Description
Technical Field
The invention relates to the field of plant growth regulators, and in particular relates to a pesticide composition for inhibiting catkin.
Background
Willow is a native tree species in China, is mainly used as an urban greening tree in the north, is planted on two sides of roads or inside parks in large quantities, is about 3 months every year, willow inflorescences (willow ears) begin to germinate, tender leaves can be simultaneously generated under the condition of proper temperature, when the willow ears are tender, the flower color is green, white cotton is generated in the old time, namely willow catkins, willow catkins flying over the sky like flying snow, flocculent substances are seed hairs on seeds, the willow catkins are typical allergens, allergic people can induce diseases once contacting the willow catkins, germs can be carried and spread in the floating process, and particularly, the willow catkins have great potential safety hazards, and if a large number of willow species are cut down and replaced, the time period is long, and the same aesthetic degree is difficult to achieve. The mode of inhibiting catkin which is commonly used at present is a medicine 'flower inhibiting No. I' which is developed by garden science research institute in Beijing and used for inhibiting catkin, namely gibberellic acid powder, the germination of the catkin is controlled by injecting willow in advance for one year, but the inhibiting effect is unstable, the cost is high, and the problems of plant diseases and insect pests and the like are easily caused by injection holes:
for example, patent application No. 201510222059.X, entitled "a poplar catkin inhibitor", includes: polyacrylamide, fulvic acid, abscisic acid, brassinolide and forchlorfenuron. Dissolving the raw materials in solvent, and spraying the agent onto tree crown with high pressure spray, wherein one spraying can be effective for about one month, and if the growth cycle of poplar and willow catkin in the year is long, the agent can be sprayed again after one month. The method is characterized in that polyacrylamide, fulvic acid, abscisic acid, brassinolide and forchlorfenuron are used for controlling newly generated catkin, but the time for the willow ear to age and grow the willow catkin is difficult to control within one or two days, one process is provided, the willow catkin formed on the day of pesticide application can only be solved by spraying twice and depending on the action mechanism mode of flocculation and weight increase of the willow catkin, the time for the willow ear to age and form the willow catkin lasts for 1-2 months, and the effect is not ideal;
for example, patent application No. 201710341763.6 entitled "method for controlling breeding of poplar flower and willow catkin" is characterized in that after the poplar trees grow spherical flower buds and willow tree spike-shaped tender shoots, the pesticide glyphosate and paraquat are proportionally mixed with water and sprayed on tree crowns by a high-pressure sprayer to make poplar flower and willow catkin wither and fall off, the paraquat is a sterilizing herbicide and can be rapidly absorbed by green tissues of plants to wither and die, has high toxicity and no specific antidote, is forbidden or strictly limited by a plurality of countries to use, is a sterilizing herbicide, has a sterilizing effect after contacting the green tissues, can make willow branches wither in a large area by spraying the two drugs, and is difficult to send out new leaves.
Therefore, in order to overcome the defects of the prior art for inhibiting the catkin, the pesticide composition for inhibiting the catkin is necessary.

an auxiliary material;
a solvent.
The naphthalene acetamide can be absorbed by stems and leaves of plants, has slow conductivity, can cause the formation of inflorescence stem abscission layers, and is a good vegetable fruit thinning agent.
Genistein is a natural isoflavone compound present in leguminous and dentate plants. Is a strong inhibitor of tyrosine protein kinase and a topoisomerase inhibitor, the tyrosine protein kinase is an important protein for controlling cell growth and differentiation, plays a key role in normal cell division and abnormal cell proliferation, and can be used for controlling the flower bud differentiation of willow.
Picloram can be absorbed through the roots, stems, leaves of plants, and transferred to and accumulated in actively growing tissues. Is a selective herbicide, and mainly aims at broad-leaved weeds in the weeding aspect.
The picloram aqueous agent and the salts thereof can be rapidly absorbed and conducted through leaves and roots, mainly act on nucleic acid metabolism, make chloroplast structures and other organelles develop and malform, interfere protein synthesis, act on meristem activities and the like, and inhibit or kill meristem cells at high concentration. According to data registered by Ministry of agriculture, the conventional concentration of the picloram used on non-cultivated land is 2400-4800 ppm, so that broadleaf weeds can be effectively controlled, the prepared pesticide is diluted by adding water before use, the picloram concentration is reduced, the use concentration is only about 250ppm, the differentiation and formation of willow inflorescences can be effectively inhibited, but no pesticide effect symptom is basically caused to the young leaves, and the selective weeding effect of the picloram does not have obvious effect on the non-broadleaf plant leaves such as the willow leaves, so that the effect of basically not damaging the young leaves is achieved.
The half-life of the picloram is 1-12 months, the toxicity is low, and meanwhile, the toxicity of the genistein and the naphthylacetamide is low, so that the low-toxicity effect of the picloram is achieved.
Furthermore, the auxiliary materials are wetting dispersant, thickening agent, rheological agent and antifreezing agent.
Further, the wetting dispersant is one or more of alkylphenol polyoxyethylene, propylene glycol block polyether, calcium dodecylbenzene sulfonate, lignosulphonate and tea saponin;
the thickening agent is one or more of xanthan gum and sodium carboxymethyl cellulose;
the rheological agent is one or more of magnesium aluminum silicate and white carbon black;
the antifreezing agent is one or more of ethylene glycol and glycerol;
the solvent is water.
The method is characterized in that the occurrence of willow catkins needs to be controlled from the growth period of plants, the genistein is introduced to inhibit the tyrosine protease, the tyrosine protein kinase is an important protein for controlling the growth and the differentiation of cells, plays a key role in normal cell division and abnormal cell proliferation, the flower bud differentiation of willow can be strictly controlled through the action of the genistein, the formation of the inflorescence of the willow is controlled from the source, and in order to ensure that the inhibition rate is highest, if part of flower buds are differentiated, the flower buds can be inhibited or killed through the picloram, and the flower buds can be killed through the synergistic effect of the thinning of the naphthylacetamide, so that the flower buds fall off, and finally the possibility of controlling the occurrence of the willow catkins is achieved.
Further, in the pesticide composition for inhibiting catkin, 1-30 parts of picloram, 0.5-5 parts of naphthylacetamide, 0.5-5 parts of genistein, 1-10 parts of wetting dispersant, 0.05-0.5 part of thickener, 0.1-2 parts of rheological agent, 1-5 parts of antifreeze agent and 42.5-96 parts of water are calculated according to parts by weight.
The inhibition of the generation of catkin needs to be regulated in the growth process of willows, and the good inhibition effect of the catkin can be achieved by inhibiting the formation of inflorescences of the willows or enabling the inflorescences to fall off before the inflorescences are mature. Through the functions of inhibiting and killing meristematic cells and selectively weeding by picloram, the growth of a new inflorescence can be quickly inhibited in the inflorescence formation period, the formed inflorescence is killed, meanwhile, the formed inflorescence is safe to a new leaf, the synergistic effect of the picloram on flower thinning is cooperated, and the synergistic effect of genistein on inhibiting tyrosinase is achieved, so that the differentiation of new flower buds can be controlled from the source, the formed inflorescence can be killed, the formed inflorescence can be fallen off, and finally the formed inflorescence is difficult to mature to form willow catkin, so that the aim of inhibiting the willow catkin is fulfilled.
