Abstract
The invention discloses a compound emulsifiable concentrate for prevention and treatment of wheat stripe rust, and is characterized in that the compound emulsifiable concentrate is prepared from the following raw materials in parts by weight: 5-10% of hexaconazole, 1-3% of gibberellin, 8-20% of Jiean-peptide, 1-5% of a dispersion agent, 65-80% of a solvent, 1-2% of an emulsifier, 3-10% of validamycin, 10-20% of imidacloprid, and 1-3% of naphthaleneacetic acid sodium. Prevention and control are combined, while the wheat stripe rust is prevented and treated, the compound emulsifiable concentrate has an effect on promoting wheat chlorophyll synthesis, ensures adequate nutrition supply, enhances accumulation of nutrients in wheat, and improves the quality.
Description
Technical field
The invention belongs to crop pest control technical field, particularly relate to a kind of compounded cream preventing and treating stripe rust of wheat.
Background technology
Wheat rust is to record disease the earliest in the world, is divided into stripe rust, stem rust, leaf rust three kinds, be China's Semen Tritici aestivi occurs the widest, endanger a maximum class disease.Three kinds of rust all have generation in China various places, but occur the most general and serious with stripe rust of wheat.In recent years, stripe rust of wheat occurs mainly in the Winter Wheat Area on the ground such as northwest, southwest, North China and the Huaibei and the spring wheat district of northwest；Stem rust of wheat occurs mainly in the Winter Wheat Area of northeast, the Inner Mongol, northwest, southwestern spring wheat district and Yangze river and Huai river and southeastern coast；Wheat leaf rust occurs mainly in southwest in the past, at present in North China, northwest, various places, northeast also gradually serious.
After Semen Tritici aestivi generation rust, the nutrient in plant body is robbed in a large number, and chlorophyll is damaged, and photosynthesis area reduces, a large amount of sorus break through wheat leaf, straw epidermis, make evaporation capacity increase, and dehydration is serious, impact grouting, thus seed is not plump thin, protein content reduces, and yield reduces, and quality deteriorates.As rust occurs early, the normal growth of wheat root, Mai Ye being had extreme influence, the bar rust energy underproduction 73～85%, leaf rust is 49～67%, and stem rust is 74～84%.Production loss is except with generation sooner or later, outside the Pass weight has, also different because of conditions such as varietal resistance, weather and cultivations.
At present, prevention and controls about stripe rust of wheat is a lot, the technology report of " bacteria and pest killing compound agent for wheat " it is entitled as patent CN102057911A discloses, disclose the cream bacteria and pest killing compound agent of " olefin conversion 1～15%, Triadimenol 1～30%, imidacloprid 1～10%, emulsifying agent 5～10% and solvent are mended to 100% ", the bactericidal action of this built agent is notable, can also delaying drug resistance development, and double eliminate aphis, the advantage that there is a dispenser and multiple pest and disease damage can be prevented and treated.But, after this drug use, wheat growth is produced certain ill effect, although used by be re-dubbed and be divided into hypotoxicity antibacterial, but while killing pest and disease damage, also killed beneficial insect, the later stage of Semen Tritici aestivi is eared by this, grouting etc. has a negative impact.Further, when this composite bactericide consumption is too much, the edible safety of Semen Tritici aestivi is caused impact.
Summary of the invention
It is an object of the invention to: overcome the deficiency of existing bacteria and pest killing compound agent for wheat, it is provided that one both can sterilization and disinfestation, prevent and treat stripe rust of wheat；Semen Tritici aestivi nutrition will not be injured again, also Semen Tritici aestivi can be had the compounded cream of certain promotion.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of compounded cream preventing and treating stripe rust of wheat, it is characterised in that: it is made up of the raw material of following weight portion: hexaconazole 5～10%, gibberellins 1～3%, Jiean-peptide 8～20%, dispersant 1～5%, solvent 65～80%, emulsifying agent 1～2%, jingganmycin 3～10%, imidacloprid 10～20%, Nafusaku 1～3%.
Further, described dispersant is at least one in glycerol monostearate, glyceryl tristearate.
Further, described solvent is the mixed liquor of methanol, ethanol, and its mixed proportion is: methanol: ethanol=1～60:100～40.
As preferably, described a kind of compounded cream preventing and treating stripe rust of wheat, it is characterised in that: it is made up of the raw material of following weight portion: hexaconazole 8%, gibberellins 1.5%, Jiean-peptide 15%, dispersant 2.5%, solvent 75%, emulsifying agent 1.2%, jingganmycin 5.5%, imidacloprid 18%, Nafusaku 1.2%.
Compared with existing bacteria and pest killing compound agent for wheat, the beneficial effects of the present invention is:
1, the composite bactericide of the present invention is on the basis of original antibacterial, improves the ratio of the feature of environmental protection, low murder by poisoning composition, and if Jiean-peptide is to extract from bacillus subtilis, its toxicity is lower, but stripe rust has obvious preventive and therapeutic effect；Further, this material is identical with hexaconazole collaborative, can promote bactericidal effect so that germicidal efficiency improves about 15%.
2, the composite bactericide of the present invention is no longer simple bactericidal action, have employed the composition proportion preventing to combine with preventing and treating, effect by the composition such as gibberellins, Nafusaku, ensure the chlorophyllous normal synthesis of Semen Tritici aestivi, fundamentally prevent the generation of stripe rust, and enhance the photosynthesis of Semen Tritici aestivi, improve nutrient composition content, improve wheat quality.
3, the composite bactericide of the present invention has easy to use, to advantages such as harm are little, during use, only need to be mixed with tap water by medicament, can spray, do not have the situation sticking human body or Semen Tritici aestivi after spraying after stirring.
Detailed description of the invention
Below in conjunction with specific embodiment, technical scheme is described further, but is not intended to interest field.
Embodiment 1
A kind of compounded cream preventing and treating stripe rust of wheat, is made up of the raw material of following weight portion: hexaconazole 5%, gibberellins 1%, Jiean-peptide 8%, dispersant 1%, solvent 65%, emulsifying agent 1%, jingganmycin 3%, imidacloprid 10%, Nafusaku 1%.
Wherein, described dispersant is glycerol monostearate.
Described solvent is the mixed liquor of methanol, ethanol, and its mixed proportion is: methanol: ethanol=55:50.
Embodiment 2
A kind of compounded cream preventing and treating stripe rust of wheat, is made up of the raw material of following weight portion: hexaconazole 8%, gibberellins 1.5%, Jiean-peptide 15%, dispersant 2.5%, solvent 75%, emulsifying agent 1.2%, jingganmycin 5.5%, imidacloprid 18%, Nafusaku 1.2%.
Embodiment 3
A kind of compounded cream preventing and treating stripe rust of wheat, is made up of the raw material of following weight portion: hexaconazole 10%, gibberellins 3%, Jiean-peptide 20%, dispersant 5%, solvent 80%, emulsifying agent 2%, jingganmycin 10%, imidacloprid 20%, Nafusaku 3%.
Embodiment 4
The compounded cream preventing and treating stripe rust of wheat embodiment 1～3 prepared and tap water, according to after 1:300 times of liquid dilution, directly spray in morbidity Semen Tritici aestivi, sprayed once every 15 days, after having squirted, judge effect according to the situation of preventing and treating of stripe rust every time.
Spraying first, effective percentage is 97%；Secondary sprays, and effective percentage is 87%；Spraying for three times, effective percentage is 85%.As can be seen here, owing to repeatedly spraying so that protection from pest insects strengthens, and its effective percentage declines to some extent, but after three times, effective percentage is basicly stable, say, that stripe rust of wheat is had good prevention effect by the compound sterilizing cream of the present invention.
