Compound corn seed coating agent for preventing diseases and insect pests and controlling growth

Abstract

The invention discloses a compound corn seed coating agent for preventing diseases and insect pests and controlling growth. By grinding and mixing, the compound corn seed coating agent is prepared from a pesticide, a bactericide, a plant-growth regulator and trace elements as effective components, and a wetting agent, a dispersant, an emulsifier, a thickening agent, a film forming agent, an antifreezing agent, an antifoaming agent, a mildew inhibitor, a pH conditioning agent and a warning colouration agent as assistants. The compound corn seed coating agent can effectively prevent and treat diseases and insect pests and nutrient deficiency symptom of corn in a seedling stage, can promote rooting and strengthen seedlings and can shorten base internode thereby improving corn lodging resistance.

Description

technical field [0001] The invention relates to a coating agent, in particular to a coating-type treatment agent suitable for corn, which contains insecticides, fungicides, plant growth regulators, trace elements and the like as main active ingredients. Background technique [0002] Corn is one of the main food crops in my country, the main source of livestock feed, and also an important industrial raw material. Corn is vulnerable to pests and droughts and floods in the early growth stage, and lodging problems are prone to occur in the late growth stage. At present, pest control, seedling growth and lodging resistance are important means to increase maize yield. [0003] In order to solve the above problems, the traditional methods are seed soaking, seed dressing and soil disinfection. Seed soaking has the disadvantages of large dosage and serious waste; seed dressing has the disadvantage of being difficult to stir evenly and damages the seeds; soil disinfection has the di...
