Abstract
The invention discloses a pesticide composition and application thereof in potato bud inhibition and fresh-keeping, wherein the pesticide composition comprises the following active components: the composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is sodium furoate, and the active ingredient B is 3-decene-2-ketone; can reduce the times of drug administration, improve the sprout inhibition effect, improve the starch content of the stored potatoes, reduce the rotting rate, improve the storage quality and solve the problems of pesticide residue and food safety caused by the traditional chemical pesticide.
Description
Technical Field
The invention relates to the technical field of pesticides, and particularly relates to a pesticide composition and application thereof in bud inhibition and fresh keeping of potatoes.
Background
The potato (with the scientific name of Solanum tuberosum) belongs to perennial herbaceous plants of the solanaceae, and tubers are edible and become five crops in the world together with wheat, corn, rice and sorghum. The potatoes have an obvious physiological dormancy period after being harvested, and the physiological dormancy period is generally 1-2 months. After the dormancy stage, the potatoes enter the sprouting stage, and the potato blocks become soft and wrinkled due to the fact that a large amount of nutrition and moisture are consumed for the growth of buds. Starch and protein stored inside the potato blocks are converted into sugar and amino acid, and a large amount of solanine is generated around eyes of buds, so that the edible value and the processing value of the potatoes are seriously influenced.
The existing bud inhibiting technology mainly comprises cellaring, seed soaking, application of a bud inhibitor and the like. When the cellar is stored, ventilation is ensured to reduce rotting, so that enough space is needed to realize the rotting reduction. The seed soaking with the medicament can make the potato seeds uniformly contact with the medicament, but the medicament needs to be dissolved in water because the seed soaking needs dilute solution of the medicament, and the optimal application concentration and the optimal seed soaking time need to be found during seed soaking, so that the seed soaking is not easy to master. And the seeds need to be spread out and dried after being soaked, and enough space is needed for realization. The research and application of our country in the bud inhibitor are relatively lagged, and the method mainly depends on the import of bud inhibitor products in foreign countries. The cynanchum wilfordii is also called as "yokudan", abbreviated as MH. The freshness-keeping agent also has a bud inhibition effect on potatoes, and is sprayed on the leaf surfaces of the potatoes in the field 2-4 weeks before the potatoes are harvested, so that the germination of the potatoes in the storage period can be inhibited. In general, the freshness agent can be transferred to the growing points of the potato blocks after about 2 weeks, so that the germination capacity of the potato blocks is lost, and the germination of the potatoes in the storage period is inhibited. When the fresh-keeping agent is used, the key is to spray the fresh-keeping agent in the potato block expansion period. However, in recent years, the use of the cynarin in food is forbidden in China due to the discovery that the cynarin has the potential safety hazard of carcinogenesis. The data of the food and agriculture organization/world health organization of the united nations show that the cynanchum has certain carcinogenic effect on human bodies and is forbidden by developed countries such as the United states, Japan, Australia and the like. Chlorpropham, CIPC for short. Is currently the most widely used potato sprout inhibitor in the world, with CIPC being commonly used in potato storage in almost all european countries, the united states, australia and a few developing countries. The fumigation has the best effect of inhibiting buds, and the aging period is more than 3 months. The CIPC can effectively inhibit the potato from sprouting at normal and low temperature, the sprouting speed is slowed down, and the sprouting inhibition rate reaches more than 85 percent. However, the inhibition of potato sprouting by CIPC is irreversible and therefore cannot be applied to seed potatoes. CIPC remains in potatoes, 7.5% of CIPC accumulates after 125d treatment, residual CIPC cannot be completely eliminated in various cooking modes, and chlorpropham registration has been declared to be suspended in 2019 by the european union due to food safety problems such as potential carcinogenesis. The use of chlorpropham on potatoes has been banned in japan and australia.
Disclosure of Invention
In view of the above, the application provides a pesticide composition and an application thereof in bud inhibition and fresh-keeping of potatoes, which can reduce the number of times of pesticide application, improve the bud inhibition effect, improve the starch content of the stored potatoes, reduce the rotting rate, improve the storage quality, and solve the problems of pesticide residue and food safety caused by the traditional chemical pesticides.
In order to solve the technical problems, the technical scheme provided by the application is the application of a pesticide composition in bud inhibition and crop quality improvement, and the active ingredients of the pesticide composition comprise: the composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is naftidrofuryl acid, and the active ingredient B is 3-decene-2-ketone.
Preferably, the application for inhibiting the buds and improving the quality of the crops is the application for inhibiting the sprouting of the potatoes during the storage period and improving the storage quality of the potatoes.
Preferably, the weight ratio of the active ingredient A to the active ingredient B is 10-30: 3-8.
Preferably, the weight ratio of the active ingredient A to the active ingredient B is 10-15: 4-6.

3-Decen-2-one, 3-Decen-2-one in English common name, 3D2 for short, is mainly used as an inhibitor for inhibiting the sprouting of harvested potatoes, and achieves the effect of bud inhibition by destroying the integrity of cell membranes, causing cell rupture, meristem necrosis and germinated eye tissue necrosis. Because the potato sprout inhibitor is a naturally-occurring green, safe and pollution-free substance, the 3-decene-2-ketone is used as the sprout inhibitor, so that the human health is not affected at all, and the sprouting rate of the potatoes during storage can be effectively reduced through multiple times of fumigation treatment. The disadvantages are short duration, need of multiple use and higher use cost. It can only be used when most potatoes germinate. After the tender shoots are killed, the killed tender shoots become black, which affects the appearance and sales. In addition, the potatoes need to be applied for a plurality of times during the storage period, the lasting period is 20-30 days, the use cost is high, and the potato bud necrosis caused by the repeated use affects the sale and the potato seed germination.
The English common name of the sodium furoate is dikegulac-sodium, abbreviated as DK. The naftidrofuryl belongs to saccharide derivatives, is an important intermediate raw material for synthesizing vitamin C in the field of medicine, is a plant growth inhibitor, and belongs to a systemic compound. It has effects of inhibiting synthesis of plant hormone, breaking apical dominance, and inhibiting stem elongation. The product can be directly sprayed or fumigated to inhibit cell division in apical meristem, remarkably inhibit growth of bud, effectively reduce germination rate of potato during storage, and has long lasting period, low use frequency, low administration cost and low residue.

Among them, treatment 3 and treatment 9 showed the best efficacy index.
Wherein the 3-decene-2-ketone has a good effect of inhibiting buds in a short time, but the buds are almost completely killed, and after the potatoes are treated by 150ppm of 3-decene-2-ketone, the buds can be effectively killed in a short time, the number of the buds is reduced, but the side effect of bud eye necrosis is brought, and the sale is seriously influenced. And the potato tender shoots grow out again with the lapse of time, and the lasting period is too short. When 3-decen-2-one is used many times, the problem of the shelf life is solved, but dead buds and bud eye necrosis seriously affect the sale.
Starch content determination shows that the sodium furoate and 3-decene-2-ketone hot fogging concentrate composition can inhibit the reduction rate of starch content of potato blocks and has a certain relieving effect on quality reduction in a storage period. The potato pieces were normal during the test period and no phytotoxicity symptoms were observed.
