Description
Technical field
The invention belongs to biological pesticide technical field, relate to a kind of medicine based on herbs preventing and treating custard squash pythium rot particularly.
Background technology
Custard squash pythium rot belongs to fungal disease.Germ survives the winter in matrix, invades plant, propagate by rainwater, irrigation or bookkeeping etc. by stem, leaf and fruit epidermis.Most susceptible disease under the condition of, high humidity low in substrate temperature.The harm of custard squash pythium rot leaf, stem and fruit.Sick leaf and stem have the dark green spot of circular water soaking mode, present soft rot time moist.Sick fruit has oval dirty-green water logging spot, and time dry, scab becomes brown, depression, and has putrefactive phenomenon, the mould layer of raw adularescent; Time moist, whole fruit presents brown and rots, and surface is covered with white mould.Existing conventional control method: (1) cultural control, uses the compost of ferment bacterium retting or rotten hot fertilizer, adopts high bedding cultivation, melon can be paved after knot melon, prevent humidity from catching an illness, avoid broad irrigation, timely draining after heavy rain, suitable Potassium, finds that disease melon is removed in time; (2) biological control, " 5406 " No. three agent 600 times of liquid are sprayed in melon patch, increase antibiotic bacteria in soil, suppress growth of pathogenic bacteria, thus reach the (3) chemical control of diseases prevention object, their early stage, with 14% network ammonia copper aqua, 300 times of liquid, the 500 times of liquid sprayings of 12% copper rosinate missible oil, every spray in 10 days 1 time, connect spray 2 ~ 3 times, or with 72% cymoxanil mancozeb wettable powder, 800 times of liquid, or the clever wetting powder of 50% bacteriolyze 800 times of liquid, or 72.2% generally makes every effort to overcome aqua 800 times of liquid, or the 800 ~ l000 times of liquid spraying of 10% Pola peace wetting powder.
Patent of invention CN104286058A discloses biopesticide bactericide that a kind of Chinese herbal medicine makes and uses thereof, and this bactericide is made up of the component of following mass percentage: garlic extract 45%-55%, cordate houttuynia extract 15%-25%, kitchen garden extract 10%-20%, tarragon ginkgo sweet wormwood extract 8%-15%, Cosan 3%-5%.Patent of invention CN103651353A discloses a kind of containing zoxamide and the composite bactericidal composition of metalaxyl, for preventing and treating pythium rot.Patent of invention CN104012529A provides a kind of bactericide, comprises protectant and therapeutic agent; Described protectant comprises Da Kening, tpn, large raw, spray gram, safe and sound life, lime sulfur, iprodione, can kill, Cupravit; Described therapeutic agent comprises: Hymexazol-matulaxyl, dislike mould spirit, agricultural streptavidin, blue or green withered spirit, kasugarnycin, pungent bacterium amine.Above-mentioned patent products obtained therefrom is pure Chinese medicine or pure biochemical preparation, chemical agent plays a significant role in crop pest control, but, due to chemical agent Long-Time Service, cause most area damage by disease and insect fastness frequency more than 50%, resistance level is up to more than ten thousand times, and single use chemical agent loses preventive effect completely, and, along with resistant strain constantly strengthens, spraying times increases year by year, and formulation rate is also doubled and redoubled, and brings immense pressure to control and surrounding environment., its drawback also becomes increasingly conspicuous, as medicament residue, environmental pollution and pest rampant again etc.; Although and Chinese medicine preparation has nontoxic, low-residual, pollution-free, without advantages such as pesticide resistance, effect is unsatisfactory again.
