Summary of the invention
The purpose of this invention is to provide a kind of thermal fog and preparation method who contains Tebuconazole and Hostathion.It is formulated by active principle Tebuconazole and Hostathion, high boiling solvent, density adjuster and other auxiliary agents.In use make active principle gasification and cohesion with hot mist machine, in air, keep the certain height drift with superfine droplet, when running into plant, just can be adsorbable securely on plant corpuss such as plant leaf blade positive and negative and stem, be used for the control of plant pest.
The present invention adopts following technical scheme:
A kind of thermal fog that contains Tebuconazole and Hostathion is characterized in that: the mass percent of its each component of constitutive material is:
Tebuconazole 3-20%
Hostathion 15-35%
Solvent 5-30%
Surfactant 1-15%
Thickener 0.1-5%
Hot fog density conditioning agent 1-8%
Antifreezing agent 1-8%
Defoamer 0.1-1%
Surplus is a water;
Wherein, described surfactant is selected from one or more mixing in EO-PO block copolymer (OP-10 etc.), castor oil polyoxyethylene ether (BY140 etc.), polyoxyethylene nonylphenol ether (NP-10 etc.), sodium lignin sulfonate or the calcium dodecyl benzene sulfonate;
Described solvent is selected from one or more in polyaromatic solvent naphtha, mixed benzene, dimethylbenzene, the machine oil;
Described thickener is selected from one or both in polyvinyl alcohol, the xanthans;
Described hot fog density conditioning agent is selected from one or both in attapulgite, kaolin, coarse whiting, the white carbon ultra micro powder;
Described antifreezing agent is selected from propane diols, the urea one or both;
Described defoamer is selected from one or both in octanol, the dimethyl silicone polymer.
The described preparation method who contains the thermal fog of Tebuconazole and Hostathion: it is characterized in that: specifically may further comprise the steps:
(1) Tebuconazole of formula rate and Hostathion and solvent are mixed together, under agitation are dissolved into oil-phase solution;
(2) surfactant, thickener, hot fog density conditioning agent, antifreezing agent, defoamer and the water with formula rate mixes, and under agitation is dissolved into water;
(3) oil-phase solution that step (1) is made joins the aqueous phase that step (2) makes, and continuing to stir becomes aqueous emulsion;
(4) aqueous emulsion that step (3) is made filters removes a small amount of residue, gets finished product.
The described purposes that contains the thermal fog of Tebuconazole and Hostathion is characterized in that: this thermal fog is applicable to the dispenser of hot mist machine, in can be used for, the control of low culm plant damage by disease and insect.
Using method of the present invention: the thermal fog that will contain Tebuconazole and Hostathion is got it filled by every mu of ground 100-150g dosage, fully shakes up the back and adds hot mist machine explosive barrel, can be blended into smoke agent such as an amount of diesel oil or low amounts of water crop is prevented and treated.When using on plants such as wheat, rape and corn, the hot fog colloidal sol of formation can spread in plant canopy, and is deposited on plant surface uniformly, and the control efficiency of target more than 75%, is higher than the identical agricultural chemicals of other formulations.
Advantage of the present invention is:
(1) dispenser operating efficiency height, the saving of labor saves time again.Its operating efficiency is 15-20 a times of conventional spraying, is the efficient application method that is only second to the aviation operation, can save dispenser recruitment cost greatly.
(2) save agricultural chemicals, the drug effect height, the lasting period is long.Use thermal fog of the present invention for every mu, only need to reach same drug effect with the 1/2-2/3 of other formulation active ingredients of identical agricultural chemicals.Its main cause is that thermal fog medicine grain diameter is more much lower than regular dosage form, and active ingredient is more evenly distributed on plant, contacts with target is easier.
(3) resistance of rainwater washing against.Conventional pesticide formulation such as wetting powder, missible oil and suspending agent are converted water spray during use, because plant surface tension force is lower, thereby the easy landing of droplet, can be washed away when especially meeting rain, and hot fog particles is deposited on the plant, because surface tension own is extremely low, and particle diameter is little, strong with the plant surface absorption affinity, penetration power is strong, easier entering in the target body, thereby adaptive capacity is stronger, and dispenser also can do as usual when spotting.
(4) can be used in, low culm plant.Thermal fog in the past is lower owing to density with the hot mist of hot mist machine ejection, diffuse into atmosphere with ascending air easily, not only drug effect descends, also cause environmental pollution easily, especially more obvious when the higher or fine ascending air of wind-force is strong, the plant that only is applicable to tall and big concealment is (as forest, fruit tree) or relatively sealed space is (as the warehouse, the greenhouse), and the present invention is owing to used hot fog density regulation technology, in use make active component gasification and cohesion with hot mist machine, form aerosol with superfine droplet (8-15 μ m accounts for more than 90%), in air, keep the certain height diffusion, when running into plant, just can be adsorbable securely in plant surface, therefore can be at wheat, corn, in the rape etc., use on the low culm plant.
(5) environmental pollution is little, can reduce labor intensity of operating personnel simultaneously and reduce the contamination risk.Conventional spraying endangers seriously operating personnel, particularly situation is even more serious when growing middle and later periods such as corn, the dispenser of rape field, soup runs off in a large number in soil simultaneously, pollute, and spray thermal fog, the people carries on the back the dispenser with the wind of hot mist machine, little field piece (in 2 mu) is not with going to the field, minimum to the human influence, droplet overwhelming majority deposition also is adsorbed in plant surface, and is very little to environmental influence.
(5) water saving.Conventional spraying more than every mu of water 50kg, and only needs spraying preparation 100-150g to get final product with every mu of thermal fog of the present invention.This advantage is particularly suitable for the water-deficient area, and is especially suitable to corn, wheat, the rape of middle and later periods.
