The application discloses a snail-preventing and controlling medicine-fertilizer granule and a preparation method thereof. The snail-preventing and controlling medicine-fertilizer granule comprises ferrous lactate, an attractant, a slow-release material, an additive and the rest of tea dregs. The ferrous lactate and the tea dregs are combined to prevent and control snails, and a synergistic effect is achieved. The problems of water pollution caused by tetraacetaldehyde, the problem of heavy metal enrichment caused by the mixture of EDTA iron sodium and normal phosphoric acid iron, the problem of short medicine effect duration caused by the tea dregs impregnated water solution, and the problem of slow effect and poor prevention and control effect caused by dry tea dregs scattering are overcome. The snail-preventing and controlling medicine-fertilizer granule has the characteristics of super-long prevention and control time and good snail prevention and control effect. The ferrous lactate can provide trace element iron for vegetation in soil. After the tea dregs are fermented in soil, the tea dregs have the effects of improving soil and promoting crop growth, and have the functions of both a fertilizer and a biological pesticide.

The formulation comprises particles of a first active compound having a median particle size of 0.1 to 20 microns as measured by light scattering. The formulation may also include an emulsifier, a second dispersant, and / or an agriculturally active compound (e.g., an acaricide, antibacterial agent, fungicide, herbicide, insecticide, molluscicide, or nematicide, or a combination thereof). Also disclosed are agricultural compositions comprising the formulation and methods of using the same.

The invention relates to the field of agricultural chemistry, in particular to a binary compound insecticidal composition containing niclosamide and metaldehyde, which is used for solving the problems that the traditional single-component insecticide can cause drug resistance of pests after being used for a long time, so that the control effect is reduced, certain limitation exists, and the use cost is low. The effect is not obvious when facing other types of pests, so that the negative influence on the environment is caused; according to the insecticidal composition, the niclosamide and the metaldehyde are compounded to form dual attacks, the dual attacks act on a nervous system and a respiratory system respectively, the lethal speed is remarkably increased, binary compounding of the niclosamide and the metaldehyde has a remarkable synergistic interaction effect, the defect that a single component is insufficient in insecticidal effect on pests under special environmental conditions is overcome, and the insecticidal effect is good. The control effect is improved, the dosage is reduced, and the development of drug resistance is delayed.

The invention discloses a rice field alien species ampullaria gigas ecological prevention and control method which comprises the following steps: generating a paddy-upland rotation and intelligent water layer regulation and control instruction according to rice field multi-source information, destroying an ampullaria gigas inhabiting environment according to the instruction, and obtaining a first intermediate state; generating a multi-stage physical interception and sinking snail inactivation instruction according to the first intermediate state, and collecting and inactivating a migrated snail body according to the instruction to obtain a second intermediate state; generating a composite biological barrier and targeted trapping and killing instruction according to the second intermediate state, and attracting and killing ampullaria gigas in a ridge trapping belt according to the instruction to obtain a third intermediate state; and generating a central control closed-loop instruction according to the third intermediate state, returning the data of each stage according to the instruction, and dynamically optimizing the next round of regulation to realize continuous prevention and control. The method can realize zero use of the chemical molluscicide, and has the application prospects of economy, high efficiency, eco-friendliness and sustainable popularization.

This invention provides a plant-derived and microbial-derived pesticide composition for attracting and killing golden apple snails, its preparation method, and its application, belonging to the field of pesticide technology. The pesticide composition of this invention includes: duckweed extract, betaine, plant-derived components, microbial-derived components, and excipients; the plant-derived components consist of catnip extract, pokeweed extract, and areca nut extract, and the microbial-derived component is microencapsulated Bacillus thuringiensis. This invention utilizes the combination of duckweed extract and betaine to actively attract golden apple snails for feeding; the ternary combination of plant-derived components synergistically destroys the snail's mucous membrane and interferes with its physiological metabolism, rapidly killing the golden apple snail; the microbial-derived component colonizes in the snail's intestines, releasing molluscicides, forming an internal and external snail-killing mechanism. Tests show that the pesticide composition of this invention has high safety for zebrafish and significant killing effects on juvenile and adult golden apple snails, exhibiting strong attraction, thorough snail killing, and environmental friendliness, making it suitable for green control of golden apple snails in aquaculture waters.
