Embodiment 1

[0029] Embodiment 1 formula screening

[0030] 1. Method

[0031] (1) Sclerotinia is caused by fungi. Conidia are mainly spread by airflow and are easy to disperse. The bacteria show strict parasitic specialization or selectivity to plant organs.

[0032] The invention adopts a growth rate method to measure the inhibitory effects of active ingredients on the growth of sclerotinia sclerotiorum and rhizoctonia solani respectively. On the basis of the preliminary test, the water-soluble graphene oxide, nichloramine and triphenyltin hydroxide raw materials were made into a series of concentrations of liquid medicines with methanol as a solution, and then the liquid medicines were added in a proportion of 1%. In the PDA medium that has been melted and cooled to room temperature, shake well, pour it into a sterilized Petri dish (Φ90mm) to make a plate with medicine, repeat each treatment four times, and use the treatment of adding sterile water as the blank control ; Use a sterili...

Embodiment 2

[0047] Example 2 95% water-soluble graphene oxide-chloronitroamine-triphenyltin hydroxide wettable powder

[0048] (1) The active ingredient is composed of the following components by mass percentage: 30% of water-soluble graphene oxide, 30% of nichloramine, and 35% of triphenyltin hydroxide. Among them, the water-soluble graphene oxide is composed of fatty acid polyoxyethylene methyl ether and graphene oxide with a mass ratio of 5:1.

[0049] (2) The auxiliary components are prepared from the following components in parts by weight: 15 parts of phosphoric acid ester, 7 parts of gum arabic, 0.4 part of butyl glycidyl ether, 0.2 part of sodium aluminosilicate, 0.2 part of citric acid and attapulgite 35 servings.

[0050] (3) Weigh each component according to the above formula, add the active ingredient and various auxiliary ingredients into the cone mixer and mix uniformly, so that the sum of the mass percentage of the active ingredient and the auxiliary ingredient is 100%, an...

Embodiment 3

[0051] Example 3 80% water-soluble graphene oxide-nitrochloramine-triphenyltin hydroxide wettable powder

[0052] (1) The active ingredient is composed of the following components by mass percentage: 24% of water-soluble graphene oxide, 24% of nichloramine, and 32% of triphenyltin hydroxide.

[0053] (2) The auxiliary components are prepared from the following components in parts by weight: 15 parts of phosphoric acid ester, 7 parts of gum arabic, 0.4 part of butyl glycidyl ether, 0.2 part of sodium aluminosilicate, 0.2 part of citric acid and attapulgite 35 servings.

[0054] (3) The preparation method is the same as in Example 2.

Abstract

The invention discloses a sclerotiniose prevention and control graphene pesticide preparation and provides a graphene pesticide composition composed of water-soluble components such as graphene oxide,dicloran and triphenyltin hydroxide and auxiliary components. The water-soluble components such as graphene oxide, dicloran and triphenyltin hydroxide at the weight ratio of (1-30) : (1-30): (1-30) serve as active ingredients. Research finds that the composition prepared from the water-soluble components such as graphene oxide, dicloran and triphenyltin hydroxide has remarkable synergistic interaction, has low application cost, is environmental friendly, has no drug resistance, has high utilization potentiality in prevention and control of sclerotiniose, solves the problem of negative effectsto environments in long-term use of chemical pesticides, has the advantages of being green, environmental-friendly, free of pollution, long in service life, and accordingly has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of pesticides. More specifically, it relates to a graphene pesticide preparation for preventing and treating sclerotinia. Background technique [0002] Sclerotinia pathogenic fungi generally only attack mature or declining plant organs, and quickly cause plant tissue necrosis after invasion. Bacteria exhibit strict parasitic specialization or selectivity to plant organs. Typical symptoms are rotten stems, fruits, inflorescences, etc., and sometimes necrotic spots on leaves. Bacteria exhibit strict parasitic specialization or selectivity to plant organs. The ascospores of this type of fungus have a strong radiation ability, and the conidia are easy to disperse and are mainly spread by airflow. Sclerotinia is one of the main diseases that harm Danshen. The base of the stem, buds and rhizomes of the affected plants gradually rot and turn brown, and there are black rat feces-like sclerotia and white myceliu...
