Abstract
The invention relates to a pesticidal composition containing choline chloride. The pesticidal composition contains an active ingredient A and an active ingredient B, wherein the active ingredient A is choline chloride, and the active ingredient B is selected from any of the following compounds: sodium nitrophenolate and potassium nitrophenolate. The pesticidal composition is mainly used for increasing the chlorophyll content of plants, keeping the plants green and preventing the plants from aging, promoting root system development, promoting the real fertilizer absorption of crops, assisting the good growth of inferior parts of the crops, enhancing the water and fertilizer absorption of the plants and adjusting the balance of body water of the plants, thereby improving the drought resistance and cold resistance of the plants; and meanwhile, the composition disclosed by the invention has a synergistic effect on a variety of pests which endanger agricultural production, so that the dosage of pesticides is reduced, the residual quantity of the pesticides on crops is reduced, the environmental pollution is alleviated, the composition is safe to human and livestock, the environmental compatibility is good, and the drug resistance for the pests is difficult to generate.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of composition pesticide crops of chloride containing choline.
Technical background
Choline Chloride (cholinechloride): the key enzyme of activation photosynthesis of plant, the i.e. ATP-enzyme of photoreaction and the RUBP-carboxylase of dark reaction and glycerol-3-phosphate, impel plant absorption luminous energy and utilize luminous energy, fixing and assimilation CO2 better, improve photosynthetic rate, increase plant carbohydrates, protein and chlorophyll content.
Compound sodium nitrophenolate (sodiumnitrophenolate): be mono-nitration guaiacol sodium salt plant cell activating agent.Energy rapid permeability, in plant corpus, to promote that the protoplasm of cell flows, is accelerated plant rooting speed, is all had to developmental stage such as plant rooting, growth, reproduction and results the facilitation that degree is different.Especially for the promotion of the elongation of pollen tube, help the effect of fertilization particularly evident.Can be used for Promoting plant growth growth, early flowering, breaking dormancy, stratification, prevent fruit drop, improve the aspects such as the quality of plant product.This product can process by modes such as foliage spray, seed soaking, seedbed perfusion and bud spreadings.Because they are different from plant hormone, plant seeding start to results between any period, all can use.
Potassium para-nitrophenate (potassiumnitrophenolate): foliage-spray can promptly permeate in plant corpus, strengthen photosynthesis, accelerate cell division, promote Nutrient Absorption, thus accelerate rooting rate, breaking dormancy, prevent fruit drop, Promoting plant growth, can be used in cereal crops, economic crops, vegetables, fruit tree and flowers and other crops.
But in the real process of agricultural production, the problem that pest control the most easily produces is the generation of pest resistance to insecticide.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect clearly, very high composite just less of co-toxicity coefficient.For target plant, plant growth regulator is the non-nutritive chemical substance of external source, usually can conduct to site of action in plant corpus, just can promote or suppress some link of its life process with very low concentration, makes it the needs development to meeting the mankind.Every plant growth regulators has specific purposes, and application technology requires quite strict, only could produce specific effect to target plant under specific application conditions (comprising extraneous factor).Often change concentration and will obtain contrary result, such as, have facilitation at low concentrations, then become inhibitory action in higher concentrations.Active components A is different from the active component B mechanism of action, and mutually composite have good synergistic effect within the specific limits.And about Choline Chloride and the binary built from compound sodium nitrophenolate, potassium para-nitrophenate, there is not yet relevant report at home and abroad at present.
