

Embodiment 1

[0026] Example 1: A method for efficient comprehensive prevention and control of sesame diseases in Huanghuai sesame production areas

[0027] (1) Select 5 mu of farmland with better drainage and irrigation conditions in Xiangcheng, Henan, and plant Zhengzhi 13, a high-resistance fine variety suitable for the ecological conditions of the Huanghuai region. Wheat stubble is planted with equal row spacing, the row spacing is 40 cm, and 10,000 plants / mu.

[0028] (2) Before sowing, use 0.15% of seed weight as 25 g / liter Shileh for seed dressing before sowing, and then sow after drying.

[0029](3) Prevention and control of diseases at the seedling stage: for strong seedlings, 0.01% brassinolide 3000 times (10 ml / mu) + NEB 2500 times (10 ml / mu) + biocontrol bacteria (Bacillus licheniformis + subtilis) are selected per mu Bacillus) bacteria solution 600 times (50 ml / mu), spray after mixing.

[0030] (4) Prevention and control of diseases in flowering stage: Sesame enters flowering...

Embodiment 2

[0033] Example 2: A method for efficient and comprehensive prevention and control of sesame diseases in North China sesame producing areas

[0034] (1) In Jingxian County, Hebei Province, 15 mu of farmland with better drainage and irrigation conditions were selected, and Jihangzhi No. 1, a high-resistance fine variety suitable for the ecological conditions of North China, was planted. Corn stubble is sown and planted in double rows with a ridge width of 60 cm and a ridge height of 10-12 cm. The average row spacing is 55 cm, 10,000 plants / mu.

[0035] (2) Dress the seeds with 0.15% of the seed weight of 25 g / L Shileh before sowing, and sow after drying.

[0036] (3) Disease prevention and control at the seedling stage: 2 pairs of true leaves after the emergence of sesame seedlings, there are a small number of wilted diseased plants. Select 0.01% brassinolide 3000 times (10 ml / mu) + NEB2500 times (10 ml / mu) + Bacillus subtilis bacterial liquid 600 times (50 ml / mu), mix and spr...

Abstract

A high-efficiency comprehensive method for preventing and controlling sesame diseases, comprising the following steps: (1) selecting disease-resistant varieties; (2) selecting superior farmland; (3) timely sowing, reasonable dense planting, and crop rotation; (4) seed packaging (5) prevention and control of diseases at the seedling stage; (6) prevention and control of diseases at the flowering stage; (7) timely harvesting. The invention can effectively prevent and control major diseases such as sesame blight, stem point blight and leaf blight, the comprehensive prevention and control effect can reach 77.37%-89.5%, and the yield can be increased by 85.9%-93.6%. The present invention has simple comprehensive prevention and control steps, reasonable design, high efficiency and safety, strong implementability, high prevention and control efficiency, good repeatability of results, and low cost. The technology has a wide range of applications, and the economic and ecological benefits are remarkable.

Description

technical field [0001] The invention relates to a method for preventing and controlling sesame diseases, in particular to an efficient and comprehensive method for preventing and controlling sesame diseases. Background technique [0002] Sesame (Sesamumindicum L., 2n=26), belonging to the genus Linaceae, is an annual herb. It is one of the oldest oil crops in the world, and it is also a high-quality oil crop sesame in my country. The annual planting area of ​​sesame in my country is about 12 million mu, and the total output is about 750,000 tons, which plays an important role in the international oil trade. [0003] Sesame planting areas in my country are very extensive, with Henan, Anhui, and Hubei as the main producing areas, followed by Jiangxi, Shaanxi, Hebei, Shanxi, Jiangsu, and Liaoning. The growth period of sesame is short (about 85 days), but due to the poor disease resistance of sesame, major diseases such as sesame blight, stem blight and leaf blight are more com...
