Description
Technical field
The present invention relates to technical field of pesticide, particularly a kind of Pesticidal combination and application thereof, preparation.
Background technology
Paddy rice originates in Tropical Asian, after China widely plants, propagates into gradually all over the world.Paddy rice institute knot reality and paddy, claim rice, scented rice, rice after paddy shells.Nearly half population is in the world all food with rice.Paddy rice, except edible, can also be made wine, refine sugar and make the raw material of industry, rice husk, rice straw, can as feed.
In Rice Cropping process, common insect mainly comprises homoptera pest (typical insect has rice fulgorid, Bemisia tabaci etc.) and lepidoptera pest (typical insect has striped rice borer, rice leaf roller etc.) etc.Wherein, rice fulgorid inhales plant juice to cause harm the crops such as paddy rice to sting, and make its growth retardation, time serious, rice clump is agglomerating withered, the dead stalk lodging in even full field; Striped rice borer is that China paddy rice endangers one of Occurrence the most serious, and main harm is for cause withered sheath, withered heart seedling in rice plant of tillering stage, and cause in the fringe phase and hinder strain and dead ears, cause the underproduction, the general time underproduction 3% ~ 5%, time serious, the underproduction is more than 3 one-tenth.Based on the harm of these insects to crops, be the top priority in China's agricultural production for the monitoring of these insects, early warning and control all the time.
At present, the method for pest control is mainly chemical control.Chemical control is also called pesticide control, is to carry out prevention and elimination of disease and pests by the toxicity of chemical agent, has the advantages such as efficient, quick-acting, easy to use, economic benefit is high, and it is the most frequently used method of plant protection, is also important measures in integrated control.
But along with the continuity of chemical control, the increase of Pesticide use amount and not scientifical use agricultural chemicals, pest resistance is day by day serious, the pest species producing resistance is on the increase, particularly to the Lepidoptera class pest that agricultural production is caused harm serious, resistance level is higher, resistance development speed is relatively very fast, and the resistance problem of pest becomes a global problem.Meanwhile, the use agricultural chemicals of high strength, causes Practice for Pesticide Residue in Agricultural Products to exceed standard, environmental pollution and the increase of peasant's drug cost etc., is unfavorable for agricultural sustainable development.Therefore, efficient, the low toxicity of research and development, environmental protection, insecticidal spectrum is wide, the lasting period is long pesticide have positive effect to agricultural sustainable development.

Test and carry out in a peasant household rice field in Xishan, Jiangsu, each group process repeats for 4 times, and processing area is 30m
2.This tests rice varieties used is No. 7, normal agriculture round-grained rice, and its ripening rate is about 91.3%.Experimental group uses the fertile preparation of slow releasing medicinal that embodiment 2 to embodiment 8 prepares respectively, and insecticide-applying way is when rice transplanting, is spread by fertile for slow releasing medicinal preparation in being manured into soil; Control group use respectively 1% Diacloden sustained-release granular formulation, 0.5% diazinon granule, 45% composite fertilizer, the fertilization mode of each control group is identical with experimental group fertilization mode.After paddy rice maturation, paddy rice is collected in grouping, adds up each group rice yield, investigates the economic scene of each group paddy field.The amount of application of the test sample of each group, and each group rice yield is in table 3.
The amount of application of the test sample of each group of table 3 and wheat yield statistics
From table 3, experimental result is known, and when effective ingredient consumption is suitable, compared with control group, the slow releasing medicinal fertilizer granular formulation effect of increasing production that the embodiment of the present invention 2 to embodiment 8 prepares is more obvious, significant difference (P < 0.05).Illustrate that the fertile preparation of slow releasing medicinal that the embodiment of the present invention 2 to embodiment 8 prepares can significantly improve the output of wheat.
The slow releasing medicinal fertilizer granular formulation that investigation embodiment 9,10 prepares is on the impact of wheat yield, the result of the slow releasing medicinal fertilizer granular formulation of result and embodiment 2 ~ 8 is close, illustrates that the slow releasing medicinal fertilizer granular formulation of the embodiment of the present invention 9,10 can significantly improve the output of wheat.
In sum, the fertile preparation of slow releasing medicinal provided by the invention, have active high, good drug efficacy, fertilizer efficiency are remarkable, possess medicine, fertile double effects, the effect of desinsection, getting fat can be given full play to, not easily produce the features such as resistance, and to crop safety, use easy, dosage is few, and effective drug duration is long, has effectively saved the Productive statistics of peasant, improve crop yield, have a wide range of applications in agricultural production.
