Description

Recompounded farm chemical for peanuts

The invention belongs to crop and use agricultural chemicals, particularly relate to a kind of be used for the peanut drought resisting, disease-resistant, the volume increase usefulness the Recompounded pesticide Recompounded farm chemical for peanuts.

Peanut is one of main oil crop of China, and it is the important source material of oil prodution industry, also is the necessity of daily life, and by product is again good feed and fertilizer.Therefore, countries in the world are very paid attention to the production of peanut, and cultivated area enlarges day by day.The most of province of China, Qu Douyou plantation, but mainly concentrate on the sand soil and the knob of arid and semi-arid lands, therefore arid is to influence peanut yield one big factor, and there is not desirable drought resisting medicine to execute at present,, the dry season often takes place again in the middle and lower reach of Yangtze River peanut growth lack of water is wilted often because of spring drought causes the disconnected ridge that is short of seedling in the north.Another factor that influences peanut yield is a disease, to bigger being stem rot, root-rot dead (being referred to as dead disease) causing and occurring in the peanut various leaf spots of growth middle and later periods of yield effect, only the annual peanut yield that just can make of leaf spot loses about 25%, existing several agricultural chemicals, as pcnb, Tuzet etc., but price height and effect are also undesirable, so the peasant presses for the novel agrochemical of a kind of not only drought resisting but also diseases prevention.

Purpose of the present invention just provides a kind of diseases prevention, drought resisting can promote the novel agrochemical of growing simultaneously again.

Its technical scheme is: the Recompounded pesticide Recompounded farm chemical for peanuts, form by fulvic acid, bactericide and various trace elements, and by weight, contain fulvic acid 40-60%, bactericide 30-50%, surplus is a trace element.

Above-mentioned bactericide is that carbendazim, tmtd, mancozeb, tpn, thiophanate methyl etc. are wherein a kind of;

Trace element is boron, manganese, molybdenum, they are that mode with compound adds, boron, manganese, molybdenum add with the form of borax, manganese sulphate, ammonium molybdate respectively, its shared percentage by weight in whole Recompounded pesticide Recompounded farm chemical for peanuts is respectively: borax 1-10%, manganese sulphate 1-3%, ammonium molybdate 3-5%.

Produce above-mentioned agricultural chemicals, only need each component proportioning is on request weighed up, require full mistake 80 orders of each component fineness, at normal temperatures and pressures, be finished product with twin-screw mixing procedure machine mixing.

Fulvic acid is a kind of weakly acidic natural high molecular substance, be that molecular weight is less in the humic acid, active function groups is more, can be directly water-soluble, easily by the component of plant absorbing, it has can dwindle the blade face stomatal aperture, reduce the moisture content transpiration, improve the root system vigor, increasing chlorophyll content, strengthen multiple advantages such as photosynthesis, is again a kind of good pesticide slow-release synergist simultaneously.It can promote root growth, strengthens the absorption of root system to the moisture content nutriment, regulates moisture content situation in the plant body, plays drought resistance function.It can promote photosynthesis and plant that trace elements absorbed is turned round again, simultaneously, makes by the activity that improves plant body endoperoxidase and to make the deposits yields premunition, and agriculture chemical compounding, under equal drug effect situation, can make pesticide dosage reduce 1/3rd, reduce cost, also reduced environmental pollution.The Recompounded pesticide Recompounded farm chemical for peanuts except that having above-mentioned advantage, also has good preventive effect to dead disease of peanut and leaf spot etc., simultaneously to the desirable influence that grown of plant.Owing to also added trace elements such as boron, manganese, molybdenum in the compound medicine, promoted the growth of peanut effectively, improved the ripening rate of peanut.

Recompounded farm chemical for peanuts can be used for seed dressing, seed soaking or foliage-spray.

Performance test: (Recompounded farm chemical for peanuts replaces with symbol PFA, and the test contrast replaces with B with pesticide carbendazim.）

(1) the PFA seed soaking is to preventing and treating the effect of dead disease

In the peanut in 5 years of continuous cropping ground randomized arrangement, triplicate, sub-district area half point manually causes earlier slightly mouldyly for planting experimentally before son is handled, then carry out seed treatment, soup seed soaking 24 hours and the seed dressing of agricultural chemicals B conventional amount used, three of seeds treated every cave program requests are write down the fate of emerging, the number of emerging, flowering stage, add up dead and calculate preventive effect, the result as shown in Table 1, the PFA seed soaking can not only be eliminated the surface of the seed bacterium, can also prevent the dip-dye of germ in the soil, and can promote that seed sprouting emerges, contrast and agricultural chemicals B routine are emerged soon the emergence rate height, to stem rot, dead the sick preventive effect that root-rot causes shows the superiority with the PFA seed dressing also up to 90%.

Table one: seed soaking is to peanut seed seeding stage dead sick preventive effect

Handle	The fate of emerging	Emergence rate %	Dead plant rate %	Preventive effect
					The PFA seed soaking	6	96.2	1.5	90.3
The conventional seed dressing of B	7	95	2.5	83.9
					CK	8	83.4	15.5	0

(2) PFA seed soaking influence that peanut is grown

Test is carried out on the seedbed, randomized arrangement, triplicate, 3 row districts, long 3 meters of row, 40 centimetres of line-spacings, 10 centimetres of spacing in the rows, trench digging single grain waved sowing, initial bloom stage investigation plant height, individual plant branch amount, root/shoot ratio, dry weight etc. have been observed the reaction to arid, and measure the chlorophyll content (mgdm of unit ^-2) and the net photosynthesis intensity (mgdm of unit ^-2-h), every sub-district 10 strains of taking a sample after emerging 20 days, select for use 2 compound leaves that fall of every strain to measure, the result as shown in Table 2, after the PFA seed soaking, promoted the seedlings root growth, main root is long, and lateral root is many, and root/shoot ratio improves 33.53% than CK, thereby strengthened absorbing capacity, improved the drought resistance of peanut moisture content.Behind June 30 insemination and emergence, the continuously arid no rain of weather before just spending, in the seedbed not under the water supply conditions, the seedling of PFA seed soaking can more normally grow, and the wilting phenomenon do not occur, and serious wilting has appearred in CK, though after water flowering stage, also can restore normal growth, but plant is little, and other every indexs of PFA seed soaking are also all apparently higher than CK, for seedling development has been established material base preferably.

The influence that table two PFA seed soaking is grown peanut

(3), PFA sprays the effect to control stem rot, root rot:

It experimental field is wheat Gansu Province program request peanut, the dispenser in latter stage of blooming, randomized arrangement triplicate, sub-district area are one minute, experimental cultivar is a white sand 1016, investigation morbidity radix was investigated once continuous observation three times every 7 days after the dispenser before the dispenser, observe its preventive effect and the longevity of residure, the result as shown in Table 3, the preventive effect and the longevity of residure all are higher than agricultural chemicals B routine, preventive effect improves 49.7% after 21 days.

The protection effect that table three PFA sprays

(4) field sprays the preventive effect of PFA to leaf spot

July 23 sprayed, and investigation in 18 days is to the control efficiency of leaf spot behind the medicine, and preventive effect is 56.3%, and the preventive effect of using than B prescription 46.1% improves 22.13%.

Table four PFA field sprays the preventive effect to leaf spot

(5) resisting drought, preventing disease of field demonstration and effect of increasing production

Here be that example is listed table five in Henan Province's result of the test

Table five PFA effect
