Abstract
The invention relates to a wax gourd sclerotinia preventing and treating method and belongs to the agricultural technological field. Foliage spray is performed for one to three times with compound preparations which are composed of procymidone and carbendazim every seven to fifteen days. The prevention and treatment effect can be improved, wax gourd sclerotinia can be effectively prevented and treated, the dosage of effective components is reduced, cost in using preparations is reduced and environmental pollution is relieved.
Description
Technical field
The present invention relates to a kind of method of preventing and treating the wax gourd stalk break, belong to agricultural technology field.
Background technology
The wax gourd stalk break mainly cause harm fruit and stem climing.Fruit is caught an illness many in residual flower section, first be water soaking mode and rot, after grow white hypha, mycelia is entangled with into the black sclerotium.Sclerotium is survived the winter or is got over the summer on the carriers such as soil, seed.During condition maturity, sclerotium enters the field propagation thereupon and infects.This disease belongs to conidium aeroborne disease type, is characterized in that the conidium passed with gas, from parasitic flower and the intrusion of old and feeble blade, contacts and infects with healthy tree with conidium.After intrusion, grow white hypha, start to endanger column cap or young melon.The male flower that carries disease germs in field drops on strong leaf or stem and contacts through mycelia, easily causes morbidity, and carries out superinfection by this way, until worsening condition forms again sclerotium and falls into soil or sneak between seed and survive the winter or get over the summer with kind of a strain.Plant year after year Curcurbitaceae, Solanaceae and brassicaceous vegetable field, impeded drainage low-lying land or nitrogen fertilizer application or frostbite, freeze injury condition issue seriously ill partially.Take improve temperature bionomic control as main, be aided with chemical control.Procymidone is the novel systemic bactericide, has the effect of protection and treatment concurrently, and under the low temperature and high relative humidity condition, result of use is obvious, and the prophylactic treatment stalk break is had to comparatively significantly effect.But in production, the single medicament of long-term use, easily produce resistance, difficulty of prevention and cure increases gradually.
At present, not yet by the complex preparation formed with procymidone and carbendazim, be used for preventing and treating the correlative study document announcement of wax gourd stalk break.
Summary of the invention
The objective of the invention is the above-mentioned deficiency for prior art, a kind of method of preventing and treating the wax gourd stalk break is provided, be conducive to the disease-resistant high yield of wax gourd, increase economic efficiency.
The method of preventing and treating of wax gourd stalk break, on existing chemical control basis, the complex preparation that foliage-spray is comprised of procymidone and carbendazim 1 ~ 3 time, spray once in every 7 ~ 15 days.
Wherein, each active ingredient mass content of described complex preparation is: procymidone 55 ~ 70%, carbendazim 30 ~ 45%.Complex preparation can not mix use with alkaline agricultural chemicals or material.
The method of control wax gourd stalk break provided by the present invention has the following advantages:
1, raw material of the present invention is bought conveniently, and using method is simple.The raw material procymidone that formulated is required and carbendazim are easily purchases agricultural material product.
2, the present invention is better than single dose to wax gourd stalk break control efficiency.And the two is used in conjunction with and is difficult for causing poisoning, cost is lower than single procymidone.Therefore, the present invention has boundless application prospect.
Embodiment
Further illustrate the present invention below in conjunction with embodiment, but the scope of protection of present invention is not limited to following embodiment.
Embodiment 1: the test of control property, experimental cultivar is spring early No. 1.
During morbidity, use, each active ingredient mass content of complex preparation of the present invention is: 50% procymidone wettable powder 80 grams, 50% carbendazim wettable powder 20 grams, the two makes complex preparation after mixing, during use, 600 times of foliage-sprays of dilute with water 3 times, spray once in every 10 days, with same spraying method, sprays 50% procymidone wettable powder in contrast.According to investigation result, the control rate of 50% procymidone wettable powder is 78.8%, and preparation control rate of the present invention reaches 93.2%.
Embodiment 2: preventive trial, experimental cultivar is spring early No. 1.
There is the morbidity history in this canopy past, but test not yet morbidity then.Each active ingredient mass content of complex preparation of the present invention is: 50% procymidone wettable powder 70 grams, carbendazim 30 grams, the two makes complex preparation after mixing, during use, 800 times of foliage-sprays of dilute with water 3 times, within every 15 days, spray once, with same spraying method, spray 50% procymidone wettable powder in contrast.According to investigation result, the prevention incidence of disease of 50% procymidone wettable powder is 18.1%, and it is only 3.6% that preparation of the present invention sprays district's incidence of disease.
Claims (4)
1. a method of preventing and treating the wax gourd stalk break, is characterized in that, each active ingredient mass content of described complex preparation is: procymidone 55 ~ 70%, carbendazim 30 ~ 45%.
2. the method for control wax gourd stalk break according to claim 1, is characterized in that the complex preparation that foliage-spray is comprised of procymidone and carbendazim 1 ~ 3 time sprays once in every 7 ~ 15 days.
3. the method for control wax gourd stalk break according to claim 1 and 2, is characterized in that, described procymidone, carbendazim are wetting powder.
4. according to the method for the described control of claim 1 ~ 3 wax gourd stalk break, it is characterized in that, described complex preparation can not mix use with alkaline agricultural chemicals or material.
