2and multiple flavonoids O), belonging to biological category, is a kind of botanical pesticide of environmental protection, has desinsection, several functions is adjusted in sterilization, growth.
Insecticidal action: have strong action of contace poison to vegetables cabbage caterpillar, vegetable aphid, melon aphid, snout moth's larva, ladybug, beet armyworm, striped flea-beetle, diamond-back moth low instar larvae, Lan Yee, fragrant-flowered garlic maggot, yellow palm moth and elm fleautiauxia armata; All more than 90% is reached to the control efficiency of black peach aphid, radish aphid, Schizaphis piricola, wheat aphid; To the black poison moth of tea, caterpillar, boat type caterpillar, slug moth, chi Qu, two spotted spider mite lecanium, chafer, stinkbug etc. are admired in the sky on fruit tree, and on cereal crops, the various pests preventive effect such as mythimna separata, wheat midge and locust is obvious.Matrine have insect tag, stomach toxicity, interior suction, food refusal, sterilization, interference decortication, paralysis central nervous system, polypide protein coagulation, polypide pore block, the biologically actives such as suffocate pests is dead.
Bactericidal action: have obvious inhibitory action to wheat scab, Pyricularia oryzae Cav bacterium, apple anthracnose, the growth of graw mold of tomato mycelia and germ spore germination; Certain inhibitory action is had to lawn pathogenic bacteria such as Rhizoctonia solani, foot stalk skin umbrella, the rotten enzyme of the special Bo Lishi of model, the raw rotten enzyme of standing grain, the rotten enzymes of melon and fruit; Inhibited to the downy mildew on vegetables, powdery mildew, gray mold and epidemic disease.After spraying matrine, the growth of cotton-wilt fusarium mycelia stops completely.The fungicide active ingredient of matrine can suppress the biosynthesis of thalline, can affect mycelial biological oxidation process again, and fungicidal spectrum is wider.
Plant growth promote function: as spray process its cotyledon fresh weight of cucumber and dry weight and fresh weight of plant seedlings obviously increase, the rooting effect of cucumber cotyledons petiole base can also be promoted.After matrine process wheat flag leaf, processed group blade sugar content is about 1.4 times of contrast, apparently higher than contrast, has important function to the growth of fringe and the accumulation of seed dry matter.The substance such as amino acids, fatty acid in addition in matrine extract fast absorb by plant, supplement plant nutrient, strengthen stress resistance of plant; In shrubby sophora extract, oside compound has certain regulating action to plant.
The domestic and international application technology to shrubby sophora extract and formulation technology have carried out extensive research, the development and application report of the kinds such as existing missible oil (EC), soluble powder (SP), aqua (SL), shrubby sophora extract is due to its using dosage extremely low (every mu only needs active ingredient matrine 0.15g), generally be processed into 0.1 ~ 3% content formulation, as being processed into 0.3% missible oil, its organic solvent such as dimethylbenzene, solvent naphtha content reach more than 80%, and equal entered environment, seriously polluted in use; And it is too strong due to hygroscopicity to be processed into 0.1% soluble powder, in packing, use, have dust from flying, these formulations can only be used for spraying, and availability is extremely low, thus affect the performance of drug effect.
Brassin lactones have take root, growth promoting effects, carry seedling, strong sprout, keep a full stand of seedings, yellowtop leaf turns green, promote fertilization, flower and fruit protecting, promotion Fruit are precocious, alleviate that disease is alleviated poisoning, coordinated nutrient balance, drought resisting is cold-resistant, reduce and make the multi-functional such as residue of pesticide in object, enhancing crop anti-adversity.To the dead seedling caused because of reasons such as continuous cropping, disease, poisoning, freeze injuries, rotten, vertical withered, phenomenon of dampinging off first aid effect remarkable, use and namely obviously take effect for 12 ~ 24 hours, recover life rapidly.Be applicable to cereal crops, economic crops, vegetables and fruit etc., growth promoting effects, increase yield.
Brassin lactones is the one that in steroidal compounds, biologically active is higher, and they are extensively present in plant corpus.In growth and development of plants each stage, both can promote to nourish and grow, be conducive to amphigamy again.The concentration denier that it works is efficient plant growth regulator, under very low concentrations, can increase the Vegetative growth of plant significantly and promote amphigamy.Its some physiological actions performance has some feature of growth hormone, gibberellin, the basic element of cell division:
1, promote cell division, promote Fruit.There is obvious facilitation to the division of cell, have facilitation to the cross growth of organ and longitudinal growth, thus play swollen megalocarpous effect;
2, Delaying Leaf-Senescence, it is long to protect the green time, strengthens Chlorophyll synthesis, improves photosynthesis, impels leaf look to deepen to turn green;
3, break apical dominance, promote sprouting of lateral bud, thoroughly can lead the differentiation of bud, promotion side shoot generates, and increases branch number, increases and spend number, improves becoming pregnant property of pollen, thus increases fruit number raising output;
4, improve crop quality, improve commodity.Induced parthenocarpy, stimulates ovary increasing, prevents fruit drop, promotes protein synthesis, improves sugar content etc.
Domestic brassin single dose has 0.01% missible oil, 0.01% pulvis, 0.0075% aqua, 0.004% missible oil.
The present invention has positive meaning to the keeping a full stand of seedings of crops, strong sprout, raising output.
Summary of the invention
The object of the invention is to overcome defect of the prior art, the characteristic for matrine, brassin lactones provides a kind of containing matrine, brassin lactones, the suspension seed-coating agent of process seed.This seed coat agent is the one water base property suspension seed-coating agent adopting corresponding suspending agent processing technology to be prepared from, and can be used for the crop pests such as paddy rice, wheat, corn, soybean, cotton, peanut, beet, sunflower, controlling disease, strong sprout, promotion adjustment growth.
