Pesticide composition for inhibiting catkin

Abstract

The invention relates to a pesticide composition for inhibiting catkin. The pesticide composition is prepared from the following components: picloram, naphthylacetamide, genistein, a wetting dispersant, a thickener, a rheological agent, an anti-freezing agent and water. The willow inflorescence removing method has the beneficial effects that the willow inflorescence removing rate is remarkably increased, and meanwhile damage to tender leaves is extremely small; toxicity is low, safety is achieved, no pollution is caused to the environment, and cost is low; the drug action time is long, and supplementary application is not needed in a short time.

Description

technical field [0001] The invention relates to the field of plant growth regulators, in particular to a pesticide composition for inhibiting catkins. Background technique [0002] Willow is a native tree species in my country. It is mainly used as an urban greening tree in the north. It is planted in large quantities on both sides of the road or inside the park. Around March every year, the willow inflorescence (willow spike) begins to germinate. When the temperature is suitable, young leaves will be born at the same time. When the ear is tender, the flower color is green, and when it is old, white cotton is born, which is catkins. The catkins flying all over the sky are like snowflakes. The flocculent material is actually the seed hair on the seeds. Catkins are typical allergens. , it may induce diseases, and at the same time, it may carry and spread germs during the floating process, especially for allergic people. degree.

[0002] Willow is a native tree species in my country. It is mainly used as an urban greening tree in the north. It is planted in large quantities on both sides of the road or inside the park. Around March every year, the willow inflorescence (willow spike) begins to germinate. When the temperature is suitable, young leaves will be born at the same time. When the ear is tender, the flower color is green, and when it is old, white cotton is born, which is catkins. The catkins flying all over the sky are like snowflakes. The flocculent material is actually the seed hair on the seeds. Catkins are typical allergens. , it may induce diseases, and at the same time, it may carry and spread germs during the floating process, especially for allergic people. degree

The commonly used method of inhibiting catkins is the drug "Yihua No. 1" for inhibiting catkins developed by the Beijing Academy of Landscape Sciences, that is, gibberellic acid powder. The germination of catkins is controlled by injecting willows one year in advance, but The inhibitory effect is unstable, and the cost is high, and the injection hole is easy to cause problems such as diseases and insect pests:

That is, it discloses a method of using polyacrylamide, fulvic acid, abscisic acid, brassinolide, and forchlorfenuron to control the newly formed catkins, but it is difficult to control the time for catkins to grow within one or two days. , there is a process, through one or two spraying, relying on the mechanism of flocculation and increasing the weight of catkins can only solve the catkins formed on the day of spraying, and the aging of willow ears to form catkins lasts for 1 to 2 months, the effect not ideal;

[0004] Another example is the invention with the patent application number 201710341763.6 and the title "Birth Control Method for Poplar Catkins". Add water and use a high-pressure sprayer to spray the liquid on the crown of the tree, so that the poplar catkins will turn yellow and fall off. Paraquat is a herbicide that can be quickly absorbed by the green tissue of the plant, causing it to die. It is highly toxic and has no special detoxification Glyphosate has been banned or strictly restricted in use by many countries. Glyphosate is also a herbicide that kills green tissues. It has a killing effect after contacting green tissues. While spraying the two drugs at the same time, it can make willow ears fall off, but it is harmful to the herbicide. The damage to the tree body is also great, and the willow branches will die in large areas, making it difficult to produce new leaves.
