Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a functional foliar fertilizer.
Background
Thrips inhabiting on crop vegetables in China are more than 40, wherein more serious Thrips (T.tabaci Lindeman), palmi Karny, huang Jima (T.flavus), yellow chest Thrips (T.hawaiiensis) and color Thrips (T.color) are among Thrips (threps Linnaeus); frankliniella (Frankliniella) Frankliniella (f.occidentalis), frankliniella (f.intonsa) and Frankliniella (f.tenuicornis). The thrips can absorb juice of vegetable tender tips and other parts by adults and nymphs, so that tender leaves shrink, malformation, formation of dead spots and other different damages are generated, photosynthesis of crops is seriously affected, and crop yield is reduced. In addition, the fruit setting period is harmful and can cause early ageing, rigidification or yellowing of crops in the young fruit period. Secondly, thrips can also spread plant virus diseases.
In agricultural production, the pesticide is sprayed to prevent and treat diseases and insect pests such as thrips. The common medicines for preventing and treating thrips comprise spinetoram, chlorfenapyr, emamectin benzoate and the like, but the prevention and treatment effect of the thrips is reduced year by year along with the continuous development of drug resistance of the thrips to the existing medicines. Therefore, the development of a safe and efficient novel medicament for preventing and treating thrips has important significance. At present, no report on compounding wintergreen oil with doramemycin, tolfenpyrad or spinetoram is known, and the method can provide support for developing novel medicaments.
Foliar fertilizer is a type of fertilizer that avoids the application of nutrients to the leaves of crops and serves its function by being absorbed by the leaves. Practices prove that the foliar fertilizer has the advantages of rapid fertilizer efficiency and high fertilizer utilization rate. However, the existing foliar hypertrophy is mainly used for providing nutrients for the growth of crops, and does not have the efficacy of preventing and controlling plant diseases and insect pests.
Disclosure of Invention
The invention aims to provide a functional foliar fertilizer which comprises a fertilizer and an insecticidal composition, wherein the fertilizer part can provide nutrients for the growth of crops, and the insecticidal composition part can effectively prevent and control insect pests on the crops, so that the dual effects can be achieved by one-time application; in addition, the synergistic effect of the wintergreen oil and doramectin, tolfenpyrad or spinetoram in the insecticidal composition can improve the prevention and treatment effect on thrips, and can provide support for developing and developing safe and efficient novel medicaments for preventing and treating thrips.
In order to achieve the above purpose, the present invention provides the following technical solutions:
the insecticidal composition is prepared from wintergreen oil and doramemycin, tolfenpyrad or spinetoram according to a ratio of 1-300: 150-1.
More specifically, the mass ratio of the wintergreen oil to the doramemycin is 1-9:9-1.
More specifically, the mass ratio of the wintergreen oil to the tolfenpyrad is 1-25:7-1.
More specifically, the mass ratio of the wintergreen oil to the spinetoram is 1-20:20-1.
The invention also provides a functional foliar fertilizer comprising the insecticidal composition of any one of claims 1 to 4.
More specifically, the functional foliar fertilizer is prepared by mixing the following components in percentage by mass: 1-5% of the insecticidal composition, 40-60% of fertilizer, 1-10% of dispersing agent, 1-8% of wetting agent and the balance of filler; wherein the fertilizer is selected from one or more of potassium nitrate, monopotassium phosphate, potassium sulfate, zinc sulfate, potassium chloride, ammonium chloride and sodium octaborate tetrahydrate; the dispersing agent is sodium lignin sulfonate; the wetting agent is prepared from sodium dodecyl benzene sulfonate and sodium dodecyl sulfate according to the weight ratio of 1:1, mixing the materials according to the mass ratio; the filler is one or more selected from the group consisting of clay, kaolin, diatomite, pyrophyllite, light calcium hydrochloride and attapulgite.
Compared with the prior art, the invention has the following beneficial effects:
(1) The insecticidal composition provided by the invention is composed of wintergreen oil and doramectin, tolfenpyrad or spinetoram according to a certain mass ratio, has a synergistic effect on insect pests such as thrips, can improve the control effect on the insect pests, reduces the application amount of the agent, and is beneficial to reducing the control cost of the insect pests; meanwhile, the development of insect pest resistance can be delayed, and support can be provided for developing and developing safe and efficient novel medicaments for preventing and treating thrips.
(2) The functional foliar fertilizer provided by the invention contains the fertilizer and the insecticidal composition, wherein the fertilizer part can provide nutrients for the growth of crops, and the insecticidal composition part can effectively prevent and control insect pests on the crops, so that the dual effects can be achieved by one-time application.
