Abstract
A soluble liquid insecticide for preventing and eliminating the pests of cotton, vegetables, fruit trees, etc is prepared from fenpropathrin, non-benzene assistant, non-benzene solvent, emulsifier and synergist. It has high effect and safety.
Description
The present invention relates to agricultural chemicals, be a kind of be one group of soluble liquid insecticides of raw material with fenpropathrin (fenpropathrin), product is one group of efficient, broad spectrum pesticide.Be applicable to the control of crop pests such as fruit tree, vegetables, cotton.Insect preventive effects such as cotton bollworm, citrus red mite are better than conventional dose goes out and sweeps agent.
For a long time, the used main medicament of China's agricultural insect pests control is organophosphorous pesticide and pyrethroid built cream preparation.Because long-term single use, pest resistance to insecticide is on the rise, and preventive effect reduces.And a large amount of poisonous uses that contain benzene solvent cause health harm to the producer, user in the cream preparation.Simultaneously behind such pesticide application farmland, a large amount of toxic solvents water that permeates the ground, polluted agricultural land, waters.At present, many developed countries to have banned use of dimethylbenzene be solvent preparation agricultural chemicals.Thereby, press for more efficient, low toxicities, novel form comes out.Fenpropathrin is a kind of efficient, wide spectrum pyrethroid insecticides, have tag, stomach toxicity, repellent action.Except that feature with general pyrethroid, to the also good preventive effect of tool of various crop tetranychid, we are through repetition test, succeed in developing by fenpropathrin, respectively efficient, the environmental protection novel form that processes with Avermectin, ivermectin, emamectin-benzoate, no benzene cosolvent, non-toluene solvent, emulsifier, synergist etc.
The object of the present invention is to provide a kind of preparation rationally, dispersed, emulsifiability is good, to the producer and user's safety, with eco-friendly soluble liquid insecticides.
Implementation method of the present invention below is described in detail in detail:
In the soluble liquid insecticides of the present invention (by weight percentage), fenpropathrin 1～25%, ivermectin (or Avermectin, or emamectin-benzoate) 0.1～5%, no benzene cosolvent 0～30%, emulsifier 1～30%, bleeding agent 0～15%, synergist 0～5%, antioxidant 0.1～1%, all the other are non-toluene solvent.
Avermectin of the present invention is the tunning of A Foman streptomycete Streptomyces avermitilis, the mixture of being made up of eight quite similar homologues of structure.The general B that uses more

Emamectin-benzoate of the present invention is a kind of mixture that contains two kinds of Main Ingredients and Appearances, and a kind of is 4 " (table methylamino)-4 "-deoxidation Avermectin B greater than 90%

The method for making of this soluble liquid is earlier with former powder of fenpropathrin and Avermectin (or ivermectin, or emamectin-benzoate) former powder is dissolved in the no benzene cosolvent, add synergist, emulsifier, bleeding agent, antioxidant again, fully stir, mix, leave standstill, filter, weigh and make.
The present invention can provide by following example:
Example one: take by weighing the former medicine 11.1kg of 90% fenpropathrin, the former powder 0.21kg of 94% Avermectin, or the former powder 0.22kg of 90% emamectin-benzoate, add no benzene cosolvent 10kg, it is fully dissolved, add synergist 2kg again, compound emulsifying agent 15kg, penetrating agent JFC 2kg, antioxidant BHT 0.5kg adds non-toluene solvent to 100kg.Fully leave standstill behind the stirring and evenly mixing, filter, promptly get 10.2% fenpropathrin Avermectin soluble liquid or 10.2% fenpropathrin emamectin-benzoate soluble liquid.
Example two: take by weighing the former medicine 16.7kg of 90% fenpropathrin, the former powder 0.54kg of 92% ivermectin adds no benzene cosolvent 10kg, and it is fully dissolved, add synergist 2kg again, compound emulsifying agent 18kg, penetrating agent JFC 2kg, antioxidant BHT 0.5kg, add non-toluene solvent to 100kg, fully behind the stirring and evenly mixing, leave standstill, filter, promptly get 15.5% fenpropathrin ivermectin soluble liquid.
Example three: this example is that 10.2% fenpropathrin Avermectin soluble liquid and chemical plant, Shijiazhuang, Hebei 1.8% acetamiprid missible oil, Pingyue County, Guilin vegetalization factory 20% fenpropathrin milk oil are prevented and treated the comparative test of citrus red mite drug effect, 6 processing are established in test, every processing repeats randomized arrangement 4 times.Every sub-district is by fixed 5 points of 5 point samplings, and investigation insect population radix before 2 blades of every some random searching, medicine was investigated remaining mite number in 1 day, 3 days, 10 days, 20 days behind the medicine, calculated preventive effect.(the results are shown in Table 1)
Table 1 10.2% first cyanogen A Wei suitable solvents control citrus red mite field control effectiveness test
| Handle | Dosage (g/hm 2) | Insect population radix (head) | Preventive effect (%) | |||
| 1d | 3d | 10d | 20d | |||
| Doubly 10.2% first cyanogen A Wei SL2500 times 1.8% acetamiprid EC2000 times 20% first cyanogen EC1000 times of 10.2% first cyanogen A Wei SL2000 | 24.8 19.8 4.4 97.2 | 2944 4184 3082 3495 | 100a 100a 99.1b 100a | 93.8ab 93.0ab 87.4b 97.1a | 83.3b 75.4c 70.1c 97.2a | 69.2a 51.6b 44.7b 73.1a |
By this example as seen, use 10.2% first cyanogen Avermectin soluble liquid control citrus red mite that good preventive effect is arranged, using pesticide volume is that 20% first cyanogen cream 20～26% can reach good quick-acting and lasting effect.Therefore use 10.2% first cyanogen abamectin emulsifiable concentrate, the agricultural chemicals usage amount descends significantly, and has alleviated the pollution of poisonous chemical solvent to environment.
