Promote the double effective fatty acid preparation of plant growing and protective plant
One. technical field
The present invention relates to the new purposes of compound aspect plant protection and promotion plant growing, belong to chemistry and agricultural technology field, relate to chemistry, agronomy and biochemistry etc.
Two. technical background
Along with the development of chemical industry and the expansion of the agrochemical fertilizer scope of application, the quantity of chemical pesticide and kind are all in continuous increase, and World chemical agricultural chemicals gross yield (in active ingredient) is above 3,000,000 tons now.Because using in a large number for a long time of chemical pesticide and chemical fertilizer brought serious environmental to pollute and the drug-fast continuous increase of sick worm.Many countries have all dropped into substantial contribution and have researched and developed the novel formulation that can substitute or reduce chemical pesticide and chemical fertilizer, to keep the sustainable development of agricultural production.
Environmental pollution and residue of pesticide that agriculture chemical causes are even more serious in China.There are 1.2 hundred million hectares of arable lands in China, and the total amount of application of chemical pesticide reaches 131.2 ten thousand tons, uses 931.3 grams for average every mu, and vegetables and melon and fruit more reach 6.67 kilograms/mu.The fertilizer amount of China has then accounted for 1/3 of global consumption, has brought serious rivers and lakes and underground water eutrophication pollution thus.Causing the output because the grower covets of using in a large number on the one hand of China's fertilizer and pesticide, is owing to lack the use that can effectively reduce fertilizer and agricultural chemicals but the method and the product that can guarantee crop yield on the other hand.
The fatty acid that is present in occurring in nature in a large number of discovering in early stage has certain bacterium and Fungicidally active extremely, and the n-nonanoic acid of high concentration has very strong phytotoxicity also to be used as weed killer herbicide.S.D. people such as savart lattice has obtained good effect (CN1069391A) with direct antifungal in disease position and bacterium that fatty acid is administered to plant, the result of treatment of fatty acid by antifungal and bacterize plant disease emphasized in their research, just there is not an activity but the concentration of making statement fatty acid is very low, too highly then plant is damaged, and fatty acid and its salt or derivative do not have prophylactic activity to plant disease.In the experimental result that they provide, fatty acid and its salt or derivative are that therapeutic action is just played at the disease position that is applied directly to plant, and the minimal effective concentration that the salt of fatty acid and it or derivative are administered on the plant is 0.125%a.i. (1250 mg/litre), and concentration is low to moderate 0.063% o'clock used fatty acid or its salt or derivative and has not just controlled the effect of infection process.
The present invention relates to be used for the new purposes that plant pest is grown and prevented and treated to coordinate plant growth with the new compositions that known compound is made, by with the combination of inorganic acid or organic acid and mineral salt or organic salt, very the aliphatic acid composition of low concentration has promptly been obtained and has been promoted plant growing, increase the outstanding effect on the plant products, and the composition of this low concentration can also effectively prevent the various plants damage by disease and insect.Use chemical fertilizer in a large number and the pollution of agricultural chemicals in agricultural product and environment has very positive meaning for reducing.
