Embodiment 1

[0020] The invention provides a method for preventing and controlling fresh corn rust by using a photosynthetic high-fat film agent, which comprises a photosynthetic high-fat film agent, and the photosynthetic high-fat film agent is composed of the following components by weight ratio: 300 parts of dodecyl alcohol, an emulsifier 8 parts, 5 parts of co-emulsifier, 40 parts of thickener, and 800 parts of water, after the photosynthetic high-fat film agent is diluted with water, the corn is sprayed.

[0021] Further, the photosynthetic high-fat film agent comprises the following steps to corn spraying:

[0022] A1: At the seedling stage, dilute the photosynthetic high-fat film agent with water 250 times, and spray the corn once every 14 days; at the same time, appropriately increase the base fertilizer and organic fertilizer. It can not only enhance the photosynthesis of young seedlings, but also reduce the chance of rust invasion on leaves. During the period, the amount of pest...

Embodiment 2

[0036] Biological activity observation

[0037]Refers to the effect of controlling fresh corn rust. The photosynthetic film was tested on fresh corn in six areas including Lianzhou in Qingyuan, Boluo in Huizhou, Huadu in Guangzhou, Yangchun in Yangjiang, Kaiping in Jiangmen and Doumen in Zhuhai. Product label states use. The experimental results are as follows:

[0038]

[0039]

[0040] investigation method:

[0041] Select 10 corn plants, cut the corn ears and the upper and lower 3 leaves, and classify the disease according to the area of ​​the leaves occupied by the rust spore pile. The disease grading criteria are as follows:

[0042] Grade 0: no disease spots and spores on the leaves;

[0043] Grade 1: There are a small amount of spore piles on the leaves, accounting for less than 5% of the leaf area;

[0044] Grade 3: There are a small amount of spore piles on the leaves, accounting for 6%-25% of the leaf area;

[0045] Grade 5: There is a moderate amount of ...

Abstract

The invention provides a method for preventing and controlling a fresh maize rust disease by utilizing a photosynthetic high lipid film agent, the method comprises the photosynthetic high lipid film agent and the photosynthetic high lipid film agent comprises the following components in parts by weight: 300 parts of dodecanol, 8 parts of an emulsifier, 5 parts of an auxiliary emulsifier, 40 partsof a thickening agent and 800 parts of water. According to the method for preventing and controlling the fresh maize rust disease, water solution is prepared to spray fresh maize at each growing stage. By adopting the method for preventing and controlling the fresh maize rust disease by utilizing the photosynthetic high lipid film agent, the photosynthesis rate of plants can be increased, the immunity of the plants can be provided, the invasion of rust bacteria can be effectively reduced, and effects of promoting growth and preventing diseases are achieved; the method is simple to operate, labor and time are saved.

Description

technical field [0001] The invention relates to a method belonging to the technical field of agricultural plant protection, in particular to a method for preventing and controlling fresh corn rust by using a photosynthetic high-fat film agent. Background technique [0002] Fresh corn, namely fruit or vegetable type sweet corn, waxy corn and sweet waxy corn. Fresh corn has played an important role in daily life, is loved by the public, and has begun to be widely planted across the country. Corn rust is one of the common diseases in corn cultivation and production, including common rust, southern rust, tropical rust and stem rust. Common rust and southern rust are more common in corn production areas in my country. The damage is manifested as covering corn leaves with rust spots, The stems and bracts hinder photosynthesis, eventually resulting in reduced corn yield and quality. Although common rust and southern rust are common in fresh corn production areas in the tropical an...
