Description
Technical Field
The invention relates to the technical field of pesticide preparation, in particular to a preparation method of a plant essential oil grain storage pesticide slow-release agent.
Background
Grain is an important commodity and strategic material for the county of the related countries, and has very important significance for economic development and social stability. However, during grain storage, losses are often caused by pests. Therefore, the improvement of the grain storage technology and the prevention and control of the grain storage pests are particularly important.
The plant essential oil is extracted from flower, leaf, root, bark, fruit, seed, resin, etc. of herbaceous plant by distillation and squeezing. Research shows that the plant essential oil has various biological activities of killing pests, sterilizing, resisting viruses and the like, and has synergistic effect on various pesticides. Because of its volatility, it is especially suitable for controlling pests in household environment.
In the prior art, the essential oil is directly used for grain storage and disinsection or is prepared into microcapsules. For example, chinese patent CN101420848A provides an application of microencapsulated essential oil, which can be applied to grain storage for insecticidal purposes. Because essential oil has volatility, is difficult to spray evenly, and it volatilizes very fast simultaneously, directly utilizes it to carry out the spraying to grain, causes the waste easily, and long-term storage effect is relatively poor. The patent technology makes essential oil into a microcapsule form, overcomes the problem of essential oil volatilization, but the preparation process of the microcapsule is complex, essential oil loss is caused, waste is caused, the slow release effect of the essential oil capsule is not good enough, and the insect prevention effect is not ideal.

Based on the method, the preparation method is simple, the prepared slow release agent can prolong the volatilization time of the essential oil, the insecticidal effect is good, and the grain storage time is prolonged, and the number of microorganisms can be effectively reduced when the wheat fumigated by the slow release agent is used for preparing the noodles, so that the noodles are not easy to rot and deteriorate, and the storage time is prolonged.
The preparation method of the plant essential oil grain storage insecticidal slow release agent comprises the following steps:
(1) sieving diatomite with a 180-220 mesh sieve, filling the diatomite into a sealing bag, placing the sealing bag in a dryer, and drying for later use;
(2) mixing the diatomite and the compound essential oil, uniformly stirring by using an electric stirrer, sealing in a dark place, and balancing for 0.5-1.5 hours to ensure that the diatomite and the compound essential oil are fully absorbed;
(3) weighing magnesium stearate serving as a lubricant, adding the magnesium stearate into the mixture obtained in the step (2), uniformly stirring, and balancing for 25-35 min;
(4) weighing 2.00g of the uniformly stirred mixture obtained in the step (3), putting the mixture into a tabletting machine model, tabletting under the pressure of 12-18 MPa for 20-40 s each time, taking down, demoulding, uniformly coating a layer of coating agent, and standing in the dark for 0.5-1.5 h to form the coating agent, so as to prepare the vegetable essential oil grain-storage insecticidal sustained-release tablet;
(5) and filling the prepared tablets into a sealed bag, placing the sealed bag into a dryer, and drying the sealed bag for later use.
Preferably, the compound essential oil in the step (2) is prepared from mint essential oil and basil essential oil according to a mass ratio of 1-2: 1-2.
Preferably, the mass ratio of the diatomite to the compound essential oil in the step (2) is 1: 3-1: 4.
preferably, the addition amount of the magnesium stearate in the step (3) is 0.9-1.2% of the total mass of the mixture prepared in the step (2).
Preferably, the coating agent in the step (4) is sodium alginate and chitosan, wherein the mass ratio of sodium alginate to chitosan is 1: 1-1: 2.
the invention also aims to provide the plant essential oil grain storage insecticidal slow release agent prepared by the preparation method and the application thereof: the plant essential oil grain storage insecticidal slow release agent is placed in a position of 25-35 cm of grain surface, and the addition amount of the slow release agent is 1-2 tablets/50 kg.
Compared with the prior art, the invention has the following advantages: the mint essential oil and basil essential oil have the effect of fumigating and killing stored grain pests, the surface of the diatomite has a plurality of pores with adsorption effect to adsorb the essential oil, and the magnesium stearate is used as a lubricant, so that the prepared slow release agent has good fluidity and compressibility. The tabletting process is relatively simple, the adsorption rate of the essential oil is high, and a film coating agent is coated after tabletting to seal partial holes, so that the effect of slowly releasing the essential oil can be achieved, the volatilization time of the essential oil can be prolonged, grains can be stored better, and the microbial quantity can be effectively reduced.
