Embodiment 1

[0020] A method for preventing and controlling root diseases of crops that can be used in wheat corn rotation as straw returning to the field, comprising the following steps:

[0021] (1) No-till sowing of corn after wheat harvest

[0022] After the wheat is harvested, the stalks are covered on the soil surface, and the soil is loosened with a corn no-tillage seeding and fertilizing machine, and the corn is sown; the corn is treated with a suspended seed coating agent;

[0023] (2) No-till sowing of wheat after corn harvest

[0024] After the corn is harvested, the corn stalks are chopped and evenly covered on the soil surface, and the soil is deeply loosened by a wheat no-tillage seeding and fertilizing machine, and the wheat is sown; the wheat is treated with a suspended seed coating agent;

[0025] The active ingredients in the suspension seed coating agent are fenthiastrobin and fludioxonil, and the weight percentage of the active ingredients is 50% of fenthiastrobin and ...

Embodiment 2

[0027] A method for preventing and controlling root diseases of crops that can be used in wheat corn rotation as straw returning to the field, comprising the following steps:

Abstract

The invention provides a prevention and treatment method for crop root diseases during returning to field of wheat and corn crop rotation straw. A flowable concentrate of seed coating is adopted for processing corn or wheat seeds and can be used for preventing and treating the root rot.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for preventing and treating root diseases of crops in wheat moons used as straw returning to the field. Background technique [0002] Root rot of wheat caused by soil pathogens such as Helminthes rot, A. graminearum, Fusarium, Rhizoctonia and other soil pathogens alone or in combination is collectively referred to as wheat root rot. It generally occurs in wheat areas such as North China, Northwest China and Northwest China, and wheat can be infected with this in all growth stages. At present, in the main wheat planting areas in my country, a planting mode of wheat and corn has been formed. Some wheat root rot pathogens are also pathogenic bacteria of corn. This mode will cause the accumulation of pathogenic bacteria in the field and aggravate the disease. occur. [0003] With the gradual deepening of people's understanding of wheat root rot, more and more attentio...
