Description
Technical field
The present invention relates to a kind of herbicide, be specifically related to a kind of herbicide preventing and kill off Semen Cuscutae.
Background technology
Semen Cuscutae is the pernicious parasitic seed plant of Convolvulaceae semen cuscatue spp, main parasitic dicotyledon, has that generation region is wide, spread rapidly, harm is serious, be difficult to features such as preventing and kill off.After Semen Cuscutae germination is unearthed, once running into host, its root is the most withered, it is adsorbed on plant with the climing winding of stem, blade is degenerated, and loses photosynthesis, obtains self required moisture and nutrition in pin main body, grow rapid and in great numbers, often result in host plant malnutrition, grow suppressed, show as yellowing leaf, branch wilting, rate of blossoming and bearing fruit reduction etc., time serious, plant is the most dead, causes huge economic loss.
Preventing and kill off Semen Cuscutae typically to carry out three periods, one is seed stage, and two is Seedling Stage, and three is the rattan phase.
At seed stage, i.e. before Semen Cuscutae germination, spray bud pre-treatment herbicide prometryn, Acetochlor etc., primary source of infection can be substantially reduced, but owing to Semen Cuscutae seed amount is big, survival time is long, can survive for many years in soil, and distribution and germinating time are difficult to grasp, covering plus plant, medicinal liquid is difficult to spray thoughtfully, it is impossible to form the medicine film layer closing ground, so being difficult to play the bud pre-treatment herbicide inhibitory action to Semen Cuscutae seed.
At Seedling Stage, after i.e. Semen Cuscutae seed is unearthed, seedling can independent growths about 10 days, covering due to plant, often being difficult to be found, medicinal liquid is the most difficult to be sprayed onto on very thin Semen Cuscutae seedling, adds that the drug effect of herbicide typically the most gradually to manifest, so spraying medicine at Seedling Stage, it is difficult to determine whether herbicide has effect.
In the rattan phase, after i.e. Semen Cuscutae is wrapped in plant, consume moisture and the nutrition of host, needed for meeting the growth of self, its rattan is flourishing and trophophase was up to 4 ~ 5 months, it is easy to identifies, now prevents and kill off, can accomplish with a definite target in view, with seeing with removing, so the rattan phase is the best period preventing and kill off Semen Cuscutae.
At the trophophase of Semen Cuscutae rattan, prevent and kill off frequently with two kinds of methods:
Manually pull out method.Owing to Semen Cuscutae is closely coupled with host plant by haustorium, manually pulls out and waste time and energy, be difficult to thoroughly remove, and the residual segment of Semen Cuscutae is when condition is suitable, again can continued growth, form new stem climing, then secondary parasite, so that repeatedly pull out.
Stem and leaf processes the anti-division of herbicide.Spray stem and leaf and process herbicide, easy and simple to handle, instant effect, but alternative herbicide kind is rare.The Shandong often mentioned in document protects No. one, has started the beginning of Chinese microbe herbicide, and it, to people and animals' nonhazardous, easily grows, and is a kind of effective biological weed killer, but owing to this product storage life is short, and do not carry out commercial production；Use " glyphosate " prevents and treats Semen Cuscutae to have document to report, but this medicine is steriland herbicide, does not has selectivity being both between the host of dicotyledon and Semen Cuscutae, and while Semen Cuscutae is prevented and kill off, host plant also can produce obvious poisoning；" butralin " has inhibitory action to the rattan of Semen Cuscutae separately to have document to report, but in practice, it has been found that preventive effect is unsatisfactory, the only tender point to Semen Cuscutae has slight inhibitory action, and concentration increases, and host will be produced poisoning.
Chinese patent CN103098798A discloses a kind of herbicide for Soybean Field, it uses bud pre-treatment Determination of Herbicide Acetochlor that Semen Cuscutae seed is played inhibitory action, Semen Cuscutae seedling is worked by fomesafen, stem and leaf processes herbicide haloxyfop-r-methyl and Quizalotop-ethyl is high selectivity herbicide, described haloxyfop-r-methyl and Quizalotop-ethyl have chosen and well known to a person skilled in the art conventional amount used condition, only monocotyledonous stem and leaf there is is inhibitory action, dicotyledon Semen Cuscutae is prevented and kill off almost without effect.
