Description
Technical field
The present invention relates to pesticide control technical field, the bactericidal composition of especially a kind of bromothalonil and pentachloronitrobenzene.
Background technique
Since reform and opening-up, China's agricultural is rapidly developed, and is also increased year by year the demand of pesticide, but crops
Disease is mostly the compound generation of multiple diseases, is applied alone a kind of pesticidal effects bad, is also easy to produce drug resistance, drug effect is caused to decline, and more
Often there is effective component there are antagonism in kind combined use of pesticides, configures the problems such as complex work amount is big, and dosage is big；
On the other hand, use of the organic solvent on pesticide is increasingly subject to limit, and does not have to or lack as far as possible with organic solvent be pesticide hair
The inexorable trend of exhibition, the dosage form of pesticide need continuous update, so that pesticide be promoted to control more along a medicine, save medicine saving of labor, benefit
Significantly, the direction of low toxic and environment-friendly is developed.Bromothalonil, english common name: bromothalonil, chemical formula: C6H6Br2N2, change
Scientific name claims: 1,2- bis- bromo- 2,4- dicyanobutane, be a kind of wide spectrum, efficiently, the fungicide of low toxicity, can inhibit and root out fungi,
Corps diseases are had preferable preventive effect by the growth of bacterium, algae, have special efficacy to anthracnose, while the medicament itself has
The activity of a variety of enzymes in irritating crop body increases photosynthesis, keeps plant leaf color dark green, healthy and strong, improves crop quality and produces
Amount.It is widely used in the diversified economies crop such as fruit tree, grape, vegetables, cotton, tobacco, flowers, it is prevention and treatment anthracnose, scab, white
A variety of fungoids, bacterial disease such as powder disease, rust, bacterial wilt.Pentachloronitrobenzene, english common name: quintozine changes
Formula: C6C15NO2, it is a kind of organic nitrogen protective fungicide efficiently, less toxic, sterilizing power is strong.To the seedling stage disease of various vegetables
Harmful and soil infection disease has preferable control efficiency.There is special efficacy to disease caused by Rhizoctonia, and to various vegetables, medicine
Material, flowers, nursery stock, cereal crops, the damping-off of southern and northern fruit tree, anthracnose, sclerotiniose, samping off, root rot, angular leaf spot,
The diseases such as canker, root blight, southern blight, clubroot have preferable prevention and treatment and radical cure effect.Using the Bactericidal composite of compounding
Object can effectively delay the generation of disease drug resistance, and reduce Pesticide use number and usage amount, the technology of R&D institution and enterprise
Personnel have made intensive studies the recipe determination of bromothalonil and pentachloronitrobenzene, it is found that bromothalonil and pentachloronitrobenzene carry out group
Closing has synergistic effect to multiple diseases prevention and treatment in certain proportional region, researches and develops the micro emulsion of bromothalonil and pentachloronitrobenzene composition
Agent and aqueous emulsion remain the technical problem not yet overcome although making some progress in practice.
Summary of the invention
It is an object of the invention to overcome the above deficiency, the Bactericidal composite of a kind of bromothalonil and pentachloronitrobenzene is provided
Object after compounding bromothalonil with two kinds of effective components of pentachloronitrobenzene, using the different mechanism of action, has complementary advantages, widens and kill
Bacterium spectrum, has apparent synergistic effect, has the characteristics that efficient, low toxicity, low-residual, to diseases such as crop damping-off, anthracnose
Effect is prevented with good, the lasting period is long, the generation of effective delaying drug resistance.The formulations of pesticide that the bactericidal composition is prepared are micro-
Emulsion or aqueous emulsion reduce the usage amount of organic solvent, and product toxicity is low, and environmental pollution is small, and use is safe, protect crops
Increasing both production and income increases the economic well-being of workers and staff of peasant.
The technical solution adopted by the present invention to solve the technical problems is: a kind of killing containing bromothalonil and pentachloronitrobenzene
