Problems solved by technology

[0010] The purpose of the present invention is to solve the problems that the siliques of Brassica napus are particularly easy to crack when they are mature, resulting in a short time for suitable mechanical harvesting operations, high loss rate of rapeseed during mechanical harvesting, and reduced yield. It aims to provide a 2-4D Butyl Ester and Diquat as Active Ingredients of Rapeseed Anti-Horn Cracking Agent

Embodiment 1-3

[0035] Example 1-3: Preparation of 20% 2-4D butyl ester and diquat water dispersible granules

[0036] At room temperature (4-28°C), add the active ingredients 2-4D butyl ester and diquat into the carrier according to the formula ratio in Table 1, and add wetting agent, dispersant, filler, etc., and mix them. Add water after jet milling, then knead, granulate, dry, and sieve to obtain water-dispersible granules.

Embodiment 4

[0039] Embodiment 4: field test

[0040] Test location: Rapeseed test base in Huangmei County, Huanggang City, Hubei Province

[0041] Test material: H305

[0042] Test medicament: 20% 2-4D butyl ester and diquat aqueous suspension, 20% diquat aqueous solution, and clear water corresponding to Example 2.

[0043] Experimental design: random block group, 3 repetitions, each repetition area 666.67m 2 (1 mu), use a knapsack sprayer to spray stems and leaves during the yellow ripening stage of rapeseed (when the silique seeds in the upper part of the main inflorescence turn color); spray 30 kg of water per mu.

[0044] Test method: measure the anti-cracking angle index, water content of siliques, yield and other indicators at the mature stage.

[0045] A. The method for measuring the anti-cracking angle index is: when the rapeseed siliques are fully mature (45 days after the final flowering), take 10 plants of the same growth in each plot, cut off the main inflorescence silique...

Abstract

The invention discloses a pod shatter resist for oilseed rape and application thereof. The pod shatter resist for oilseed rape is a water-dispersible granular compound product prepared by adding a pesticide-allowable aid to 2-4D butyl ester and aquacide as active ingredients. The pod shatter resist for oilseed rape has the advantages that the pod shatter resist can maintain photosynthesis of a plant during dehydration, make up yield loss due to dehydration, reduce grain loss during harvesting and improve pod shatter resistance, the yield is 3-5% higher than that from the use of purely chemical drying, and economic benefit and production benefit are effectively improved; the pod shatter resist is convenient to use, low in cost and high in benefit and is efficient.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an anti-horn-cracking agent for rape containing diquat and 2-4D butyl ester, which is suitable for reducing shattering loss and improving horn-cracking resistance of rape during the harvest period. Background technique [0002] Rapeseed is the most important oil crop in my country, accounting for more than 40% of edible vegetable oil in my country. The main rape producing areas in my country are mainly distributed in the Yangtze River Basin (accounting for 85% of the total rapeseed area in the country), the Huanghuai River Basin and Northwest China. The development of rapeseed production is of great significance and role in ensuring the supply of edible oil in my country, maintaining national food security and meeting the needs of people's lives. [0003] However, when rapeseed is mature, it is particularly prone to natural cleavage, which generally causes a loss of about ...
