Embodiment 1

[0048] Example 1. Preparation of Lycopodium sporozoites (LCSC)

[0049]Weigh 5 g of lycopodium spore powder into 50 mL of acetone, stir magnetically for 4 hours at 50° C. (rotation speed is 500 rpm), and filter with suction to obtain delipidated lycopodium spore powder. Add 50 mL of 5M phosphoric acid solution to remove the genetic material in the inner cavity, stir magnetically for 4 hours at 80 °C (rotation speed is 500 rpm), filter with suction, wash with water 3 times, and dry the filter cake in a 60 °C oven to constant weight, that is, lycopodium spores are obtained. Pollen wall. Its appearance is as figure 1 shown.

Embodiment 2

[0050] Example 2. Preparation of fluazinam microcapsules (FLU@LCSC) based on lycopodium sporozoites

[0051] Weigh 10 g of the lycopodium spore powder material prepared in Example 1, add it to 50 mL of fluazimidine acetone solution (fluazimuth concentration is 0.2 g / mL), and magnetically stir at room temperature for 24 hours (rotation speed is 500 rpm). Then rotary-evaporated to dryness, transferred to a Buchner funnel for suction filtration, washed three times with acetone and twice with water. The filter cake was pre-frozen in a -40 ℃ refrigerator for 4 hours, and then freeze-dried for 12 hours to obtain fluazinam microcapsules (FLU@LCSC) based on lycopodium sporozoites. Its appearance is as figure 2 shown.

Embodiment 3

[0052] Example 3. Preparation of fluazinam microcapsules (FLU@LC) based on natural lycopodium spores

[0053] 10 g of natural Lycopodium spore powder was weighed and added to 50 mL of fluazinadine acetone solution (fluazimuth concentration was 0.2 g / mL), and the mixture was magnetically stirred at room temperature for 24 h (rotation speed was 500 rpm). Then rotary-evaporated to dryness, transferred to a Buchner funnel for suction filtration, washed three times with acetone and twice with water. The filter cake was pre-frozen in a -40°C refrigerator for 4 hours, and then freeze-dried for 12 hours to obtain fluazinam microcapsules (FLU@LC) based on natural lycopodium spores. Its appearance is as image 3 shown.

Abstract

The invention discloses a pesticide carrier based on plant sporopollen and application thereof. The pesticide carrier based on the plant sporopollen is untreated plant spores or pollen or plant sporopollen derivatives. According to the invention, the plant sporopollen is introduced into a pesticide controlled release system as a pesticide carrier for the first time, a novel green and efficient pesticide carrier is developed, all the used raw materials are natural components, are wide in source, good in biocompatibility, non-toxic and pollution-free, and have the advantages of simple preparation method, mild reaction conditions and the like.

Description

technical field [0001] The invention belongs to the field of pesticide formulations, in particular to a pesticide carrier based on plant pollen and its application. Background technique [0002] Pesticide controlled release formulations coat the active ingredients of pesticides by physical, chemical or physicochemical means to protect the active ingredients from adverse environmental effects and achieve slow or controlled release, which can reduce the number of applications and dosage, and improve the utilization rate of pesticides , is an efficient, safe and economical new formulation of pesticides. Carrier materials are the core components of pesticide controlled release agents. In addition to basic physical and chemical properties, the source, toxicity, biodegradability and environmental safety of carrier materials are also important factors that affect their comprehensive performance and application prospects. However, the existing pesticide carrier materials are mainly...
