What pesticide does soybean root rot use?

Soybean, also known as soybean and soybean, is one of the important food crops in China, which is cultivated all over the country and widely cultivated all over the world. What kind of pesticide is used in soybean root rot? What are the symptoms?

What pesticides are used for soybean root rot?

Soybean root rot was sprayed with 1500 times of 50% Anke wettable powder and 25% metalaxyl wettable powder. It can also be irrigated and applied with 1000 times of 10% Shuangxiaoling water agent, 2000 times of 70% carbendazim wettable powder, 1000 times of carbendazim wettable powder and 20% of Longke fungus suspension.

Second, what are the symptoms of soybean root rot?

Soybean root rot mainly occurs in soybean roots, seedlings or adults. However, the performance was slightly different in different periods. At the initial stage, irregular reddish brown spots appeared at the base of the stem or radicle epidermis, then became reddish brown sunken necrotic spots, spread around the rhizome and withered the root bark, and the roots of the injured plants were underdeveloped. the root nodule is few, the aboveground is short and thin, the leaf color is light green, and the branching and podding are obviously reduced.

Third, how to prevent soybean root rot?

1. Persist in rotation with Gramineae crops for more than three years, strictly prohibit soybean continuous cropping, choose the tillage method of ridge cultivation, which will help to reduce soil moisture and increase temperature, thus reduce the disease; choose timely late sowing, and start sowing when the soil temperature stably passes 8 ℃-9 ℃, and require its depth not to exceed 5 cm. Sufficient basal fertilizer, seed fertilizer and topdressing fertilizer should be applied in time, and multi-component compound liquid fertilizer should be selected for foliar fertilization, which can make up for the deficiency of fertilizer and water absorbed by root diseases, and ploughing and soil cultivation should be carried out in time to promote the formation and restoration of new roots at the base of aboveground stem.

two。 The stagnant water in the field should be removed in time after rain in order to reduce the soil moisture. When ploughing is carried out in time, the land should be carefully ploughed and leveled to improve the aeration condition of the soil. Increase the application of organic fertilizer, cultivate strong seedlings, enhance disease resistance and control underground pests. In the case of low temperature in spring, the land with heavy soil viscosity is the frequent occurrence area of root rot, so the tillage level should be further improved, which is also an important disease prevention measure.

Therefore, it is necessary to take preventive measures to prevent the occurrence of soybean root rot, and the majority of growers should pay attention to it.
