Embodiment 1

[0035] Weigh 20 kilograms of pineapple rhizomes, store them at minus 20°C for 36 hours, then break them into powder, add 20 kilograms of water, mix well, add 20 grams of cellulose degrading enzymes, adjust the pH value to 4.0-5.0 with acetic acid, mix at 20 Place it under the condition of ℃ for 60 hours, separate and filter, and take 25 kg of the filtrate to be the cellulose degrading enzyme hydrolyzate (hereinafter referred to as component 1). In addition, 40 kg of chitin was weighed and mixed with 3 kg of acetic acid to form a chitin solution (hereinafter referred to as component 2). Mix component 1 and component 2, add 1 kg of sodium benzoate, 1 kg of sodium citrate, 1 kg of sodium hydroxide, 3 kg of diatomaceous earth, add appropriate amount of water to make up to 100 kg. Finally filtered and bottled. The finished product is a colorless transparent viscous liquid.

[0036] When used 5-7 days earlier than ordinary pesticides, it is diluted 500 times and sprayed on the sur...
