Problems solved by technology

[0010] Chinese patent CN201310743590.2 discloses a suspending agent of prochloraz and iprodione, but prochloraz is a kind of solid drug that is difficult to crush, and it is difficult to operate by directly adding it and iprodione into a grinder for grinding. The suspension rate is low, the stability of the dosage form is not good during storage, there are problems such as precipitation of water, crystallization at low temperature, etc.
Patent CN200810199165.0 discloses a compound suspoemulsion of prochloraz and other bactericidal ingredients (including iprodione). Only the compounding of two bactericidal active ingredients improves the bactericidal effect, but the invention involves a relatively complicated process. More equipment and high equipment investment
[0011] Patent CN02818140.9 discloses a compound composition of iprodione and pyrimethanil or other fungicidal active ingredients or plant growth regulators, but this composition is only suitable for field crops and does not involve post-harvest preservation of fruits and vegetables

Embodiment 11

[0051] The application object is spinach.

[0052] Experimental treatment: select fresh spinach with similar length, thickness, and appearance, remove rotten and mechanically injured spinach, and divide them into different groups on average. Dilute the suspoemulsion prepared by the method shown in Examples 1 to 10 by adding 1 to 10 times of water to 50 times, and spray On spinach, each experimental treatment was repeated 3 times. After the treatment was completed, the spinach was dried at room temperature, and then put into a 0.02mm polyethylene fresh-keeping bag. At room temperature (25°C), the above-mentioned suspoemulsion was observed after 5 days. The green effect and rot rate of spinach. The experimental setting control (CK) is the water treatment group.

[0053] The decay rate is calculated as follows:

[0054] Rot rate (%) = weight of rotten spinach / weight of total spinach × 100

[0055] Greening effect: It is divided into the following 5 grades, and the scores of ...

Embodiment 12

[0060] Taking garlic sprouts as the experimental object

[0061] Suspoemulsion 8 was prepared according to the method shown in Example 8 and diluted with water at a ratio of 1:100. Fresh garlic sprouts of the same variety, length, thickness, and appearance were selected, and the sprouts were sprayed. Each experimental treatment was repeated 3 times. Chill and store.

[0062] As a control, the homemade 5% prochloraz aqueous emulsion and 5% iprodione wettable powder were used to dilute the garlic sprouts with water at a ratio of 1:100, put into the warehouse, pre-cool, and store.

[0063] After storage for 4 months, the fresh-keeping effect and anti-mildew situation of the above-mentioned suspoemulsion on garlic sprouts were observed.

[0064] The mold growth rate is calculated as follows:

[0065] Mold growth rate (%) = number of moldy garlic roots / total garlic roots × 100

[0066] Fresh-keeping effect: It is divided into the following 5 grades, and the scores of each grade ...

Abstract

The invention discloses suspoemulsion. The suspoemulsion is prepared from active ingredients including, by weight, 1-5% of prochloraz, 1-5% of iprodione and 0.01-2% of plant growth regulator, and the balance auxiliary components which are allowed to be used in pesticide and can be accepted and water. The plant growth regulator is at least one of thidiazuron, naphthylacetic acid, sodium alpha- naphthaleneacetate, potassium alpha- naphthaleneacetate, benzyl aminopurine and brassinolide.

Description

technical field [0001] The invention relates to a suspoemulsion and a preparation method thereof, in particular to a suspoemulsion containing prochloraz, iprodione and a plant growth regulator, and belongs to the technical field of pesticide preparation processing. Background technique [0002] Prochloraz, imidazole fungicides, trade name is SportaK (SportaK), chemical name: N-propyl-N-[2-(2,4,6-trichlorophenoxy)ethyl]-imidazole -1-formamide, molecular formula: C 15 h 16 C l3 N 3 o 2 , the chemical structural formula is as follows: [0003] [0004] Prochloraz is a synergistic, broad-spectrum, and environmentally-friendly imidazole fungicide, which prevents the growth of bacteria by inhibiting the biosynthesis of sterols in the bacteria, and has the characteristics of strong systemic conductivity, good quick-acting, and long-lasting effects At the same time, it has multiple functions such as prevention, protection and treatment. Used to control banana anthracnose, ...
