Control of soybean root rot
1. Disease resistant varieties were selected. two。 Rotation with corn, millet, sweet potato and other non-host crops. 3. Increase the application of farm manure, potash fertilizer, phosphate fertilizer and so on when sowing. 4. When sowing, metalaxyl granules were applied to absorb soybean roots and prevent root infection. 5. Mix seeds with 35% metalaxyl powder with 0.3% seed weight before sowing. 6. Strengthen field management, timely deep ploughing and mid-ploughing soil weeding, timely removal of stagnant water after rain to prevent excessive humidity. 7. When diseased plants are found, the remains of diseased plants should be removed thoroughly, and planting holes in diseased plants and

Occurrence and Control of Cotton Root Rot in Northern Xinjiang
In 2007, northern Xinjiang suffered varying degrees of cooling and rainfall in April, May and August, respectively. Cotton root rot occurred seriously, and the incidence of cotton fields reached 20% to 50%, which had a certain impact on cotton production in northern Xinjiang. First, the symptom pathogen overwintered with chlamydospores on the plant remains in the soil, and germinated and infected the following year. After the cotton was infected, the leaves shrunk or wilted, and soon fell down and died. The base and root of the diseased seedling were purple-brown, gradually rotted, the cortex was dry-rotten, pulled out from the soil, and the root was rotten brown.

High-yielding cultivation techniques of black sesame
There are many varieties of black sesame, Zhongzhi 9, bred by Oil Crops Research Institute of Chinese Academy of Agricultural Sciences, is the first variety. This variety belongs to branch type, yield per mu can reach 58.33 kg. The summer sowing period is 95 days. Seed coat black, 1000-grain weight 2.63 g. The oil content is 47.3% and the protein content is more than 21%. This variety has strong resistance to stem blight and is worth popularizing. At present, sesame is mainly planted by "double-stem cultivation method". The method mainly removes the apex when the third pair of true leaves of sesame seedlings are half unfolded, so that the first (or second) pair of true leaves are axils.

A new product of black sesame is bred in Hebei.
A few days ago, Hebei Grain and Oil crop Research Institute successfully cultivated a new black sesame variety with the highest oil content in China, "Ji Heizhi No. 1, a dual-use type of oil and food", which passed the provincial appraisal. This variety integrates high quality, high yield and disease resistance, and solves the contradiction between high yield and high quality, high yield and disease resistance of black sesame.

Hangzhi No.1 (Sesame)
Sesame is one of the main oil crops in China and a traditional characteristic agricultural product. in recent years, the planting area of sesame is 1300-15 million mu, and the total output is about 1 million tons. Henan, Anhui, Hubei and Jiangxi are the main sesame producing provinces, accounting for more than 60% of the total area of the country. Jiangsu, Hebei, Shaanxi, Shanxi and other provinces also have a certain area and a wide distribution area. There are two inter-provincial concentrated producing areas of sesame: one is in northwest Hubei and southwest Henan.

Hangzhi 1, the only new sesame variety bred by aviation technology in China.
The variety source "Hangzhi 1" is supported by the key project of "Ninth five-year Plan crop Aerospace Technology breeding" of the Ministry of Agriculture. In 1996, the parent sesame seed was provided by the Oil crop Research Institute of the Chinese Academy of Agricultural Sciences, carrying the 17th recoverable satellite launched by China, and returned to the ground after staying in space for 15 days. Ground selection has been carried out for many years since 1997. Through the comparative tests of genetic stability, yield, quality and resistance, it was obviously better than the control, and was promoted into the national sesame from 2001 to 2002.

High temperature and humidity to prevent Sesame Diseases
Recently, some farmers reported that some sesame leaves curled up and wilted, some reflected that sesame leaves wilted sharply from the top down, and some sesame leaves withered from the bottom up. What diseases are they? Farmers are also confused and have asked agricultural technicians to give technical guidance on how to prevent and control these diseases. Judging from the current climatic factors, high temperature accompanied by humidity is easy to induce sesame disease, especially in sesame land with poor drainage, low terrain or continuous cropping. Sesame disease reflected from farmers all over the country
